DECOMMISSIONING PROGRAM

• Comprehensive regulations include:

• radiological cleanup criteria

• public involvement opportunities

• financial assurance requirements

• Effective decommissioning guidance

• Appropriate levels of oversight throughout decommissioning

• Extensive NRC experience in decommissioning radiological sites 5

PALISADES DECOMMISSIONING STATUS

• Palisades shut down on May 20, 2022, and submitted the certifications of permanent cessation of operations and permanent removal of fuel from the reactor vessel on June 13, 2022

• Review of the PSDAR and several other decommissioning transition licensing actions is underway

• The PSDAR will be used to inform the NRC licensing and oversight activities for Palisades 6

PSDAR REQUIREMENTS The PSDAR must contain:

• Description of planned activities

• High-level schedule considerations

• Site-specific cost estimate for decommissioning

• Projected costs of managing irradiated fuel

• Discussion of potential environmental impacts of decommissioning 7

PALISADES PSDAR CONTENT AND COST ESTIMATE HDI is preparing the plant for decommissioning and transfer of spent fuel to dry storage by 2025 Safe storage (a period of low activity) from 2026 to 2035 Complete radiological decommissioning by 2041 The 2022 decommissioning trust fund balance at license transfer to HDI was $552 million, and estimated cost to complete radiological decommissioning and terminate the Palisades license is $443 million (in 2020 dollars)

The PSDAR states that no decommissioning activities will be performed that result in significant environmental impacts not previously reviewed for the site 8

DECOMMISSIONING EXPERIENCE

• The NRCs current decommissioning regulations are performance-based and risk-informed

• Extensive decommissioning experience

• A total of eleven power reactor sites have completed decommissioning and had the reactor licenses terminated for unrestricted use outside of the dry fuel storage facility 18 0

PSDAR QUESTION AND UPDATE PROCESS

• The NRC staff is reviewing the Palisades 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 21

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 22

REACTOR DECOMMISSIONING INSPECTIONS End Program Coordinate confirmatory survey activities to ensure site cleanup criteria (dose of less than 25 millirem 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 23 23

NRC INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI)

INSPECTION PROGRAM 24

• Inspections at the manufacturing facility where the ISFSI components are fabricated

• Inspectors onsite during the construction of the concrete pad that will house the storage casks

• Knowledgeable NRC staff assess the readiness of the licensee to use the system before operation

SPENT FUEL STORAGE FACILITY INSPECTIONS IMC 2690 - Inspection Program for Dry Storage of Spent Reactor Fuel at Independent Spent Fuel Storage Installations 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 25 25

HOW DOES EMERGENCY PLANNING CHANGE?

• Emergency preparedness remains

• All hazards approach utilized instead of formal pre-planned offsite radiological response plans

• Based on changes in risks and consequences as the power reactor undergoes decommissioning 26

HOW DOES FACILITY SECURITY CHANGE?

• Security controls remain in place

• Some key features include:

• intrusion detection and response

• assessment of alarms

• off-site assistance, when necessary

• A security plan is also required for the ISFSI 27
