OBJECTIVES OF THE DECOMMISSIONING INSPECTION PROGRAM
- Oversight and monitoring conducted over the entire period of the decommissioning process
- Objectively verify the safe conduct of decommissioning activities, including dismantlement and decontamination
- Verify adequacy of licensee procedures and controls
- Ensure safety problems and violations are promptly identified and corrected, and effective actions are taken to prevent recurrence
- Examine and address trends in safety performance 9
REACTOR DECOMMISSIONING INSPECTIONS End Program Coordinate confirmatory survey activities to ensure site cleanup criteria (dose of less than 25 millrem per year from all pathways)
License termination (outside dry fuel storage area)
Decommissioning Inspections Inspection Manual Chapter 2561 Flexible scope and frequency Inspection reports publicly available in ADAMS Enter Program Fuel removed from core; placed in pool Transition from Operating Reactor Oversight Process 10 10
SPENT FUEL STORAGE FACILITY INSPECTIONS IMC 2690 - Inspection Program for Dry Storage of Spent Reactor Fuel at Independent Spent Fuel Storage Installations (ISFSI)
NRC inspections performed during:
- onsite fabrication and construction of the ISFSI
- preoperational testing (i.e., dry runs)
- initial fuel loading campaign
- routine ISFSI inspections
- any significant evolutions involving the ISFSI 11 11
PSDAR REQUIREMENTS The PSDAR should contain:
- Description of planned decommissioning activities
- High-level schedule considerations
- Site-specific cost estimate for decommissioning
- Discussion of potential environmental impacts of decommissioning
- May contain the irradiated fuel management plan as part of the PSDAR 12
CONTENTS OF THE DIABLO CANYON PSDAR BRANDY LOPEZ, PACIFIC GAS & ELECTRIC 13
PSDAR REVIEW PROCESS PUBLIC OUTREACH The NRC notices receipt of the PSDAR in the Federal Register and requests public comments The NRC also schedules a public meeting in the vicinity of the plant to discuss the PSDAR and solicit public comments TECHNICAL REVIEW Technical review of the decommissioning strategy and schedule Financial review of the decommissioning and spent fuel management funding Environmental review for decommissioning the site 14
PSDAR QUESTION AND UPDATE PROCESS The NRC staff is reviewing the DCNPP PSDAR and will request any additional information needed to conclude that the PSDAR contains the required information The PSDAR may be updated as part of the initial review process and will become part of the staffs PSDAR acceptance letter Subsequent updates to the PSDAR will be publicly available and provided to the State, but do not require additional acceptance 15
