Operating Experience Smart Sample (OpESS) Program
The OpESS program is designed to provide NRC inspection staff a detailed synopsis of selected operating experience which the agency considers to have generic safety implication. The OpESS is designed as an additional tool to be used by agency staff in ROP baseline inspection preparation. The information and trends identified from OpESS inspections may provide further indication that a specific issue warrants additional agency action.
Operating Experience Smart Samples
Each OpESS has a unique and sequential identifier. The designator FY is "Fiscal Year," which will support tracking by the NRR Operating Experience Branch for determining OpESS utilization and effectiveness.
