The Nuclear Regulatory Commission (NRC) held a public meeting on August 8 to provide information and receive comments on the regulatory basis supporting the NRC’s rulemaking on physical security requirements for advanced reactors. The public meeting was the latest step in the NRC’s rulemaking process, which began on August 1, 2018, with the NRC Staff’s report to the Commission evaluating options for revising physical security regulations for advanced reactors. The Commission approved the NRC Staff’s proposed rulemaking plan on November 19, 2018. We previously reported on the NRC Staff’s report, the Commission’s Approval, and the publication of the regulatory basis for comment.
During the public meeting, NRC Staff summarized the regulatory basis and their recommendation for a limited-scope rulemaking. NRC Staff explained that the purpose of the rulemaking is to provide requirements and guidance for advanced reactor physical security and reduce the need for physical security exemptions—specifically from regulations requiring each site to have at least 10 armed responders for emergency security response (10 CFR § 73.55(k)(5)(ii)), and an on-site secondary alarm station to monitor potential issues (10 CFR § 73.55(i)(4)(iii)).
