An ANS virtual event titled "Perspectives from Past NRC Chairs" featured four former members of the Nuclear Regulatory Commission who focused on the future of nuclear energy in the United States and the NRC’s role as a regulator of small modular and advanced reactors.

The virtual event gave us an idea for #ThrowbackThursday to search through the Nuclear News archives (available to all ANS members) for an interview with George Apostolakis, published in the March 2000 issue. At the time, Apostolakis was a professor at the Massachusetts Institute of Technology and a member of the NRC’s Advisory Committee on Reactor Safeguards. Ten years later, he was sworn in as an NRC commissioner.

Framatome announced on February 22 that the Nuclear Regulatory Commission has approved a license amendment that would allow Framatome’s shipping containers to transport, in the United States, fresh nuclear fuel assemblies containing uranium enriched up to 8 percent uranium-235.

Light water reactor fuel with higher enrichments and burnup capabilities than currently used under low-enriched uranium regulation could improve electricity generation and fuel utilization, possibly improving plant economics and providing more flexible reactor performance through extended operating cycles and more efficient core configurations.

The Nuclear Regulatory Commission has proposed a $7,000 fine to Marian Medical Services (MMS), of Wildwood, Mo., for four violations of regulatory requirements related to its licensed activities in Anchorage, Alaska. The violations involved the company’s failure to properly handle, store, and secure five sealed sources that it was licensed to use at its Anchorage medical clinic to perform diagnostic imaging services.

According to an NRC report, the clinic was licensed in 2016 but stopped offering nuclear medicine services in 2018 because there weren’t enough patients to sustain the business.

Today’s #ThrowbackThursday post looks at the initial debate surrounding the conversion of research reactor fuel from high-enriched uranium to low-enriched uranium. An article published in the April 1984 issue of Nuclear News (available to all ANS members), titled “NRC studies HEU-to-LEU fuel conversion issue,” was written by the ANS Washington editor John Graham, and brings up several items of interest.

The story: Graham introduces the readers to the growing security concerns around HEU and notes that the issue has its roots in the nonproliferation concerns from the Carter administration that forced the domestic nuclear industry to abandon certain projects—the subject of a #TBT post a couple of weeks ago.

The Nuclear Regulatory Commission has denied a petition for rulemaking, filed in February 2019 by Gerard P. Van Noordennen on behalf of EnergySolutions, requesting that the agency revise its regulations to allow licensees access to a nuclear power plant’s decommissioning trust fund to pay for the disposal of major radioactive components before the plant permanently ceases operations and begins decommissioning.

“Major radioactive components” refers to the reactor vessel and internals, steam generators, pressurizers, large bore reactor coolant system piping, and other large components.

Westinghouse Electric Company and Southern Nuclear have agreed to a plan to install four Westinghouse lead test assemblies in Vogtle-2, a 1,169-MWe pressurized water reactor located in Waynesboro, Ga. Four lead test assemblies containing uranium enriched up to 6 percent U-235 will be loaded in Vogtle-2 in 2023, marking the first time that fuel rods with uranium enriched above 5 percent U-235 are put in use in a U.S. commercial power reactor.

The Nuclear Regulatory Commission has issued a confirmatory order to Holtec Decommissioning International (HDI) following an alternative dispute resolution mediation session regarding security-related violations at the Oyster Creek nuclear power plant in Lacey Township, N.J. A subsidiary of Holtec International, HDI is decommissioning Oyster Creek, which permanently ceased operations in 2018.

The Nuclear Regulatory Commission will continue work on a new rule on security requirements for independent spent fuel storage installations (ISFSIs), with two of the agency’s three commissioners voting to disapprove a request by NRC staff to discontinue the proposed rulemaking. The commissioners’ votes on the request were recorded on August 4, 2021, but were not made public until January 24.

During a tour last week of the Tennessee Valley Authority’s two-unit Watts Bar nuclear power plant in Tennessee, Gov. Bill Lee said, "Nuclear energy is so important not only because it is an important part of TVA's power generation but also because of the value that clean energy via nuclear energy can have for sustainability in this country,” according to an article in the Chattanooga Times Free Press.

Lee added that he would support TVA’s plans if it decided to build small modular reactors.

The American Nuclear Society has just published ANSI/ANS-55.1-2021, Solid Radioactive Waste Processing System for Light-Water-Cooled Reactor Plants. The standard was originally issued in 1979 with a revision in 1992 to provide design guidance for in-plant solid radwaste systems.

Doriot

Koch

A new bill in the Indiana state Senate creates guidelines for state regulators to consider small modular reactors should utilities want to build them. Senate Bill 271 was sponsored by Sen. Eric Koch (R., Bedford), chair of the Senate Utilities Committee, and Sen. Blake Doriot (R., Goshen). Supporters of the bill said that SMRs could replace retiring coal plants and would supplement renewables.

The Indy Star reported on January 24 that the utilities committee passed the bill by a vote of eight to two and that it now heads to the full Senate.

In this first installment of a #ThrowbackThursday post, Nuclear News provides a review of radioisotope-powered pacemakers in response to an article in The Wall Street Journal. The article, published earlier this week, looks at the issue of disposing of nuclear-powered pacemakers, although considering how few are still in use today, it seems like this is really much ado about nothing.

Clark

The Nuclear Regulatory Commission announced today the selection of Brooke Poole Clark as the new secretary to the Commission, effective spring 2022. Clark will replace Annette Vietti-Cook, who is retiring after nearly 40 years of service at the NRC.

In her new position, Clark will provide executive management services to support the Commission and implement Commission decisions. She will be responsible for scheduling Commission meetings, managing the Commission's decision-making process, codifying Commission decisions in memoranda, processing and controlling Commission correspondence, and maintaining the Commission's historical records collection, among other tasks.

The Nuclear Regulatory Commission has denied “without prejudice” Oklo Power’s application to build and operate its Aurora microreactor in Idaho, the agency announced yesterday. The denial, according to the NRC, is due to the California-based firm’s failure to provide sufficient information on several crucial topics regarding the Aurora design.

Rempe

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards has elected Joy Rempe as chair, Walter Kirchner as vice chair, and David Petti as member-at-large. All three are ANS members.

“I am honored that my colleagues on the ACRS elected me to this position,” said Rempe, of Rempe and Associates. “The leadership team looks forward to ensuring that the ACRS continues its tradition of providing the commission advice on safety issues.”

Bios: Rempe has more than 35 years of experience in the areas of reactor safety and instrumentation performance. Prior to retiring as a Laboratory Fellow at Idaho National Laboratory, she founded an instrumentation development and deployment laboratory, which supported irradiation testing in U.S. and international facilities.
