Rep. Jeff Duncan (R., S.C.), a member of the House Energy and Commerce Committee, has issued a three-page “Blueprint for Nuclear Innovation and Competitiveness,” highlighting nuclear policy priorities in the areas of licensing and regulatory modernization, financing, and fuel (including used fuel). According to a press release from Duncan’s office, the document aims “to help chart the course for the nuclear energy agenda in the next Congress and facilitate policy discussions among both lawmakers and industry leaders.” Published last week—along with a related “Dear Colleague” letter—the blueprint is also, according to E&E News, “a sign of his ambitions for landing a more senior role with the committee,” including a subcommittee leadership position should the GOP gain control of the House in the next Congress.

Ontario’s advanced nuclear technology firm Terrestrial Energy yesterday announced the signing of a letter of intent (LOI) with TerraPraxis, a U.K.-based nonprofit devoted to climate solutions, to cooperate on the latter’s Repowering Coal initiative—a program aimed at integrating clean heat sources with existing infrastructure at coal-fired power plants in North America and elsewhere.

“There’s going to be a cliff”: Preparing an international SMR supply chain

Participating in the forum were (from left) John Hopkins (NuScale Power), Renaud Crassous (EDF), Daniel Poneman (Centrus Energy), Adriana Cristina Serquis (CNEA), and Boris Schucht (Urenco).

The nuclear industry leaders assembled in Washington, D.C., last week to discuss small modular reactor supply chains agreed that lost generation capacity from the expected retirement of hundreds or thousands of coal power plants over the next decade—a cliff, in one panelist’s words—represents an opportunity that developers of SMRs and advanced reactors are competing to meet.

“I think in total 80 projects are ongoing,” said Boris Schucht, panel moderator and chief executive officer of Urenco Group, as he opened the forum. “Of course not all of them will win, and we will discuss today what is needed so that they can be successful.”

Computer-Guided Work

When it comes to computer-guided navigation, we look to our GPS app for seamless guidance. It provides granular, step-by-step directions while it tracks our position and progress towards our destination. It superimposes relevant information such as the location of restaurants and the lowest price gas stations on route. One of these days, it will even read us the menu of a selected restaurant on our path while placing an order as we drive towards it.

Control Source Term Reduction Using Specialty Macroporous Resins

November 1, 2022, 11:22AMSponsored ContentPurolite

Managing plant source term for refueling outage cleanup and full power service can be controlled with the aid of specially macroporous resins. These ion exchange resins are often a cost-effective media for containing impurities in nuclear coolant, minimizing the release of contaminants and ionic leakage, all while encountering impact from oxidative chemistry and radiation. Macroporous resins continue to meet increased expectations in the industry and are considered among the best-accepted practices for nuclear plant source term minimization in standalone and layered polishing vessels.

Westinghouse to build Poland’s first nuclear reactors; KHNP may get separate deal

October 31, 2022, 3:00PMNuclear News

Morawiecki

Poland has chosen Westinghouse Electric Company to supply the reactors for its initial nuclear power plant, as the Central European nation seeks to lessen its dependence on domestic coal and Russian imports for its energy supply. On Friday, Polish prime minister Mateusz Morawiecki announced the decision on Twitter, confirming last week’s reports that Westinghouse’s AP1000 technology was the government’s likely choice.

“A strong [Polish-American] alliance guarantees the success of our joint initiatives,” Morawiecki tweeted. “After talks with [vice president Kamala Harris and energy secretary Jennifer Granholm], we confirm our nuclear energy project will use the reliable, safe technology of [Westinghouse].”

Competing with the American firm for the job were Électricité de France and Korea Hydro & Nuclear Power. In October 2021, EDF submitted an offer to build four to six EPRs in Poland, while KHNP offered in April of this year to construct six APR1400 units.

Risk insights map an efficient approach to aging management

October 28, 2022, 3:00PMNuclear NewsSusan Gallier

Any method that can enhance safety, reduce risk, and lower costs is worth a second look. When that method proves it has the potential to optimize aging management at any nuclear power plant, it’s time to spread the word.

In 2019, a small team focused on selective leaching began looking for a way to use risk insights to optimize the implementation of deterministic aging management programs (AMPs). What they started soon grew into a large team effort by Constellation, Ameren, the Electric Power Research Institute (EPRI), and the Nuclear Energy Institute (NEI), along with contractors Enercon and Jensen Hughes, to develop a generic framework and then test it in two very different pilot applications.

Canada Infrastructure Bank (CIB) has finalized an agreement with Ontario Power Generation, committing C$970 million (about $715 million) to Canada’s first small modular reactor, to be located at OPG’s Darlington nuclear power plant in Clarington, Ontario.

A state-owned enterprise founded in 2017, CIB is charged with financially supporting revenue-generating infrastructure projects in the public interest via public-private partnerships. The agreement with OPG is the bank’s largest investment in clean power to date, according to a Tuesday joint announcement.

Following a meeting in Washington, D.C., on Sunday with secretary of energy Jennifer Granholm, Polish deputy prime minister Jacek Sasin told reporters that his nation is close to choosing the reactor supplier for its initial nuclear plant project, adding, according to Bloomberg, “There is a big chance that we will finally pick Westinghouse.”

And in a news release on the meeting from the Polish government, Sasin is quoted as saying, “The massive energy crisis that is currently affecting us means that we must quickly make decisions on building the country’s energy security based on new, clean, cheap, and reliable sources, and such a source is nuclear energy. We want the decisive decisions to be made as soon as possible. That is why we asked [Granholm] for a meeting, during which we will clarify all the issues that remain to be clarified.”

NuScale Power announced October 20 that the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) issued a letter the previous day agreeing with NRC staff’s approval of NuScale’s methodology for determining the plume exposure pathway emergency planning zone (EPZ). As approved, the methodology would permit a smaller EPZ—dependent on site-specific conditions, including seismic hazards—that provides the same level of protection to the public as the 10-mile radius EPZs used for existing U.S. nuclear power plants.
