The expected early retirement of a massive coal plant in Pueblo County, Colo., has the county commissioners mulling small modular reactors as a power source replacement.

The plant in question is Xcel Energy’s three-unit Comanche Generating Station, Colorado’s largest single source of greenhouse gas emissions. In 2018, Xcel received approval from the Colorado Public Utilities Commission (PUC) to retire Units 1 and 2 in 2023 and 2025, respectively. And earlier this year, the company filed a proposal to close the much newer Unit 3 in 2039—three decades earlier than expected. (Xcel also plans to run the unit at only 33 percent, beginning in 2030.) Meanwhile, environmental groups have been pushing for the closure of Unit 3 by the end of the decade.

The United Kingdom has announced a shortlist of five sites as the potential future home of the U.K. Atomic Energy Authority’s (UKAEA) prototype fusion energy plant, the Spherical Tokamak for Energy Production (STEP). A final decision on the plant’s location is to be made by the U.K.’s secretary of state for business, energy and industrial strategy around the end of 2022.

The Canadian Nuclear Safety Commission has approved the renewal of the site preparation license for Ontario Power Generation’s Darlington new-build nuclear project. First granted in 2012, the license is now valid until October 11, 2031.

Here is a recap of industry happenings over the course of the past month:

ADVANCED REACTOR MARKETPLACE

Ukraine’s Energoatom signs deals for nuclear power exploration and deployment

Energoatom, the state-owned nuclear utility of Ukraine, and Westinghouse Electric Company have signed an agreement to bring Westinghouse AP1000 reactors to multiple sites in Ukraine. The signing took place at the U.S. Department of Energy headquarters in Washington, D.C., and was witnessed by Ukraine’s president Volodymyr Zelensky, U.S. energy secretary Jennifer Granholm, and Ukraine’s energy minister German Galushchenko.

In addition, Energoatom signed a memorandum of understanding with NuScale Power to explore small modular reactor deployment in Ukraine. Under the MOU, NuScale will support Energoatom’s examination of NuScale’s SMR technology, including a feasibility study for proposed project sites and the development of a project timeline and deliverables, cost studies, technical reviews, licensing and permitting activities, and project-specific engineering studies and design work.

Kevin Marsh, former chief executive officer and chairman of the board of directors of SCANA Corporation, has become the first person to be sentenced to prison for involvement in the 2017 collapse of the $10 billion Summer nuclear plant expansion project. Marsh was sentenced in federal court on October 7 and in state court on October 11.

The failure to complete the construction of two Westinghouse AP1000 reactors at the single-unit nuclear plant in Jenkinsville, S.C., cost ratepayers and investors billions, damaged the brands of then owners SCANA and Santee Cooper, and put some 6,000 people out of work.

Canada’s Bruce Power, operator of the eight-unit Bruce nuclear power plant in Kincardine, Ontario, is undertaking a series of environmental initiatives to help attain its goal, announced in March, to achieve net-zero greenhouse gas emissions from site operations by 2027.

The Minerals Council of Australia (MCA) last week released Small Modular Reactors in the Australian Context, an overview of SMRs, their potential role in Australia, and their likely operating costs.

The 36-page report, written by Australian nuclear energy advocate Ben Heard, takes a look at three of the most advanced SMR designs currently undergoing regulatory approval: NuScale’s Power Module, GE-Hitachi’s BWRX 300, and Terrestrial Energy’s Integral Molten Salt Reactor.

The Department of Energy has released its 2021 Climate Adaptation and Resilience Plan, outlining steps that it will take to ensure its facilities and operations adapt to and are increasingly resilient to the impacts of a changing climate. As announced by the White House last week , the DOE was one of more than 20 federal agencies to release climate change plans, which were developed in response to President Biden’s executive order on tackling the climate crisis, issued in January.

Some 200 Polish business leaders gathered in Warsaw earlier this month to discuss local supply chain opportunities with two U.S. companies hoping to become major players in Poland’s nascent civil nuclear power program.

The companies, Westinghouse and industry partner Bechtel, hosted their second nuclear supply symposium on October 5, touting Westinghouse’s AP1000 reactor technology.

Arizona Public Service is the latest nuclear utility with confirmed plans to install hydrogen production capacity, an investment decision that is based on analysis conducted under the Department of Energy’s H2@Scale program and backed by a $20 million DOE award.

The Hungarian office of Framatome this week signed a memorandum of understanding with Budapest-based research and economic development company Hunatom and the University of Dunaújváros to work together supporting nuclear education and training, research and development, and implementation of new technologies for Hungary and surrounding countries.

Representatives of the three organizations signed the MOU during a ceremony at Hungary’s University of Dunaújváros, about 40 miles south of Budapest.

Low-altitude radiation survey flights over downtown Boston and the Boston Marathon race route will take place from Friday, October 8, through Monday, October 11, by a team from the National Nuclear Security Administration.

The surveys to be done using the NNSA’s Aerial Measuring System (AMS) are what the agency calls “a normal part of security and emergency preparedness activities.”

More information and video footage of the NNSA’s aerial assessments are available online.

The Nuclear Regulatory Commission is relinquishing its licensing authority for exports of deuterium for nonnuclear use to the Department of Commerce’s Bureau of Industry and Security. The NRC said that the change reflects the growing peaceful use of deuterium, including heavy water, as well as deuterium gas and deuterium or deuterated compounds, for nonnuclear industrial and research activities.

Duckworth

A bipartisan quartet of senators last week reintroduced legislation aimed at protecting employees of the Department of Energy and the Nuclear Regulatory Commission who report nuclear safety violations.

The bill—straightforwardly titled the Department of Energy and Nuclear Regulatory Commission Whistleblower Protection Act (S. 2896)—is sponsored by Sen. Tammy Duckworth (D., Ill.) and cosponsored by Sens. Chuck Grassley (R., Iowa), James Lankford (R., Okla.), and Ron Wyden (D., Ore.). Duckworth had introduced the legislation twice before, in May 2018 and May 2019.

The National Institute of Standards and Technology (NIST) has submitted two reports and supplemental information to the Nuclear Regulatory Commission after conducting a root cause analysis of the February 2021 fuel failure and resultant alert at the NIST Center for Neutron Research (NCNR) in Gaithersburg, Md. While the 20-MWt NCNR research reactor remains shut down, scuttling the plans of researchers who rely on it as a source of both cold and thermal neutrons, NIST states in an October 4 update that it has requested permission to restart the reactor, contingent upon meeting all 18 corrective actions identified.

Therapeutic radiation is typically reserved for cancer treatment, but scientists at Washington University School of Medicine in St. Louis have applied radiation therapy to treat ventricular tachycardia, a life-threatening heart arrhythmia. A news release issued by the university says that the results of the study show that radiation therapy can “reprogram” heart muscle cells to “a younger and perhaps healthier state.” The findings were published in the journal Nature Communications on September 24.

Canadian Nuclear Laboratories (CNL) last week issued a call for proposals for the third round of its Canadian Nuclear Research Initiative (CNRI) program.

More information about the program, including application details, can be found online.

The first of eight 160-ton steam generators for Unit 6 at Canada’s Bruce nuclear power plant was installed last week as part of the facility’s major component replacement project. “Congrats to the MCR team and our partners, including @AeconGroup, @Framatome_CA, @UEandC, @mammoetglobal, @BWXT, and others who contributed to this historic moment,” Bruce Power tweeted on September 30.

The component was fabricated at BWXT Canada’s Cambridge, Ontario, location and was shipped to the Bruce site in late 2020, as shown in this video.

The vendor responsible for generator removal is the Steam Generator Replacement Team (SGRT), a 50-50 joint venture between Aecon and the Steam Generating Team, itself a partnership between Framatome and United Engineers & Constructors. In July, Framatome announced that SGRT had been awarded an approximately C$350 million (about $278 million) contract by Bruce Power to replace the steam generators at Units 3 and 4.

The Nuclear Regulatory Commission has proposed a $150,000 fine to Entergy Operations after conducting investigations that identified three willful violations of agency requirements at the company’s River Bend nuclear power plant. Located in Francisville, La., River Bend houses a 974-MWe boiling water reactor.

Citing national security interests, the Nuclear Regulatory Commission has issued an order suspending the general license authority to export radioactive material and deuterium to China General Nuclear (CGN) and its subsidiaries or related entities.

The NRC licensees subject to the order had been authorized to ship radioactive materials and heavy water to China through a general license granted in sections 110.21 through 110.24 of 10 CFR Part 110. Notice of the order was published in the October 1 Federal Register.
