GAO Report Released: Nuclear Regulatory Commission: Oversight and Status of Implementing a Risk-Informed Approach to Fire Safety
by Taryn Rucinski
Why GAO Did This Study
In
1975, a fire at a nuclear power plant damaged critical control cables
and hampered operators' ability to monitor the status of the plant's
reactor. NRC subsequently issued deterministic fire safety regulations
for plants to follow, but differences in plant design, coupled with
changes in NRC guidance, made it difficult for most plants to meet the
regulations without seeking numerous exemptions. In 2004, NRC issued a
regulation permitting plants to voluntarily transition to risk-informed
fire protection requirements. This new approach mirrors NRC's efforts to
adopt a more risk-informed regulatory approach to nuclear safety in
general. In 2008, GAO reported on three key fire safety issues and
recommended NRC take action to address them.
GAO
was asked to examine (1) NRC's progress in resolving the long-standing
fire safety issues raised in GAO's 2008 report at plants remaining under
the deterministic approach and at those plants transitioning to the
risk-informed approach; (2) the potential benefits of transitioning to a
risk-informed approach and the basis for NRC's decision to make
adoption of this approach voluntary; and (3) challenges, if any, in
efforts to transition to a risk-informed approach in regulating fire
safety. GAO reviewed documents; analyzed responses from operators at a
nonprobability sample of 12 nuclear plants and from nine consultants or
academic experts on fire safety issues and risk-informed regulations;
and interviewed NRC, industry, and public interest group
representatives.
GAO is not making recommendations in this report. NRC found the report to be accurate and complete.
Recently, the Government Accountability Office (GAO) released a report, titled Nuclear Regulatory Commission: Commission Oversight and Status of Implementing a Risk-Informed Approach to Fire Safety GAO-18-8 (Oct. 22, 2012). The details of the 40-page report, available here, are discussed below:
