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)

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.

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.

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.

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.

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.”
