Trump administration’s push for U.S. uranium production opposed near Grand Canyon

By James Carr, Cronkite News | Monday, Dec. 30, 2019

As of 2018, U.S. nuclear power plant owners and operators imported roughly 90% of their uranium from Australia, Canada, Kazakhstan, Russia and a handful of other countries. Total production of uranium concentrates in the U.S. was 1.6 million pounds in 2018 – 33% less than in 2017.

La NRC Américaine autorise la centrale de Turkey Point (Floride) à fonctionner jusqu'à 80 ans.
Turkey Point licensed for 80 years of operation

06 December 2019

The US Nuclear Regulatory Commission (NRC) has approved Florida Power & Light's (FPL) application for a 20-year subsequent licence extension for Turkey Point units 3 and 4, the first time the regulator has issued licences authorising reactors to operate for up to 80 years.

The two pressurised water reactors, which are located about 20 miles south of Miami, have been in commercial operation since 1972 (unit 3) and 1973 (unit 4), when they were initially licensed to operate for up to 40 years. The NRC in 2002 issued renewed licences for a further 20 years of operation for each unit. FPL submitted a subsequent licence renewal application for a further 20 years of operation on 30 January 2018. The NRC notified FPL of the issuance of the subsequent renewed licences in a letter dated 4 December. Turkey Point 3's subsequent renewed licence expires on 19 July 2052, and unit 4's on 10 April 2053, the NRC said.

"The rationale for the NRC's decision is documented in the staff’s July 2019 final Safety Evaluation Report on the application, as well as the staff's October 2019 final Supplemental Environmental Impact Statement. The NRC's Advisory Committee on Reactor Safeguards also reviewed the safety aspects of renewing the licences," the regulator said.

The NRC is authorised under the US Atomic Energy Act to issue licences for commercial power reactors to operate for up to 40 years - a time period which it says was based on economic and antitrust considerations, rather than limitations of nuclear technology. Licences can be renewed for an additional 20 years for an operating lifetime of 60 years in a process that requires applicants to address the technical aspects of plant aging and describe how those effects will be managed, as well as evaluating potential environmental impacts of the plant's continued operation.

Subsequent licence renewals cover a further 20 years of operation beyond 60 years and focus on the management of plant ageing during the 60-80 year operating period, especially the effects of extended operation and high radiation exposure on reactor parts, concrete containment structures, piping and electrical cables, among other things. The NRC will renew a licence only if it determines that a currently operating plant will continue to maintain the required level of safety.

Almost all of the USA's currently operating nuclear reactors have already renewed or applied to renew their licences for up to 60 years of operation, and US operators are now turning to subsequent licence renewals. The NRC is currently reviewing applications for subsequent licence renewals from Exelon Corporation for Surry 1 and 2 and Dominion Energy for Peach Bottom 2 and 3, while Dominion has formally notified the regulator it intends to apply for a subsequent licence renewal for North Anna 1 and 2. According to the US Department of Energy, some 20 reactors are planning or intending to operate up to 80 years, with more expected to apply in the future as they get closer to the end of their operating licences.

Trump voudrait relancer l'industrie minière de l'uranium aux USA.
White House considering direct purchases of US mined uranium

Bloomberg News | September 6, 2019

The White House is considering a plan that would have the government directly purchase uranium from U.S. producers as it contemplates ways to revive the flagging domestic mining industry.

A group set up by President Donald Trump to study the issue is considering a request by the nuclear industry to use the Defense Production Act, a 68-year-old Cold War-era statute once invoked by President Harry Truman to help the steel industry. The plan calls for requiring the government to buy American uranium to replenish their stockpiles and for other purposes, Paul Goranson, chief operating officer for Energy Fuels Inc., said in an interview.

Energy Fuels and Ur-Energy Inc. unsuccessfully petitioned the White House to put quotas on foreign imports of uranium. The concept of direct government purchases of U.S. uranium was among ideas discussed during a roundtable with administration staff and the nuclear industry at the Old Executive Office Building earlier this week, Goranson said.

“They seem receptive to direct purchasing of material,” Goranson said. “The president intends to take bold action on this. It’s got his attention now.”

The White House didn’t immediately respond to a request for comment.

Share rise
Shares in U.S. uranium producers rose on the report. Energy Fuels jumped as much as 11% while Ur-Energy climbed as much as 10%. Cameco Corp. increased about 2%.

Trump in July rejected the Commerce Department’s recommendation that he impose quotas on uranium imports using a trade law tied to national security concerns that he invoked to impose tariffs on steel, solar panels and hundreds of billions of dollars of Chinese goods. Instead, Trump said a fuller analysis was needed and he directed his administration to identify other options. He created a nuclear fuel working group comprised of six cabinet secretaries and several other top White House officials.

The Uranium Producers of America, which represents miners including Cameco, is requesting “federal actions facilitating domestic uranium production” of at least 7.5 million pounds per year by 2025 and 10 million pounds per year by 2030, according to a letter the Santa Fe, New Mexico, trade group sent to the working group last month. That includes millions of pounds via contracts with the Department of Defense, requirements that government-owned utilities buy domestic uranium, and the creation of a new “Federal Uranium Security Stockpile.”

“We may not be able to continue any operations without immediate relief from the impact of state-backed entities, which have distorted global prices and made it more difficult for free market mines in the U.S. to compete,” the group wrote in the letter, which included a request to direct payments to domestic uranium companies.

In a separate letter, the Nuclear Energy Institute, which represents nuclear reactor operators, also recommended the working group use the Defense Production Act to “accelerate the procurement” of domestic uranium as well as “incentivize” the annual purchase of domestic uranium through a tax credit for nuclear utilities.

In addition, the trade group urged expanding an Energy Department loan program to include domestic uranium projects and to ”modernize the Nuclear Regulatory Commission’s regulatory regime to be more safety focused, risk-informed, timely, consistent, cost-contained, and transparent.”

L'origine de l'uranium aux États Unis :
US 2018 uranium purchase figures released
03 June 2019

Owners and operators of US civilian nuclear power reactors purchased a total of 40 million pounds U3O8 equivalent (U3O8e) (15,386 tU) of deliveries during 2018, according to the latest uranium marketing report from the US Energy Information Administration (EIA). Nearly 10% of that was US-origin uranium.

Total deliveries were 6% lower than 2017's figure of 43 million pounds U3O8e, the EIA's Uranium Marketing Annual Report found. Canada, at 9.6 million pounds, was the largest single country supplier to the USA in 2018, followed by Kazakhstan at 8.2 million pounds and Australia, at 7.2 million pounds. The remainder came from Russia (5.4 million pounds), Uzbekistan (2.5 million pounds) and Namibia (2.2 million pounds). US-origin purchases were 3.9 million pounds.

Du financement pour la construction de la centrale de Vogtle en Géorgie :
U.S finalizes $3.7 bln loan for Vogtle nuclear power plant
The financing for Vogtle, the first new nuclear power plant to be licensed and begin construction in the United States in more than three decades, was first announced in 2017.

REUTERS | March 23, 2019

The U.S. Energy Department on Friday finalized up to $3.7 billion in loan guarantees to finance the construction of two reactors at the delayed Vogtle nuclear power plant in Georgia, tapping a program zeroed out in President Donald Trump's latest budget.

The financing for Vogtle, the first new nuclear power plant to be licensed and begin construction in the United States in more than three decades, was first announced in 2017. The decision brings the federal government's total in loan guarantees for Vogtle to $12 billion, some of which was provided in 2014 and 2015, during the administration of President Barack Obama.

Up to $1.67 billion will go to Georgia Power Co, a subsidiary of Southern Co; up to $1.6 billion will go to Oglethorpe Power Corp; and up to $415 million will go to three subsidiaries of the Municipal Electric Authority of Georgia.

"This is the real new green deal, that's what we're looking at here folks," Energy Secretary Rick Perry told workers and politicians at a ceremony at the plant. Perry was apparently referencing the Green New Deal, a non-binding resolution in Congress introduced by Democrats that aims to spark ways to cut greenhouse gas emissions and boost investments in renewable energy, but leaves the door open for nuclear power.

Perry conceded that the U.S. nuclear industry has suffered recent challenges, but declared that nuclear power was back and said the world would be looking to the United States for nuclear technology and workers for the supply chain.

U.S. nuclear power has struggled amid rising costs for safety upgrades and in the face of competition from solar and wind power and plants that burn cheap and abundant natural gas. In 2017 utilities abandoned two unfinished reactors called V.C. Summer in South Carolina that were once hailed as the start of a U.S. nuclear power renaissance.

The reactors at Vogtle are years behind schedule, and the construction cost has soared to $20 billion or more.

Trump's budgets, including the one submitted earlier this month to Congress, have called for axing the Department of Energy's loan guarantee program that has supported numerous renewable energy and energy efficiency projects. But the previous requests never became law and this one has less of a chance with the takeover of the House of Representatives by Democrats in last year's elections.

Démentelement en cours de ce qui fut la seule installation de retraitement de déchets radioactifs des USA.
Cover marks milestone for US vitrification plant demolition

07 March 2019

Installation of a final cover has marked the end of physical work associated with the demolition of a former vitrification plant at the US Department of Energy (DOE) Office of Environmental Management's West Valley Demonstration Project (WVDP), the only commercial nuclear fuel reprocessing plant to have operated in the USA.

Work to demolish the three-storey, 10,700 square foot (994 square metre) structure was completed in September. The multi-phase demolition process involved the removal of the least-contaminated exterior parts of the facility; dismantling the heavily reinforced concrete process cell and remaining in-cell equipment; and the demolition of the crane maintenance room and transfer tunnel. Some 10,000 cubic feet of material, including a 195-ton melter and two tanks weighing over 150 tons each, had to be removed from the facility before demolition could begin. The weather-shielding cover which has now been installed over the remaining concrete slab will prevent water from infiltrating into the portion of the facility that is below ground-level.


The vitrification facility was constructed in the 1980s to solidify the wastes. Pre-treatment of waste began in 1988 with vitrification activities taking place from 1996 to 2002 during which 24 million curies of radioactivity were solidified in 600 tons of glass contained in 275 stainless steel canisters. The canisters - plus three canisters of decontamination waste - have been loaded into on-site storage casks until a permanent repository is available.

US Supreme Court to decide fate of Virginia's uranium mining ban

Mining. Com 2 nov 2018

The US Supreme Court will hear on Monday why a group of Virginia miners believe states should not have the right to ban uranium mining for public health reasons, part of a long dispute over a moratorium the state put in place on the radioactive metal in 1982.

The bid by a Virginia Energy Resources’ subsidiary and other owners of the largest US uranium deposit seeks to revive a lawsuit thrown out by a lower court that sought to invalidate Virginia’s ban because it conflicted with a federal law that regulates nuclear power generation.

President Donald Trump’s administration has backed the companies in the case.

What the US top court will have to decide is whether the state has the right to regulate uranium mining or whether it should be done by the federal government.

The plaintiffs, Virginia Uranium Inc, a subsidiary of Vancouver, B.C.-based Virginia Energy Resources, Cole Hill LLC and Bowen Minerals LLC, value the southern Virginia uranium deposit at up to $6 billion, according to court documents. Mining it could inject billions of dollars into the local economy, the plaintiffs said.

Les USA ouvrent une enquête sur leurs importations d'uranium
REUTERS | LE 18 juillet 2018

Le secrétaire américain au Commerce, Wilbur Ross, a annoncé mercredi l'ouverture d'une nouvelle enquête sur des motifs de sécurité nationale, cette fois au sujet des importations d'uranium, qui pourrait déboucher sur des droits de douane ou des quotas.

Cette enquête dans le cadre de la "section 232" a été déclenchée à la suite d'un recours déposé par deux entreprises minières américaines spécialisées dans l'extraction d'uranium, Ur-Energy et Energy Fuels. Ces dernières affirment avoir été contraintes de réduire leurs capacités de production et leurs effectifs en raison d'une concurrence étrangère subventionnée.

Wilbur Ross a précisé que l'enquête couvrirait l'ensemble du secteur américain de l'uranium, de l'extraction à l'enrichissement et aux usages industriels et militaires.

L'uranium est un composant de l'arsenal nucléaire des Etats-Unis, il sert à propulser les porte-avions et les sous-marins nucléaires de la Navy et il alimente 99 centrales nucléaires américaines fournissant 20% de l'électricité consommée dans le pays.

Wilbur Ross a souligné que la production américaine d'uranium ne couvrait plus que 5% des besoins du pays contre 49% en 1987.

Il s'agit de la quatrième enquête lancée par l'administration Trump dans le cadre de la section 232 du Trade Expansion Act de 1962, une législation auparavant seulement utilisée du temps de la Guerre froide.

L'une d'elles a entraîné l'instauration de droits de douane sur l'acier et l'aluminium, auxquels d'importants partenaires commerciaux des Etats-Unis comme l'Union européenne, le Canada et le Mexique ont riposté. Le département du Commerce conduit une autre enquête dans ce cadre sur les importations automobiles des Etats-Unis. (David Lawder Bertrand Boucey pour le service français)

L'uranium nouveau cheval de bataille de l'America First de Donald Trump?

Par Claire Fages RFI 23 mai 2018

Il s'appelle Coles Hill, c'est le plus gros gisement américain d'uranium non exploité à ce jour, du fait d'un moratoire de l'Etat de Virginie. Mais son sort est désormais entre les mains de la Cour suprême des Etats-Unis. Une première victoire pour les compagnies minières qui souhaitent relancer l'exploitation de l'uranium aux Etats-Unis, avec le soutien de l'administration Trump.

On ne sait pas encore si la Cour suprême américaine autorisera ou non l'exploitation de l'uranium de Coles Hill. L’affaire ne sera pas tranchée avant l’automne prochain. Mais que l'affaire passe au niveau fédéral est déjà une revanche pour le propriétaire du gisement Virginia Energy Resources. Il plaidait l'incompétence de l'Etat de Virginie à statuer sur les seuils de radioactivité des déchets de la mine.

« Intérêts nationaux américains »

Plus largement c'est une petite victoire pour tous les producteurs américains d'uranium. Ils se plaignent de voir leur activité décliner, à cause prétendent-ils des importations d'uranium de l'étranger. Un discours soutenu par l'administration Trump.

Après le charbon, l'acier, l'aluminium, l'uranium semble être devenu le nouveau cheval de bataille de l'«America First». En tout cas le lobby de l'uranium a lancé en janvier dernier une pétition pour limiter les importations étrangères d'uranium en vertu de la section 232 sur les intérêts nationaux américains qui a déjà justifié des tarifs contre l'acier et l'aluminium étrangers importés aux Etats-Unis.

94% d’importations et menaces russes

Il est vrai que les Etats-Unis importent 94% de leur uranium, contre 50% il y a trente ans. La pétition des groupes miniers demande qu'elles soient limitées à 75%.

Le Département américain au Commerce semble soutenir ce discours, il estimait le mois dernier qu' « une industrie américaine de l'uranium solide [était] indispensable, pour assurer les besoins futurs de la défense américaine et pour ne pas dépendre des fournisseurs d'uranium russes ou alliés des Russes ».

Des propos à remettre dans le contexte des menaces de Moscou de priver les Etats-Unis de combustible russe après les nouvelles sanctions de Washington, menaces qui ne se sont pas concrétisées.

Quelle rentabilité ?

Mais est-il rentable de relancer l'extraction de l'uranium aux Etats-Unis ? C'est loin d'être le cas pour le moment. Le combustible ne vaut plus que 22 dollars la livre sur le marché de gré à gré, on est presque revenu aux abîmes de 2016. Même le Kazakhstan qui a des coûts imbattables a réduit la voilure de sa production pour ne pas produire à perte.

Mais il est bon pour l'administration Trump à quelques mois des élections de mi-mandat aux Etats-Unis de faire miroiter de nouveaux emplois dans les mines américaines.

Le plus gros gisement d'uranium américain bientôt à la Cour suprême

Par Le Figaro.fr avec AFP Mis à jour le 21/05/2018

La Cour suprême à Washington a annoncé lundi qu'elle allait examiner la légalité d'une interdiction d'exploiter le plus gros gisement d'uranium connu aux Etats-Unis. La haute cour a ainsi entendu l'appel lancé par le gouvernement de Donald Trump, qui souhaite annuler cette interdiction prise par l'Etat de Virginie, où se trouve ce gisement.

En se justifiant par les inquiétudes sur le danger de pollution radioactive de ses cours d'eau, la Virginie avait prohibé en 1982 l'exploitation minière de ce grand gisement, découvert peu avant à proximité de sa frontière avec la Caroline du Nord. Mais les sociétés minières, propriétaires du gisement qu'elles estiment valoir 6 milliards de dollars, ont lancé une longue action judiciaire contre cette prohibition d'exploitation.

Elles affirment qu'à lui seul, l'uranium de ce site permettrait d'alimenter toutes les centrales nucléaires des Etats-Unis. Leur principal argument est que la décision d'exploiter une mine dépend selon elles des lois fédérales, notamment de l'Atomic Energy Act (AEA), et non des Etats. Le gouvernement de Donald Trump, qui a promis de dynamiser les mines en faillite du pays, a dans ce dossier épousé la cause des sociétés minières.

L' administration Trump c'est à dire le Department of Energy veux stopper une usine de reconversion de Plutonium militaire en combustible MOX qui était en construction en Caroline du Sud. Un gâchis à plus de 10 milliards de $
Billions of dollars later, Energy Department pulls plug on partly built nuclear fuel plant

The Energy Department's Savannah River site, which the Trump administration has decided not to complete, shown in January. (Reuters)

The Trump administration is pulling the plug on a South Carolina facility designed to convert weapons-grade plutonium into nuclear reactor fuel that the U.S. government has already spent billions to partially build.

Even though construction will end, the Trump administration wants to spend billions more to wind down the project and retrofit the plant for a new mission, namely, the production of triggers for nuclear weapons.

The decision marks the culmination of a years-long effort by both the Trump and Obama administrations to end construction of the plant, actions that the South Carolina delegation in Congress blocked, preserving a source of jobs and federal funding in their districts.

The original idea behind the facility near the Savannah River in Aiken, S.C., was to take tons of excess plutonium that the United States produced during the Cold War for nuclear weapons and convert the dangerous material into mixed-oxide, or MOX, fuel for commercial reactors. The United States signed a pact with Russia in 2000 agreeing to dispose of a certain amount of the Cold War-era fissile material from both countries, a deal that was seen as an arms-control milestone.

But since construction of the South Carolina facility began, the project has become mired in lawsuits, delays and budget overruns, emerging as a prime example of waste and mismanagement by the Energy Department’s National Nuclear Security Administration (NNSA). Meanwhile, relations between the United States and Russia soured, and Moscow pulled out of the pact in 2016, citing Washington’s noncompliance.
