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 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).

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.
