Ils sont complètement inconscient aux US, ils perdent la main sur la production de l' Uranium sur leur propre sol, leur production à quasi zéro :
US uranium output falls 89% in 2019

19 May 2020

The USA produced a total of 0.17 million pounds U3O8 (65.4 tU) of uranium concentrate from all domestic sources in 2019, according to a newly published annual report from the US Energy Information Administration (EIA). This was 89% less than in 2018.

The 2019 Domestic Uranium Production Report recorded US uranium production in 2019 from six facilities: five in-situ leach (ISL) plants in Nebraska and Wyoming (Crow Butte Operation, Lost Creek Project, Ross CPP, North Butte, and Smith Ranch-Highland Operation) and one underground mine. At the end of the year, two conventional uranium mills - Shootaring Canyon Uranium Mill in Utah and Sweetwater Uranium Project in Wyoming - were on standby, and the White Mesa Mill in Utah was no longer producing uranium. The report does not provide details of the amount of ore fed to mills from underground mines, but notes that this may include ore mined and shipped to a mill during the same year, previously mined ore from stockpiles at mine sites, ore from stockpiles maintained at a mill site, or a combination of these.

At the year's end, three ISL plants - Lost Creek, Nichols Ranch ISR Project, and Smith Ranch-Highland, all in Wyoming - were operating with a combined capacity of 9.5 million pounds U3O8 per year, the EIA said. Six ISL plants were on standby.

Total employment in the US uranium production industry was 265 full-time person-years (one person year is equal to full-time employment for one person), a 29% year-on-year decrease. Employment in mining activities, at 48 person-years, was 56% down on the 110 person-years recorded for 2018, but exploration employment, at 40 person-years, showed a 48% increase.

Reported estimated US uranium reserves at the end of 2019 were 31 million pounds U3O8 at a maximum forward cost of up to USD30 per pound; 206 million pounds U3O8 at up to USD50 per pound and 389 million pounds U3O8 up to USD100 per pound.

"These reserves are a fraction of likely total domestic uranium reserves because we did not include inferred resources that were not reported because of a lack of cost estimates or because the reserves were not located on actively managed properties," the EIA said.

The Nuclear Fuel Working Group, established last year by the US Administration to analyse national security considerations with respect to the entire nuclear fuel supply chain, recently published a strategy to revive the USA's nuclear fuel cycle. In it, the group recognised the importance of taking "focused, deliberate action" to prevent the near-term collapse of the domestic uranium mining, milling and conversion industries. Its recommendations include establishing a uranium reserve, ending the Department of Energy's bartering of uranium and re-evaluating DOE's excess uranium inventory management policy.

La centrale de Indian Point dans la roue de celle de Fessenheim.

Le réacteur 2 de 998 MWe à fermé hier 30 Avril après 45 années d' opérations. le réacteur 3 de 1030 MWe va fermer l' an prochain en Avril.
Entergy closes Indian Point unit 2

30 April 2020

Unit 2 of Entergy's Indian Point nuclear power plant will be shut down for the final time today after more than 45 years of operation. Unit 3, the remaining operating unit at the site in the state of New York, is scheduled to be permanently shut down by this time next year.

"Over the last 45 years, thousands of dedicated professionals have operated Unit 2 at Indian Point - safely, securely and reliably," Entergy Chief Nuclear Officer Chris Bakken said. "We owe each of them our thanks for a job well done and for their commitment to the highest standards of professionalism."

The two-unit plant is in the south-east of New York state, 24 miles (39 kilometres) from New York City. Unit 2 - a pressurised water reactor (PWR) which has a net generating capacity of 998 MWe - began commercial operation in August 1974 and unit 3 - a 1030 MWe (net) PWR - two years later.

The plan to shut down the reactors was announced by Entergy in 2017 and is pursuant to a settlement agreement with the State of New York. This was the result of a number of factors, including sustained low current and projected wholesale energy prices that reduced revenues, the company said yesterday. The agreement included a provision that in the event of an emergency situation affecting electricity generation, the state may agree to allow the plant to continue operating for up to five more years. Indian Point 2 is currently licensed to operate until 2024 and unit 3 until 2025.

Assistant secretary for the US Department of Energy Office of Nuclear Energy Rita Baranwal, who had previously tweeted that the premature shutdown of Indian Point "pained" her, said it was "disappointing" to see unit 2 shut down four years prior to the expiry of its operating licence.

"As recently highlighted in the Nuclear Fuel Working Group report, nuclear power is a crucial component of our energy infrastructure that provides reliable, clean energy to our grid," she said, adding that the region will not only lose 1000 megawatts of clean and reliable power this year, but millions of dollars in local tax revenues and hundreds of high-paying jobs when unit 3 shuts down next April. "Our nation's reactors, which can run up to 80 years, should be allowed to safely run out their lifespan. The Office of Nuclear Energy is committed to preserving the US fleet and will continue working directly with industry to support research that reduces operating costs, increases revenue opportunities and keeps our largest source of clean energy on the grid for many more years to come," Baranwal said.

Then, in an April 17 letter, 21 GOP House members urged the administration to open up public lands where mining of critical minerals is currently banned, including the Breccia Pipe Uranium formation near the Grand Canyon.

"Keeping this valuable resource off limits does not make economic or environmental sense and puts our long-term energy security at risk," they wrote.

Amber Reimondo, energy program director for the Grand Canyon Trust, said Four Corners ore contains uranium concentrations that are relatively low, close to 1 percent, compared to concentrations from suppliers in Canada and Australia

Trump administration unveils plan to rescue US uranium mining

Jackson Chen | April 23, 2020

The Trump administration released a report on Thursday outlining its plan to revitalize the US nuclear energy industry and support domestic uranium mining amid concerns that the nation has lost its spotlight on the global nuclear technology stage.

The report was compiled by the Nuclear Fuel Working Group — a task force appointed by President Donald Trump in July to undertake a detailed analysis of the US nuclear fuel supply chain — and submitted to the US Energy Department.

The report made several key recommendations to the US government, including streamlining the permitting process for public land access, making it faster and easier to mine uranium — an essential mineral for nuclear power.

For miners, notable recommendations include making direct purchases of 17 to 19 Mlb of U3O8 to establish a uranium reserve beginning in 2020, which would provide direct support to the front end of the fuel cycle and support the operation of at least two US uranium mines.

The report also includes President Trump’s earlier request to Congress for a uranium reserve and a $1.5 billion budget over 10 years to make direct purchases from domestic producers.

Republican lawmakers and uranium producers have long called for measures to boost US uranium mining and the nuclear energy industry, which the report says was at “high risk of insolvency.”

Over recent years, US nuclear power producers and uranium miners have suffered from a lack of investment and support. Last year, Trump rejected a request by the county’s top two uranium producers Energy Fuels and Ur-Energy seeking 25% purchasing quotas for domestic uranium output.

The report also recommended extending an agreement to limit Russian uranium imports as well as denying imports from China, and funding research and development on new types of reactors and fuels.

Secretary of Energy Dan Brouillette said the report contains a “road map for what we think needs to be done to not only revitalize but re-establish American leadership in this entire industry.”

He added that it is possible for Trump to issue executive orders to support the findings of the report.

However, opponents of the government’s efforts to bolster the nuclear sector are concerned these recommendations would increase mining near national parks and harm public health. Some also argue that the nation already supplies uranium at competitive prices, and the government has attempted similar endeavours to save the coal industry.

US companies currently provide only 10% of the domestic uranium purchases, with more than 60% of supplies imported from allies like Canada, Australia and Kazakhstan.

Trump administration seeks $1.5 billion to revive uranium mining

SALT LAKE CITY (AP) February 14, 2020

The Trump administration is asking Congress for $1.5 billion over 10 years to create a new national stockpile of U.S.-mined uranium, saying that propping up U.S. uranium production in the face of cheaper imports is a matter of vital energy security.

But some Democratic lawmakers, and market analysts across the political spectrum, charge that the Trump administration's overall aim is really about helping a few uranium companies that can't compete in the global market. Demand for the nuclear fuel has languished worldwide since Japan's 2011 Fukushima disaster. U.S. uranium production has plummeted 96% in the last five years, the U.S. Energy Information Administration reported Thursday.

The U.S. nuclear industry has sought help from the Trump administration, including asking for taxpayer subsidies to promote use of U.S. uranium. U.S. nuclear power plants in 2018 got 90 percent of their uranium from Canada, Kazakhstan and other foreign suppliers, and only 10 percent from U.S. mines.

Moore said the program should lead to production of 2.5 million pounds of uranium per year. U.S. uranium mines produced less than 174,000 pounds in 2019, according to Thursday's Energy Information Administration report. That's down from 4.9 million pounds in 2014.

Les USA veulent se constituer une réserve stratégique d' Uranium en U3O8 et y consacrer 150 millions de dollars chaque année de 2021 à 2030.
US uranium reserve proposal receives positive response

13 February 2020

US uranium companies have responded favourably to the Administration's 2021 budget request of USD150 million in funding to set up a uranium reserve. Energy Fuels CEO and President Mark Chalmers said the development was "an important step toward addressing the devastating impact of our nation's overdependence on uranium imports from Russia and its allies, which is displacing free market uranium and forcing US mines out of business".

In the budget request, which was unveiled on 10 February, the US Department of Energy (DOE) said the reserve would be part of efforts to help "re-establish" the USA's nuclear fuel supply chain through the domestic production and conversion of uranium. According to DOE, it reflects the priorities of the Nuclear Fuel Working Group (NFWG) which was set up following a July 2019 presidential decision in response to a Section 232 Petition from two US uranium miners, Energy Fuels Inc and Ur-Energy.

Energy Fuels is the owner of the White Mesa mill in Utah which is the only operating conventional uranium mill in the USA, as well as in-situ leach (ISL) projects at Nichols Ranch in Wyoming and Alta Mesa in Texas. "[W]e believe we are well-positioned to provide a significant portion of the uranium needed for the reserve … and we are able to commence ramping up production immediately," Chalmers said.

Wayne Heili, managing director and CEO of Australia-based Peninsula Energy, said around 2 to 3 million pounds U3O8 (769-1154tU) of US-mined uranium, depending on price, would be required for the reserve's initial purchases. Peninsula, which owns the Lance uranium project in Wyoming, "stands ready to provide uranium to help meet the strategic needs of the United States", he said.

Azarga Uranium Corp President and CEO Blake Steele said the annual USD150 million request to establish the strategic reserve would equate to USD1.5 billion between 2021 and 2030. The company is continuing to "de-risk" the advanced-stage Dewey Burdock ISL project in South Dakota, and "anticipates being well positioned to realise the benefits of the Administration's support of the United States nuclear industry", he said.

Vancouver-based Anfield Resources has 25 Wyoming-based uranium projects including the advanced Charlie project, for which it completed a preliminary economic assessment last September. The company said it is "well-positioned" to contribute to the reserve. Anfield CEO Corey Dias said the proposal to create a strategic uranium reserve was a "critical first step" to provide US producers with a "dedicated, improved domestic market" for their material. "Moreover, the NFWG may have additional recommendations on which the Administration might act that could further improve the prospects of US-based uranium miners and producers," he said.

The proposed budget is subject to appropriation by the US Congress.

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.”
