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.

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.
River Bend nuclear power plant
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.

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.
The St. Lucie nuclear power plant.
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.
Explore Kairos Power’s plans in a virtual open house.
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).

Our next-generation leaders must begin to think more creatively, using risk-informed solutions to ensure safe, resilient, sustainable, and socially responsible technological advancements to usher in an era void of technological accidents. Probabilistic risk assessment (PRA) research and education provide nuclear engineering students with the scientific expertise and viable skill sets essential for meeting the growing demand for risk analysts in nuclear energy domains.
