DOE proposal for the use of DOE-owned High Assay Low-Enriched Uranium (HALEU) Stored at INL (Idaho)

DOE issues Final Environmental Assessment for the use of DOE-owned High Assay Low-Enriched Uranium Stored at INL

The U.S. Department of Energy (DOE) has determined that using DOE-owned high-assay low-enriched uranium (HALEU) stored at Idaho National Laboratory (INL) will not have a significant impact on the environment and is an important tool for advancing safe, economical, low carbon nuclear energy.
In accordance with the National Environmental Policy Act (NEPA), DOE has issued a final Environmental Assessment for Use of DOE-Owned High-Assay Low-Enriched Uranium Stored at INL (DOE/EA-2087).
Based on the analysis in the environmental assessment and after consideration of public comments received on the draft environmental assessment, DOE has determined that using DOE-owned HALEU currently stored at INL to fabricate fuel at INL's Materials and Fuels Complex (MFC) and possibly also the Idaho Nuclear Technology and Engineering Center (INTEC) to support initiatives by U.S. companies to develop and deploy new reactor technologies will not result in a significant impact on the environment.

DOE invites public comment on Draft Environmental Assessment for the use of DOE-owned High Assay Low-Enriched Uranium Stored at INL

The U.S. Department of Energy (DOE) invites the public to review and comment on a draft environmental assessment for a proposal to fabricate fuel at Idaho National Laboratory's Materials and Fuels Complex (MFC) and/or the Idaho Nuclear Technology and Engineering Center (INTEC) to support efforts by U.S. companies to develop and deploy new reactor technologies.
Under requirements of an Environmental Impact Statement performed in 2000, DOE uses an electrorefiner at MFC to refine and down-blend spent fuel that contains highly-enriched uranium material generated decades ago in the Experimental Breeder Reactor-II (EBR-II). This produces high-assay low-enriched uranium (HALEU) that is currently stored at INL. DOE proposes expanding capabilities at MFC and INTEC to convert this metallic HALEU into fuel for research and development purposes. HALEU contains a higher enrichment (by percentage) of uranium-235 -- a fissile isotope in nuclear fuel that produces energy -- than fuel used in the current fleet of U.S. power reactors. Conventional light water reactors (LWRs) use low-enriched uranium (LEU) fuel, (3 to 5 percent uranium-235) while HALEU contains between 5 and 20 percent.
Currently, there are no commercial facilities in the U.S. immediately capable of producing HALEU, and several advanced reactor designers have expressed interest in using HALEU fuel with their designs to achieve higher efficiencies and longer core lifetimes.
The federal government proposes fabricating approximately 10 metrics tons of HALEU nuclear reactor fuel, to support near-term research, development and demonstration needs of private-sector developers and government agencies, including advanced reactor developers.

State legislators contemplate uranium conversion facilities in Wyoming

Legislators are investigating ways to allow for potential uranium conversion facilities in Wyoming, the next step in the development of enriched uranium, which can be used in nuclear power reactors. The Joint Minerals, Business and Economic Development Committee , which chooses mineral-related topics to be considered in next year's legislative session, also decided at a meeting Monday (Oct. 10) to update obsolete language in Wyoming law that addresses potential nuclear waste storage in the state.
Wyoming's uranium industry is confined to mining, with four companies that dig precious yellowcake from the ground. After that, the uranium is shipped out of the state. In an attempt to add value before that product leaves the state's borders, the Wyoming Business Council is investigating uranium conversion facilities. (Star-Tribune Oct. 15, 2016)


U.S. inventories of highly-enriched uranium reduced by 20%

For the first time in 15 years, the U.S. has declassified and released data on its inventory of highly-enriched uranium (HEU). The data is as of September 30, 2013.
The fact sheet from the White House Press Secretary's office says "from 1996 to 2013, U.S. HEU inventories decreased from 740.7 metric tons to 585.6 metric tons. This reflects a reduction of over 20 percent." Further reductions in the inventory are "ongoing" according to the news release.
Some of the released data indicates that, of the inventory on September 30, 2013, 499.4 metric tons was for national security and non-national security programs like nuclear weapons and naval propulsion. The remaining amount, "41.6 metric tons was available for potential down-blend to low enriched uranium or, if not possible, disposal as low-level waste, and 44.6 metric tons was in spent reactor fuel."

Rosatom in talks to build uranium enrichment plant in the U.S.

Russia's atomic agency Rosatom is in talks to build a uranium enrichment plant in the United States, its chief executive was quoted as saying on Wednesday (Aug. 25). In an interview with the Financial Times, Sergei Kiriyenko declined to provide details on the U.S. deal. (Reuters Aug. 25, 2010)


NRC to hold workshop on the future of uranium conversion/deconversion facilities

The Nuclear Regulatory Commission (NRC) is holding a workshop on February 22, 2008, with stakeholders to seek comment on the proposed quantity thresholds of uranium hexafluoride and uranium tetrafluoride either used for, or derived from, the conversion of uranium oxide to uranium hexafluoride and/or for the deconversion of depleted uranium hexafluoride to an oxide.

Import of Russian LEU to the U.S.

USEC signs multi-year contract with Russia's TENEX for low enriched uranium supply

USEC Inc. has signed a multi-year contract with Russia's Techsnabexport (TENEX) for the 10-year supply of low enriched uranium (LEU).
Under the terms of the contract, the supply of LEU to USEC will begin in 2013 and ramp up until it reaches a level in 2015 that is approximately one-half the level currently supplied by TENEX to USEC under the Megatons to Megawatts program with the mutual option to increase the quantities up to the same level as that program. Unlike the Megatons to Megawatts program, the quantities supplied under the new contract will come from Russia's commercial enrichment activities rather than from downblending of excess Russian weapons material. (USEC Mar. 23, 2011)

Trade deal signed on import of Russian enriched uranium to the U.S.

U.S. nuclear power reactors will be able to obtain more supplies of Russian enriched uranium for fuel, under a trade deal signed by the two countries on Feb. 1, 2008. The agreement allows Russia to boost exports to the United States while minimizing any disruption to the United States' domestic enrichment industry. The deal is allowing for sales of Russian enriched uranium directly to U.S. utilities. Before the agreement, such direct transactions were not permitted. For years, the U.S. government has restricted Russian uranium shipments, fearing Russia would dump uranium in the U.S. market and financially hurt the major American uranium supplier, USEC Inc. A spokesman for the Russia's Atomic Energy Agency said with the new trade deal "the volumes of direct deliveries of uranium enrichment services may total 20 percent of the market".

U.S. DOC releases draft agreement allowing for limited uranium imports from Russia

The Department of Commerce and the Russian Federation's Federal Atomic Energy Agency (Rosatom) have initialed a draft amendment to the Agreement Suspending the Antidumping Investigation on Uranium from the Russian Federation (Suspension Agreement). The proposed amendment will allow the Russian Federation to export Russian uranium products to the U.S. market in accordance with the export limits and other terms detailed in the amendment. The Department is now inviting interested parties to comment on the text of the proposed amendment. Comments must be submitted within thirty (30) days from December 4, 2007.

Federal Register: December 4, 2007 (Volume 72, Number 232) p. 68124-68127 (download full text )

According to the draft agreement, the annual export limits are as follows:
[kg U]
Unat contained *)
[t U]
Separative Work contained *)
[million SWU]
*) calculated, based on LEU product assay of 4.4% and tails assay of 0.3%; conversion loss 0.5%

The bulk of the deliveries is to start in 2014, when the US-Russia HEU agreement for the deliveries of LEU downblended from Russian nuclear weapons uranium will have ended. As the US-Russia HEU agreement comprises the annual downblending of approx. 29 t HEU into approx. 910 t LEU (at 4.4% assay, containing 5.5 million SWU), the new deliveries will substitute only about half of the annual deliveries made under the US-Russia HEU agreement.
Russia will have sufficient enrichment capacity available from 2011, as the re-enrichment agreements with Urenco and Eurodif expire in 2009-2010, thereby setting free an annual capacity of 2.58 million SWU. In addition, from 2014, no more blendstock enrichment will be required for the downblending of HEU.
It is, however, unclear, where Russia will procure the necessary natural uranium, as Russia's domestic production was just 3400 t U in 2006.


Russian LEU exports to the US should not be subject to US import duties, court rules

Exports of Low-Enriched Uranium (LEU) to the US should not be covered under a Commerce Department-imposed restriction on Russian "uranium products" sent to the US, the U.S. Court of International Trade (CIT) said September 26, 2007.
In its opinion, the CIT cited a series of cases involving LEU exports to the US by French enricher Eurodif. According to the decisions in those cases, enrichment is a service, rather than a good, and therefore not subject to the relevant US import duties.
The US government, joined by USEC, had initially argued that those decisions did not apply to the restriction on Russian material. But, as the court decision put it, the government now "does not oppose a remand" -- a directive to Commerce to rewrite the restriction -- to exclude LEU from the scope of its review. In issuing its remand for "re-determination," the CIT said the government's acknowledgment was "well-founded, because Commerce must abide by the Eurodif decisions." (Platts Sep. 28, 2007)

U.S. ITC votes against Russian uranium imports to U.S.

On July 18, 2006, the U.S. International Trade Commission (ITC) determined that terminating the suspended investigation on imports of uranium from Russia would be likely to lead to continuation or recurrence of material injury within a reasonably foreseeable time.
As a result of the Commission's affirmative determination and the Department of Commerce's recent affirmative finding, the existing suspension agreement will remain in place.


US DOC dumping case against Eurodif and Urenco


On March 3, 2005, the United States Court of Appeals for the Federal Circuit reversed the U.S. Court of International Trade's 2003 decision regarding subsidies for Eurodif, holding that overpayment for uranium enrichment services by foreign government entities cannot constitute a countervailable subsidy. (U.S. enricher USEC had alleged that French utility EdF had paid Eurodif greater than adequate compensation for the enrichment of uranium.)

GLE Paducah Laser Enrichment Facility project, Kentucky

DOE sells depleted uranium tails for re-enrichment at Paducah Laser Enrichment Facility project

The US Department of Energy (DOE) has agreed to sell depleted uranium from the Paducah Gaseous Diffusion Plant to enrich at a new state-of-the-art facility in western Kentucky. Construction and operation of the $1 billion facility by GE-Hitachi's Global Laser Enrichment is estimated to bring approximately 800 to 1,200 jobs to the local community. (WKMS Nov. 10, 2016)

Depressed uranium market hampering project of laser enrichment plant for tails re-enrichment at Paducah

Market conditions and investor changes appear to have slowed progress toward a planned laser uranium enrichment facility near the U.S. Department of Energy's Paducah Gaseous Diffusion Plant. Local, state and federal officials applauded the announcement three years ago by Global Laser Enrichment, a subsidiary of GE-Hitachi, that it had entered into exclusive negotiations with the U.S. Department of Energy for the sale of the depleted uranium hexafluoride inventory and potential construction of a commercial uranium tails processing facility in Paducah. [...]
Earlier this year, GE-Hitachi announced its desire to reduce its equity interest in GLE, according to information on its website.
In Silex's 2016 annual report, Michael Goldsworthy, CEO/managing director, noted: "The global nuclear fuel markets remained depressed during the year and continued to create a challenging business environment for Silex and GLE." In a restructuring agreement, Silex has an option to become a shareholder in GLE and will take the lead in searching for new investors, according to Goldsworthy. [...]
The process of transferring the land for the GLE facility from state to local control for use in economic development is underway, according to officials with the Paducah Area Community Reuse Organization. [...]
Paducah Mayor Gayle Kaler said she would still like to see the GLE project materialize but understands the current economic realities. "It's not dead (GLE)," she said. "It's that uranium prices are so low that it doesn't make economic sense to invest in a facility like that at this time." (Paducah Sun Oct. 23, 2016)

Cameco writes down complete CDN$ 184 million investment in GE-Hitachi Global Laser Enrichment LLC (GLE)

"During the quarter, a decision was made by the majority partner of GLE to significantly reduce funding of the project. As a result, Cameco recognized an impairment charge of $183,615,000, which represents the full amount of Cameco's investment." (Cameco Oct. 29, 2014)

License application for Paducah Laser Enrichment Facility project to be filed in September 2014

On Jan. 20, 2014, Global Laser Enrichment (GLE) advised the NRC of GLE's intent to prepare a license application for the authority to construct and operate a laser enrichment facility under 10 CFR Part 70. GLE expects to submit the license application for the Paducah Laser Enrichment Facility (PLEF) by September 2014.

GE-Hitachi proposes to build laser-based uranium enrichment plant at Paducah site

GE-Hitachi has submitted a proposal for the beleaguered Paducah Gaseous Diffusion Plant that could help preserve many of the 1,200 jobs there. The plant had been scheduled to close last year, but a deal reached in May kept it open for another year. It currently is enriching depleted uranium for the Tennessee Valley Authority and for a Washington state utility called Energy Northwest. The Paducah Sun reports GE-Hitachi is proposing to build a new laser-based uranium enrichment plant at the site. (AP Feb. 24, 2013)

Silex evaluates opportunity to build laser enrichment plant in Paducah, Kentucky, to re-enrich depleted uranium

On Nov. 20, 2012, Silex Systems Limited confirmed that a preliminary evaluation is being undertaken regarding the potential to build an additional enrichment plant using the SILEX Technology at the site of the existing gaseous diffusion enrichment plant in Paducah Kentucky, USA. The evaluation includes early stage discussions between General Electric-Hitachi Global Laser Enrichment LLC (GLE) and the owner of the Paducah facilities, the US Department of Energy (DOE) and is dependent on further detailed analysis.
GLE is proceeding with the evaluation of the opportunity to build a plant utilising the SILEX Technology to enrich 'high assay tails' stockpiles - potentially worth approx. $3 billion after enrichment (based on current price and process assumptions). There are approximately 100,000 metric tons of 'high assay tails' owned by the DOE and stockpiled at its Paducah and Portsmouth (Ohio) facilities. Silex believes that much of this material could be processed with the efficient SILEX enrichment technology to produce either natural assay uranium or enriched uranium for further use as nuclear fuel.

Uranium hexafluoride contamination class action filed against Honeywell Metropolis conversion plant

A class action federal lawsuit has been filed in Metropolis, Illinois, against Honeywell International for uranium hexafluoride (UF6). 
The federal complaint alleges that "Exposure to this radioactive and toxic mixture in the environment through human pathways can cause grave bodily injury and has created a need for a mitigation/abatement program to protect the public from further risk of being harmed by Honeywell's tortious contamination of their properties."

UF6 leak at Honeywell Metropolis uranium conversion plant causes emergency alert

The Honeywell plant in Metropolis experienced a leak of UF6, or uranium hexafluoride, on Saturday (Aug. 1). Honeywell spokesman Peter Dalpe said at about 6 p.m. Saturday the plant had declared a plant alert and notified the U.S. Nuclear Regulatory Commission of a UF6 leak. All employees were accounted for and there were no reported injuries, Dalpe said.
The plant activated its emergency response procedures and emergency teams responded. There was no evidence of off-site impact as of Saturday night. Around 8 p.m., Dalpe said plant personnel confirmed the leak had been stopped and went into "plant emergency status" which Dalpe said is the lowest level of alert at the plant.
For a short time following the initial alert of a leak, Dalpe said there was a "shelter-in-place" alert for the surrounding community as a precaution. "It's a system that alerts people in the area that they should shelter in place, stay indoors, close their windows, in case the material goes out to the community," he said. Plant personnel were working Saturday night to determine how much material was released and the plant will conduct a thorough investigation of the incident, Dalpe said. (Paducah Sun Aug. 2, 2015)
Until the company's investigation into the leak is complete, production at the plant will stay at a standstill. (Paducah Sun Aug. 3, 2015)

Honeywell Metropolis conversion plant shut down after UF6 leak

The Honeywell Plant has confirmed there was a leak of UF6 about 7:35 p.m. Sunday (Oct. 26). The company issued a news release late Sunday. It read that the "leak has been contained and a trained response team is currently working to ensure the leak has been stopped completely." Honeywell spokesman Peter Dalpe wrote that "there have been no injuries and there is no indication that any material has left the building." (WSIL TV Oct. 26, 2014 - emphasis added)

"On October 26, at 8:24 p.m. EST, Honeywell Metropolis Works experienced a leak of UF6 inside the Feed Materials Building (FMB). The initial indication was a chemical alarm near the UF6 cold traps. An operator noticed on the room monitor video screen a haze in the air inside the fourth floor of the FMB. This haze indicated a UF6 leak. The leak occurred during a routine sublimation and draining of a cold trap. Honeywell operators implemented emergency procedures to shut down and evacuate the FMB. Emergency responders reentered the FMB to isolate the cold trap and stop the leak. Honeywell stated that the haze in the FMB was cleared by 8:55 p.m. EST. An 'All Clear' was declared by Honeywell at 3:16 a.m. EST on October 27.
Members of the public outside the plant reported a cloud emanating from the building for five minutes before the mitigation spray towers were activated by Honeywell staff. The plant is currently shut down. No injuries were reported."
(NRC Preliminary Notification PNO-II-14-008, Oct. 27, 2014 - emphasis added)

"A Region II inspector was dispatched to Honeywell on October 27. The inspector has confirmed that a small UF6 leak occurred during heating and draining operations. The UF6 vaporized and interacted with moisture in the FMB [Feed Materials Building] allowing it to convert to UO2F2 (a solid form of uranyl fluoride which is a yellow powder) and HF (hydrogen fluoride gas). The NRC inspector observed and confirmed the UO2F2 deposits were contained in the FMB and were within a two to three foot radius of the leak area. The NRC inspector verified that Honeywell staff implemented their emergency plan by assessing the spill and took immediate actions that included sounding the plant emergency alarm, accounting for all personnel, assembling the emergency response team, assessing the event by characterizing that some HF was visible coming from the top of the building, activating the spray system and directing it towards the FMB windows to prevent any HF from reaching the public, directing operators to don safety gear and re-enter the facility to stop the spill of UF6, isolating and cooling the leaking cold trap (cooling the trap forces the UF6 to solidify), placing a vacuum system in service to capture vaporized UF6, and monitoring fence HF detectors from the fluorine plant control room which indicated no detectable HF at the fence."
(NRC Preliminary Notification PNO-II-14-008A, Oct. 31, 2014 - emphasis added)

"[...] the NRC inspection found that Honeywell did not recognize that the HF released from the FMB warranted an emergency classification of ALERT. Honeywell agreed with the NRC findings and subsequently reported their failure to properly classify the October 26 event to the NRC at 2:04 p.m. EST on November 5 [NRC Event Number 50594]."
(NRC Preliminary Notification PNO-II-14-008B, Nov. 6, 2014 - emphasis added)

"The NRC has concluded the implemented actions provide high confidence Honeywell will properly assess any future events in accordance with the requirements of the emergency plan and has authorized restart of the Honeywell facility."

NRC steps up supervision of Metropolis conversion plant in view of worker lockout

A lockout of about 135 union employees at a Honeywell International Inc uranium conversion plant in Illinois is poised to extend past a month as the two sides remain apart on several issues. Production and maintenance employees at the Metropolis, Illinois, plant who are members of United Steelworkers Local 7-669 have been locked out since the start of August, after a three-year contract expired.
Honeywell has continued to operate the plant after the lockout, with the remaining roughly 135 plant employees who are non-union, as well as with contingent workers.
The Nuclear Regulatory Commission has taken more precautions since the lockout began, including continuously staffing the plant during the first 72 hours and increasing safety inspections to once a week from the typical schedule of about once a month. No "significant issues" have been found, but the NRC will continue the stepped-up inspection schedule until the work stoppage is resolved or the agency is satisfied the plant can operate long-term without any issues, said NRC spokesman Roger Hannah.

NRC authorizes Metropolis conversion plant to resume operations after upgrades

The Nuclear Regulatory Commission staff has determined that the company may resume all NRC-licensed activities.
In October 2012, the NRC issued a confirmatory order to Honeywell describing the steps the company would have to take before it could resume its uranium conversion operations. That order came after inspections earlier in 2012 identified concerns related to the likelihood of a release of uranium hexafluoride following an earthquake or tornado.
The plant has been shut down since May 2012 and the company has been enhancing and modifying equipment to meet the requirements of that order. In June, the NRC allowed the plant to begin limited operations, but today's decision authorizes operation of all of the plant processes covered by its NRC license.

NRC issues Confirmatory Order to Honeywell on hardening of Metropolis conversion plant against seismic and wind events

The U.S. Nuclear Regulatory Commission has issued a Confirmatory Order to Honeywell International, Inc., outlining actions the company must take before it can resume its uranium conversion operations at the Honeywell Metropolis Works facility. The facility has been shut down since May 9.
During an inspection in May that examined how the facility would fare in a major earthquake or a tornado, the NRC concluded that such an event could result in a higher risk to the public than originally assumed. The inspection identified that process equipment in the facility lacks seismic restraints, support and bracing that would assure integrity during a significant seismic or wind event. Specifically, the amount of uranium hexafluoride that could be released into the environment should the process equipment be damaged by such an event could be significantly larger than assumed in the facility's Emergency Response Plan.

Honeywell pays US$ 12 million fine for illegal waste storage at Metropolis conversion plant

On March 11, 2011, Honeywell announced that it has resolved a U.S. government investigation into permitting and storage issues at its Metropolis, Ill., facility.
As part of a plea agreement with the U.S. Department of Justice, the company will pay a total of $12 million in fines and supplemental environmental projects to resolve the matter, which involved the storage of a regulated material without a proper permit.

Residents concerned about Honeywell's plan to close old calcium fluoride ponds at Metropolis conversion plant by in situ cementation

The plan has outraged several people in Southern Illinois, as they are concerned about the possibility of the ponds leaking and creating a disaster in the region.
"It is a concern; (the waste) is there," said Mike Riley, a former longtime Honeywell employee who is now the USW's health and local safety representative. "I don't see how putting concrete with it is going to get rid of the problem."
In 2000, an EPA report on stabilization and solidification projects at badly polluted sites across the country found that concentrations of toxins at those sites were reduced enough to generally meet government standards. Unfortunately, the EPA also noted in the same report that the long-term effectiveness of solidification and stabilization is unknown. The EPA quoted various studies showing that "cement-based stabilized wastes are vulnerable to the same physical and chemical degradation processes as concrete and other cement-based materials," which means they have the "potential to disintegrate over a period of 50 to 100 years."
That timeframe is what concerns Metropolis Mayor Billy McDaniel. "I want it where, 50 years from now in our community, we don't have an issue at Honeywell or at any other plant, that could be taking lives or having babies born with deformities," McDaniel said. "We want things done right, and in the right way, the first time." (The Southern Jan. 23, 2011)

Honeywell submits decommissioning plan for closure of old calcium fluoride ponds at Metropolis conversion plant

On December 2, 2010, Honeywell submitted a decommissioning plan related to closure of existing surface impoundments at the Metropolis Works facility.

Honeywell submits license amendment request for closure of old calcium fluoride ponds at Metropolis conversion plant by in situ cementation

"Honeywell International, Inc. is the holder of Source Materials License No. SUB-526 (NRC License), a 10 Code of Federal Regulations (CFR) Part 40 license last renewed by the U.S. Nuclear Regulatory Commission (NRC) in 2007. Under this license, the licensee operates its Honeywell Metropolis Works, Inc. (MTW) formerly ''Allied Signal'' (Allied) plant at Metropolis, Illinois, where it converts uranium ore concentrates to uranium hexafluoride (UF6) by the ''fluoride volatility process.''"
"This license amendment request relates to an area of the MTW site known as the CaF2 Pond Area, where MTW formerly precipitated calcium fluoride (CaF2). The CaF2 Pond Area includes four surface impoundments known as Ponds B, C, D, and E. Pond A was closed in 2001 and the CaF2 materials removed from the site.
Ponds B, C, D, and E were constructed from 1974 through 1979 and currently store CaF2 materials which contain trace amounts of natural radioactive isotopes including, but not limited to uranium and thorium. This material was generated prior to 1982 when MTW used a fluoride removal process that involved use of calcium hydroxide to precipitate calcium fluoride in the ponds. The installation of a CaF2 recovery system in 1982 curtailed the use of the ponds for calcium fluoride precipitation. Currently, no material is discharged to Ponds B, C and E, and Pond D only receives flow from MTW's National Pollutant Discharge Elimination System (NPDES) permitted wastewater treatment system prior to discharge at permitted Outfall 002.
MTW is required by its RCRA permit to close Ponds B, C, D and E by 2020. As part of the closure process, MTW has submitted to the Illinois Environmental Protection Agency (IEPA) an application to modify MTW's RCRA permit to close the ponds in place using in situ sludge stabilization with a pozzolanic cement material, construction of an engineered cap and long-term maintenance." [emphasis added]

The four ponds cover a combined surface area of 23,900 square metres and contain a combined volume of 88,100 cubic yards [67,357 cubic metres] of CaF2 sludge.
The uranium concentration in the sludge is in the 200 - 300 ppm U (0.02 - 0.03% U) range, so the total uranium contents is approximately in the 20 - 30 t U range. [The uranium concentration is higher than that found in several uranium deposits currently being developed for mining in Namibia, such as Trekkopje, Valencia, and Etango.]

Hydrofluoric acid leak at Honeywell Metropolis conversion plant

"At around 3 p.m. this afternoon, the Metropolis plant experienced a leak of hydrofluoric acid at its tank farm. The plant sounded its emergency siren and activated its emergency response procedures as a precaution. The release was immediately contained by the plant's water mitigation system and a team immediately began working to stop the leak. The leak was stopped before 5 p.m. local time.
At this point, there are no indications of off-site impact from the release and it did not involve any radioactive materials. All on-site personnel were accounted for and there were no injuries." (from the Honeywell official statement, according to WPSD Local 6 Dec. 22, 2010)

The United Steelworkers (USW) today (Dec. 23) has again sounded the alarm over concerns to the community about observations and reports on plume leakages yesterday (Wed. Dec. 22) at the Honeywell uranium conversion facility that is involved in a five-month-old labor dispute.  
According to news reports, the plume leak occurred at approximately 3 p.m. (CT).
USW pickets outside the Honeywell facility noticed a large plume from the hydrofluoric acid (HF) storage area.  The plant's mitigation towers, which spray water to knock down any escaping gas, were turned on and sirens sounded. The towers sprayed for approximately an hour and a half. The emergency siren was turned on, then immediately off, and then later on again.
USW Local 7-669 President Darrell Lillie said, "We have been warning everyone for months that there is the possibility of a fatality and major breach of public safety at this plant. The workers in the plant do not have the experience it takes to safely run this facility."
Honeywell has been running the plant with replacement workers since locking out the union workforce of 228 on Jun. 28.  The plant has been recently cited for violations by the U.S. Nuclear Regulatory Commission (NRC), and is under a separate investigation by the U.S. Environmental Protection Administration (EPA) concerning improper storage of potassium hydroxide.
"The community should be outraged at the way the facility is being operated and their safety at risk, and demand that someone take action before this becomes the present day Katrina," Lillie said.
According to the USW local union leader, Honeywell issued a statement that claimed the plume was a "small release" of hydrofluoric acid.  However, the experienced union workers from the plant, who are on the picket lines, could do nothing but watch with skepticism that a so-called "small" release doesn't require the mitigation towers to run for more than an hour.

NRC accepts blending of CaF2 waste to meet release criteria

By letter dated Sep 14, 2001, the NRC accepted a proposal by Honeywell to blend its calcium fluoride settling pond waste with natural fluorspar (CaF2) to meet the uranium concentration criterion of 212 pCi/g (7.84 Bq/g; 313 ppm) for the unrestricted release of the material. The blended material is to be trucked to Hastie Trucking & Mining Company in Cave-In-Rock, Illinois, where it is to be manufactured into a fluorspar briquette for use as a fluxing agent in the steel industry. This arrangement evades the necessity to dump the waste material in a Texas landfill.


Missing shipment of uranium hexafluoride conversion waste

A shipment of CaF settling pond waste left the site on July 25, 2001 and apparently did not arrive on July 27, 2001 at the Andrews County WCS in Texas. The shipment, one of several, consisted of 44,480 pounds [20.2 metric tonnes] of 80% CaF and 20% lime with less than 500 ppm natural uranium contained in it. The natural uranium is calculated at about 19 pounds [8.6 kg] total contained in the shipment. The driver reported that the shipment was delivered, but there is no paperwork to support the delivery.

Hitachi to report US$ 620 million loss upon withdrawal from laser isotope separation enrichment demonstration facility project in Wilmington: Electronics giant Hitachi Ltd. is set to lose tens of billions of yen this fiscal year due to the withdrawal from a project to develop a new method of uranium enrichment by a joint venture in the United States.
Hitachi is expected to report a 70 billion yen ($620 million) non-operating loss by the time books are closed for fiscal 2016 at the end of March, said Mitsuaki Nishiyama, a senior vice president of the Tokyo-based conglomerate, in a news conference on the company's performance through the third quarter. The deficit is largely attributed to the joint venture GE Hitachi Nuclear Energy Inc. withdrawing from the uranium enrichment project. Due to this decision, Hitachi no longer expects any profits from the North Carolina-based company, of which it owns 40 percent and the rest by General Electric. (Asahi Shimbun Feb. 2, 2017)

Test Loop Program Phase I Milestone completed at GE-Hitachi laser isotope separation enrichment demonstration facility in Wilmington (North Carolina): On May 21, 2013, Silex Systems Limited announced that the Test Loop Program Phase I Milestone: Technology Demonstration, has been successfully completed at GE-Hitachi Global Laser Enrichment's facility in Wilmington, North Carolina, USA.

NRC fines GE-Hitachi $45,000 for multiple security violations at laser isotope separation enrichment demonstration facility in Wilmington (North Carolina): The U.S. Nuclear Regulatory Commission has fined GE-Hitachi Nuclear Energy $45,000 for multiple security violations at a North Carolina facility using classified technology to test whether lasers can be used to enrich uranium.
A redacted copy of an NRC violation letter provided to The Associated Press on Thursday (Oct. 20) following a Freedom of Information Act request said investigators identified five violations including "a significant lack of management attention." Details of the violations described by the letter were blacked out by nuclear regulators before it was released to The AP. While some violations were "willful," "no actual consequences resulted," the NRC said.
The violations involved a contractor's employee working at the GE-Hitachi's Global Nuclear Fuels facility near Wilmington, where the company is using top-secret technology to find out whether lasers can effectively enrich uranium instead of costlier centrifuges, company spokesman Christopher White said.

On July 30, 2009, Global Laser Enrichment (GLE) announced the start-up of a "test loop" to evaluate a next-generation uranium enrichment technology that GLE is developing. The test loop is designed to validate the commercial feasibility of the technology and advance the design of the equipment, facility and processes for the planned commercial production facility. GLE anticipates gleaning sufficient data from the test loop by the end of 2009 to decide whether to proceed with plans for a full-scale commercial enrichment facility.

On June 20, 2008, Cameco Corporation announced it is joining a uranium enrichment business venture in the United States. Cameco has finalized an agreement with GE Hitachi Nuclear Energy (GEH) whereby a Cameco subsidiary will provide $123.8 million (US) to acquire a 24% interest in Global Laser Enrichment (GLE) based in Wilmington, North Carolina. The remainder of GLE is owned indirectly by General Electric Company (51%) and Hitachi Ltd. (25%).

On May 14, 2008, Global Laser Enrichment (GLE), a subsidiary of GE Hitachi Nuclear Energy (GEH), announced that the U.S. Nuclear Regulatory Commission (NRC) has approved a license amendment (to an existing nuclear facility license) to operate a Test Loop for GLE's next generation, SILEX laser-enrichment technology.

GE Hitachi slows construction of Wilmington laser enrichment plant down due to market conditions

GE Hitachi Nuclear Energy's Global Laser Enrichment announced plans late Wednesday (July 23) night to suspend work on development of technology done at its facility in Wilmington, which will apparently impact about two dozen workers in the area. In an email statement, a GLE official said "most contractor-based work on the project will be suspended", and later added that approximately two dozen contractors in Wilmington "support the project". The statement released Wednesday night said GLE "plans to pace development of the technology in alignment with market conditions". (WECT July 24, 2014)

Critics demand assessment of proliferation risks of laser enrichment

In a little-known effort, General Electric has successfully tested laser enrichment for two years and is seeking federal permission to build a $1 billion plant that would make reactor fuel by the ton. That might be good news for the nuclear industry. But critics fear that if the work succeeds and the secret gets out, rogue states and terrorists could make bomb fuel in much smaller plants that are difficult to detect. Iran has already succeeded with laser enrichment in the lab, and nuclear scientists worry that GE's accomplishment might inspire Tehran to build a plant easily hidden from the world's eyes.
Backers of the laser plan call those fears unwarranted and praise the technology as a windfall for a world increasingly leery of fossil fuels that produce greenhouse gases. But critics want a detailed risk assessment. Recently, they petitioned Washington for a formal evaluation of whether the laser initiative could backfire and speed the global spread of nuclear arms.
"We're on the verge of a new route to the bomb," said Frank N. von Hippel, a nuclear physicist who advised President Clinton and now teaches at Princeton University. "We should have learned enough by now to do an assessment before we let this kind of thing out." (Boston Globe Aug. 21, 2011)

Proliferation risks from laser enrichment technology exceed benefits, scientists say

The US Congress should take the lead on discouraging efforts to advance uranium-enrichment technology, argue Francis Slakey and Linda R. Cohen in an Opinion piece in this week's Nature. They believe that the newest laser enrichment technology - called separation of isotopes by laser excitation (SILEX) - offers more potential risks than benefits. It is not critical for expansion of the nuclear power industry today, or in a future where greenhouse-gas emissions are tightly capped and the nuclear industry favoured. Capital costs and regulatory policies will determine the size of that industry. "Rather, the development and potential risk of misappropriation of an enrichment facility too small and efficient to be detected could be a game changer for further nuclear proliferation," say the duo.
The US Nuclear Regulatory Commission (NRC) is considering an application to operate a full-scale commercial SILEX plant in North Carolina; this is open to public petition until 15 March. A final decision is expected to take at least another year. Slakey and Cohen urge Congress to require that proliferation risks be evaluated as part of the NRC licensing process, starting with the SILEX application. If the proliferation risks of such technologies beyond the licensee's control are deemed too high, requested users should not be licensed, they say. Such a barrier would discourage commercial research and development in this area.

GE Hitachi selects Wilmington, North Carolina, as site for potential commercial uranium enrichment facility

Global Laser Enrichment (GLE), a subsidiary of GE Hitachi Nuclear Energy (GEH), has announced it has selected GEH's Wilmington headquarters site for a potential commercial uranium enrichment facility. The planned GEH plant would result in the creation of hundreds of new technical, operational and support jobs at the site between now and 2012. Before moving ahead with full-scale production plans, GLE will first evaluate the results of a demonstration test loop, which is currently under construction, and obtain an NRC license to build and operate the commercial plant. Commercial licensing activities are currently underway to support a projected start-up date of 2012. The commercial GLE facility would have a target capacity of between 3.5 and six million separative work units (SWUs). GEH intends to make a final decision on the construction of the facility as early as the beginning of 2009. (Centre Times Daily Apr. 30, 2008)
