Daniel H. Dorman has been chosen as the Nuclear Regulatory Commission’s next executive director for operations, effective October 10. He succeeds Margaret M. Doane, who leaves the agency October 8 to take a senior position with the International Atomic Energy Agency.

Dorman currently serves as the NRC’s deputy executive director for reactor and preparedness programs, which includes oversight of all four of the agency’s regional offices.

“Dan has admirably served the NRC for more than 30 years in key leadership positions,” said NRC chairman Christopher T. Hanson. “He is someone who keenly understands the needs of our agency and our people. Dan is a problem solver, a champion for agency modernization and innovation, and has proven through results his ability to rally our staff for a common purpose. He has earned the respect of our workforce, the NRC leadership, and the agency’s diverse stakeholders.”

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.

Only a few of the more than 3,000 radioisotopes that scientists have synthesized in the laboratory are regularly used in diagnostic or therapeutic medicine. One significant barrier to the development of new medical radioisotopes is the difficulty of gaining access to radionuclides during the early stages of development and research. PRISMAP is a new medical radionuclide program designed to streamline that access for medical research in the European Union and the United Kingdom.

A proposal by PJM Interconnection to modify the Federal Energy Regulatory Commission’s contentious minimum offer price rule (MOPR) order went into effect by default on Wednesday after the commission failed to take action on it.

According to a notice from the FERC secretary, “In the absence of commission action on or before September 28, 2021, PJM’s proposal became effective by operation of law. Accordingly, the effective date of the proposed tariff sheets is September 29, 2021. The commission did not act on PJM’s filing because the commissioners are divided two against two as to the lawfulness of the change.”

Exelon Generation announced yesterday that it is investing more than $300 million in capital projects at its Byron and Dresden nuclear plants in Illinois over the next five years and filling some 650 vacant positions across the state.

These actions are in response to Illinois Gov. J.B. Pritzker’s recent signing of S.B. 2408, the hard-won legislation that rescued the nuclear facilities from premature retirement.

Florida Power and Light Company is seeking to keep its St. Lucie nuclear plant in operation into the 2060s, and so far, so good: In early August, the utility submitted to the Nuclear Regulatory Commission a subsequent license renewal application for the facility’s two units, and last Friday, the NRC accepted the application for review.

By 2030, Kairos Power aims to demonstrate electricity production from a full-scale, 140-MWe fluoride salt–cooled high-temperature reactor, the KP-X. In service of that goal, Kairos plans to demonstrate Hermes, a scaled-down 35-MWth nonpower reactor, in Oak Ridge, Tenn.

Hermes is being built to “prove our ability to deliver affordable nuclear heat,” said Mike Laufer, Kairos Power chief executive officer and cofounder, as he explained Kairos’s plans to the local community during a September 28 webinar now available to view on demand. Laufer took questions, and Kairos took the opportunity to introduce a virtual open house that visitors can tour to view videos and interactive features and even submit comments.

Bruce Power has received approval from the Canadian Nuclear Safety Commission (CNSC) to begin the production of lutetium-177, becoming the first power reactor globally to commercially produce the medical radioisotope. Isogen, a joint venture between Framatome and Kinectrics, will produce Lu-177 at Bruce’s eight-unit CANDU nuclear power plant in Ontario, Canada, using Isogen’s isotope production system (IPS).

In late January, after plans were scrapped for Wylfa Newydd—the Hitachi-led project to build two ABWR units at the site of the decommissioned Wylfa reactors on the Welsh island of Anglesey—the British government stated, “Wylfa remains an important site for potential new projects, and the U.K. government will continue to explore future opportunities for it.”

More than a dozen of the world’s leading nuclear industry executives have teamed up with the International Atomic Energy Agency to form the Group of Vienna, with the aim of using nuclear technologies to address global challenges, including climate change, disease, and hunger.

With the goal of providing basic information on advanced reactors to help the public and stakeholders understand the technology’s promise, the nonprofit think tank Nuclear Innovation Alliance has published Advanced Nuclear Technology: A Primer.

Canadian Nuclear Laboratories (CNL) announced on September 23 that it had refueled the SLOWPOKE-2 research reactor at the Royal Military College of Canada (RMC) in Kingston, Ontario. The reactor was recommissioned on September 10 after a 22-day outage.

Some of the major achievements of the nuclear safety cooperation agreement between the International Atomic Energy Agency and the European Union (EU) include more than 100 nuclear safety review missions, environmental remediation at former uranium sites in Central Asia, and more effective radioactive waste management in Africa.

Probabilistic risk assessment is a systematic methodology for evaluating risks associated with a complex engineered technology such as nuclear energy. PRA risk is defined in terms of possible detrimental outcomes of an activity or action, and as such, risk is characterized by three quantities: what can go wrong, the likelihood of the problem, and the resulting consequences of the problem.

Matthew Denman is principal engineer for reliability engineering at Kairos Power and the chair of the American Nuclear Society and American Society of Mechanical Engineers Joint Committee on Nuclear Risk Management’s Subcommittee of Standards Development. As a college student at the University of Florida, Denman took a course on PRA but didn’t enjoy it, because he did not see its connection to the nuclear power industry. Later, during his Ph.D. study at the Massachusetts Institute of Technology, his advisor was Neil Todreas, a well-known thermal hydraulics expert. Todreas was working on a project with George Apostolakis, who would leave MIT to become a commissioner of the Nuclear Regulatory Commission. The project, “Risk Informing the Design of the Sodium-Cooled Fast Reactor,” was a multi-university effort funded through a Department of Energy Nuclear Energy Research Initiative (NERI) grant. Todreas and Apostolakis were joined in this project by a who’s who of nuclear academia, including Andy Kadak (MIT, ANS past president [1999–2000]), Mike Driscoll (MIT), Mike Golay (MIT), Mike Lineberry (Idaho State University, former ANS treasurer), Rich Denning (Ohio State University), and Tunc Aldemir (Ohio State University).

To prevent future winter storms from causing the kind of widespread, lethal power outages wrought by February’s frigid blast through Texas and other states, the electric and natural gas industries need to bolster their winterization and cold weather preparedness and coordination, a just-released preliminary report from the Federal Energy Regulatory Commission and North American Electric Reliability Corporation concludes.

The two agencies had announced on February 16 that they planned to open a joint inquiry to identify problems with the performance of the bulk power system during the storm and to offer solutions. A team of FERC and NERC staff members presented the report at a FERC meeting on September 23.

A presentation of the report, February 2021 Cold Weather Grid Operations: Preliminary Findings and Recommendations, is available.

The staff of the Nuclear Regulatory Commission recently released a draft white paper outlining strategies for streamlining microreactor licensing. The paper is to be used to facilitate discussion at an upcoming advanced reactor stakeholder public meeting.

“This paper,” the document emphasizes, “has not been subject to NRC management and legal reviews and approvals, and its contents are subject to change and should not be interpreted as official agency positions.”
