NRC Approves Changes to ROP

The Commission has issued a Staff Requirements Memorandum (SRM) approving the recommendation made by NRC Staff in SECY-15-0108 to revise the definition of degraded cornerstone as used in the Reactor Oversight Process (ROP) Action Matrix. The ROP Action Matrix assesses a licensee’s performance across seven aspects of facility operation, called cornerstones. Currently, when two white-level inputs are in the same cornerstone, it is considered a degraded cornerstone in the ROP. With this SRM, the Commission approved a change requiring three white-level inputs. After performing a risked informed evaluation, the Staff concluded, and the Commission agreed, that three white inputs in the same cornerstone were more indicative of a degraded cornerstone than only two white inputs. The Commission also directed the Staff to revise Inspection Procedure 95001, “Supplemental Inspection for One or Two White Inputs in a Strategic Performance Area,” to include additional resources and guidance to be used to review licensee common cause analyses when a licensee has a second white input in the same cornerstone. These changes will take effect in January 2016 and do not alter the current oversight status of any plants.
