GAO: NRC needs to do more to prepare for advanced reactor licensing

August 28, 2023, 12:00PMNuclear News

A Government Accountability Office report released last week on the Nuclear Regulatory Commission’s preparedness to review and approve advanced reactor applications finds—to scant surprise from nuclear advocates—room for improvement.

The 48-page report, Nuclear Power: NRC Needs to Take Additional Actions to Prepare to License Advanced Reactors, had been requested in February 2022 by two prominent Capitol Hill supporters of the technology—Sen. Shelley Moore Capito (R., W.Va.), ranking member of the Senate Environment and Public Works Committee, and Rep. Cathy McMorris Rodgers (R., Wash.), chair of the House Energy and Commerce Committee.

Kairos test reactor passes NRC safety review

June 28, 2023, 3:00PMNuclear News

The Nuclear Regulatory Commission staff has completed its final safety evaluation for Kairos Power’s application to build its Hermes advanced test reactor at a site in Oak Ridge, Tenn., the agency announced recently. The evaluation found no safety aspects precluding issuance of a construction permit for the proposed reactor.

NRC advisors give nod to Hermes construction permit

Having completed its review of the construction permit application for Kairos Power’s Hermes test reactor early last month, the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) recently submitted its conclusions to the agency, recommending approval.

NRC rejects hybrid approach to fusion regulation in a vote for clarity

April 19, 2023, 9:34AMNuclear News

The Nuclear Regulatory Commission announced on April 14 that it will regulate fusion energy systems using a framework based on the agency’s 10 CFR Part 30 process for licensing byproduct material facilities—such as particle accelerators—rather than 10 CFR Parts 50 and 52, which are used to license utilization facilities like fission power reactors. The commission’s decision means that future fusion energy facilities could be regulated by Agreement States acting with guidance from the NRC.

SHINE's final SER for Wisconsin facility issued by NRC

The Nuclear Regulatory Commission has issued its final safety evaluation report (SER) related to the operating license application for SHINE Technologies' large-scale medical isotope production facility, known as The Chrysalis, in Janesville, Wis. The SER documents the results of NRC staff’s technical and safety review of SHINE’s application. SHINE announced the NRC’s decision on February 27.

A record of decision concerning the proposed issuance of the operating license will be published by the NRC at a future date.

The enduring legacy of ACRS: Reviewing safety-licensing to protect the public

February 24, 2023, 3:03PMNuclear NewsHossein Nourbakhsh

The 1957 amendment to the Atomic Energy Act of 1954 established the Advisory Committee On Reactor Safeguards as a statutory committee with an independent advisory role and the responsibility to “review safety studies and facility license applications” and advise the U.S. Atomic Energy Commission “with regard to the hazards of proposed or existing reactor facilities and the adequacy of reactor safety standards.” With the enactment of the Energy Reorganization Act of 1974, the ACRS was assigned to the newly established Nuclear Regulatory Commission with its statutory requirements intact.

ACRS backs NuScale’s smaller, PRA-informed emergency planning zone

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.

Looking back at a Nuclear News Q&A

February 24, 2022, 3:07PMNuclear News

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.

The Advisory Committee on Reactor Safeguards elects 2022 leadership

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.

The origins of The Reactor Safety Study

In March 1972, Stephen Hanauer, a technical advisor with the Atomic Energy Commission, met with Norman Rasmussen, a nuclear engineering professor at the Massachusetts Institute of Technology. The AEC had recruited Rasmussen to develop a report, The Reactor Safety Study (WASH-1400), to estimate the probabilities and consequences of a major nuclear power plant accident. With thousands of safety components in a modern reactor, the task was mind-boggling. Rasmussen proposed a novel approach based on more powerful computers, “fault tree” methodology, and an expanding body of operational data. By calculating and aggregating probabilities for innumerable failure chains of components, he believed he could develop a meaningful estimate of overall accident risk. WASH-1400 would be a first-of-its-kind probabilistic risk assessment (PRA).

NRC looking to fill open ACRS position

September 9, 2021, 7:00AMNuclear News

The Nuclear Regulatory Commission is seeking qualified candidates for an open position on its Advisory Committee on Reactor Safeguards. The ACRS is an advisory group that provides independent technical review of, and advice on, matters related to the safety of existing and proposed nuclear facilities and on the adequacy of proposed reactor safety standards. It also advises the NRC on health physics and radiation protection issues.

Interested individuals can find candidate criteria and details in the Federal Register notice published on September 8 and available on the NRC’s website. Resumes will be accepted until December 7.

Resumes should be sent to Makeeka Compton and Jamila Perry, ACRS, Mail Stop T2B50, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, or e-mailed to Makeeka.Compton@nrc.gov and Jamila.Perry@nrc.gov.

More information on the ACRS is available on the NRC’s website.

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) has issued a report recommending approval of Dominion Energy’s 20-year subsequent license renewal (SLR) application for Surry-1 and -2. The board reached its conclusion during its April meeting, after reviewing both the SLR application and the associated final safety evaluation report. Dominion submitted the application in October 2018.
