The U.S. Army Corps of Engineers announced on August 28 that it has awarded a contract worth about $68 million to the joint venture APTIM AECOM Decommissioning, of Alexandria, Va., for the decommissioning, dismantling, and disposal of the deactivated SM-1 nuclear power plant.

SM-1, located at Fort Belvoir in Fairfax County, Va., was the U.S. Army’s first nuclear reactor and the first facility in the United States to provide nuclear-generated power for a sustained period to the commercial grid.

Decommissioning crews are expected to begin mobilizing in early 2021, and the work is anticipated to take about five years to complete, according to the USACE.

The Bulletin of the Atomic Scientists (BAS) is currently featuring on its website a series of five articles by young American and Russian scholars on nuclear safety, with a focus on the industry’s three major accidents: Three Mile Island, Chernobyl, and Fukushima.

In one of those articles, “Don’t let nuclear accidents scare you away from nuclear power,” the authors conclude that “even after accounting for both the immediate and long-term toll of the three accidents, nuclear power has a remarkably safe track record compared to coal, natural gas, and even hydroelectric power.”

Registration is open for the American Nuclear Society’s first Virtual Career Fair, to be held September 22-23.

The final safety evaluation report for NuScale Power’s small modular reactor design has been issued, completing the design’s technical review and approval, the Nuclear Regulatory Commission announced on August 28.

The NRC will now prepare a rulemaking to certify the NuScale design. Full certification, if granted by the commissioners following the staff’s recommendation, will allow a utility to reference the design when applying for a combined license to build and operate a nuclear power plant.

The NuScale design is the first SMR to receive NRC design approval.

The flurry of public statements issued in reaction to last Thursday’s news regarding Exelon’s decision to prematurely retire its Byron and Dresden nuclear power plants includes one from an organization representing the North America’s Building Trades Unions (NABTU).

Nuclear energy is faced with a number of challenges in a changing energy landscape, driven by the need to reduce carbon emissions to mitigate climate change. Renewable energy technologies are being considered as the solution to climate change and are increasingly being deployed across the world. However, renewable energy sources, particularly solar and wind, are highly variable, and deployment of these technologies has resulted in significant perturbances in the energy market, raising questions about grid stability and the adaptability of other sources to compete in a changing marketplace that prioritizes renewables. Nuclear plants, well suited for baseload operation, have demonstrated technical capability and flexibility to respond to the fluctuating demand; however, they have also discovered that the economics of such operating mode are not necessarily optimal to their financial security. On the other hand, despite contributing to the carbon emissions, the low cost of abundantly available natural gas and resultant low-cost electricity have exacerbated the economic pressure on nuclear technologies, raising questions about their survival and role in future energy systems¹.

The government of Australia’s New South Wales (NSW)—a coalition of the Liberal and National parties—has decided against throwing its support behind a bill to repeal the state’s 30-plus-year ban on uranium mining, despite earlier reports suggesting otherwise.

Idaho National Laboratory’s Transient Reactor Test Facility, also known as TREAT, returned to service in 2017 after a hiatus of more than two decades. To make full use of TREAT’s capabilities, researchers at INL created the Minimal Activation Retrievable Capsule Holder (MARCH) test vehicle system, which, according to an August 26 Department of Energy press release, can cut years off the development process for nuclear fuels and materials and allow new clients, like NASA, to take advantage of TREAT’s capabilities.

Noting that both presidential candidates are opposed to the Yucca Mountain repository project in Nevada, David Klaus writes in the Bulletin of Atomic Scientists that “it is time for everyone else to accept that Yucca Mountain is finally off the table, and for the United States to begin to seriously consider realistic alternatives for safely managing the more than 80,000 tons of spent nuclear fuel currently sitting at 72 operating and shutdown commercial nuclear reactor sites across the country.”

Exelon Generation, operator of the largest nuclear reactor fleet in the United States, intends to downsize that fleet next year by retiring its Byron and Dresden plants. In an announcement released early this morning, Exelon said that the two-unit Byron, located near Byron, Ill., would be permanently closed in September 2021, followed in November by the two-unit Dresden, located in Morris, Ill.

Byron is licensed to operate for another 20 years; Dresden, a much older facility, is licensed for another decade.

The American Nuclear Society is offering a members-only webinar on Wednesday, September 2, at 1:00 p.m. (EDT) on the topic of “Black Racial Justice in the Nuclear Community.”

A panel of ANS members will discuss racial justice and share experiences through their personal and professional roles.

The webinar will be the first of a series of actions organized by the Diversity and Inclusion in ANS Committee (DIA).

Registration is required for the webinar.

In actions related to its rules involving employee protection, the Nuclear Regulatory Commission on August 24 issued a proposed civil penalty of $606,942 to the Tennessee Valley Authority, as well as an order prohibiting a senior TVA executive from NRC-licensed activities for five years and a violation notice to a second executive.

Following investigations completed in October 2019 and January 2020, the NRC concluded that two former TVA employees had been subjected to reprisals for raising concerns regarding a chilled work environment.

A team led by Bechtel National Inc. (BNI) that includes GE Hitachi Nuclear Energy (GEH) and TerraPower is in contract negotiations with Battelle Energy Alliance (BEA) for the design-and-build phase of the Versatile Test Reactor, BEA announced on August 24. As planned, the VTR would support irradiation testing of fuels, materials, and equipment designed for advanced reactors.

With the support of the European Nuclear Education Network, the Nuclear Energy Agency (NEA) is hosting an online event on August 27, at 7 a.m. EDT (1 p.m. in Paris).

The event will celebrate and recognize the accomplishments of the graduating classes of 2020 and 2021, especially those within the nuclear science and technology fields.

The event is free and open to all. Registration is required.

High winds that caused damage across central Iowa last week have prompted NextEra Energy to close the Duane Arnold nuclear power plant about two months earlier than originally planned. The plant’s 622-MWe boiling water reactor has been off line since August 10, when a line of intense, fast-moving windstorms, called derechos, caused a loss of off-site power and damaged the plant’s cooling towers. NextEra had planned to permanently shut down Duane Arnold, Iowa’s only nuclear power reactor, on October 30.

Global nuclear power generation in 2019 totaled 2,657 TWh, second only to the 2,661 TWh generated in 2006, according to the World Nuclear Performance Report 2020, released yesterday by the World Nuclear Association. This is the seventh consecutive year that nuclear generation has increased, the WNA noted, with output 311 TWh higher than in 2012.

“In 2020, the world’s nuclear reactors have shown resilience and flexibility, adapting to changes in demand while ensuring stable and reliable electricity supplies,” said WNA Director General Agneta Rising.

All six commissioners from Ohio’s Lake and Ottawa counties—home to the Perry and Davis-Besse nuclear plants—joined forces last week to express their opposition to an immediate repeal of the Ohio Clean Air Program Act (H.B. 6), which was tainted by last month’s scandal involving former Ohio Speaker of the House Larry Householder and four associates.

Signed into law by Ohio Gov. Mike DeWine in July last year—rescuing Perry and Davis-Besse from premature closure—H.B. 6 has become the subject of multiple calls for repeal since Householder’s July 21 arrest, including one from DeWine himself.

The Department of Energy on August 19 announced several awards to research teams applying artificial intelligence and machine learning to fusion energy. The planned total funding of $21 million is targeted at projects with time frames of up to three years; $8 million in fiscal year 2020 funding has already been committed to the work. Delivery of the balance-of-project funding will depend on future congressional appropriations.

“These awards will enable fusion researchers to take advantage of recent rapid advances in artificial intelligence and machine learning,” said Chris Fall, director of the DOE’s Office of Science. “AI and ML will help us to accelerate progress in fusion and keep American scientists at the forefront of fusion research.”

The Generation IV International Forum (GIF) is hosting a free webinar on August 26 on the topic of “Molten Salt Reactor Safety Evaluation—A U.S. Perspective.”

The webinar, which is intended for policy makers, managers, regulators, students, and the general public, will start at 8:30 a.m. (EDT). Registration is required.

Kazatomprom, Kazakhstan’s state-owned uranium production company, will continue “flexing down” production by 20 percent through 2022, compared to the planned levels under subsoil use contracts, the company announced last week. It will also maintain its 20 percent reduction against subsoil use contracts in 2021, with no additional production planned to replace volumes lost in 2020 due to measures taken to combat COVID-19.

Kazatomprom does not expect to return to full subsoil use contract production levels until a sustained market recovery is evident and demand and supply conditions signal a need for more uranium, the company noted.
