NRC staff proposes ROP, security inspection overhauls
The Nuclear Regulatory Commission staff is recommending proposed changes for the Reactor Oversight Process (ROP) baseline inspection program that could reduce the number of hours spent annually on direct inspections at U.S. nuclear power plants by 38 percent.
In addition to the proposed ROP changes, NRC staff published recommendations for the baseline security program that would reduce the number of direct inspection hours necessary for this program by about 50 percent compared to current levels. This includes the Force-on-Force (FOF) inspection program.
