NRC approves overhaul of FOF inspections, baseline security programs
The security drills held at commercial nuclear power plants as part of the Force-on-Force (FOF) inspection program will no longer be led by the Nuclear Regulatory Commission.
The commissioners on Friday approved recommendations presented earlier in the year by NRC staff to significantly overhaul the security program. This includes phasing out NRC-led drills by 2028. Following the phaseout, drills will be led by the licensee, with the NRC observing.
