Why Shut Down / Decommission? End of life 40 years or 60 years with license extension Economics Politics A plant event!

NRC Requirements 10CFR20 Subpart E – Radiological criteria for license termination 10CFR50.75 – Reporting and record keeping for decommissioning planning 10CFR50.82 – Termination of license 10CFR51.53 – Postconstruction environmental reports 10CFR 51.95 – Requirements to consider final EIS

NRC Requirements Permanently cease operations Certify within 30 days 60-year clock Post-shutdown Decommissioning Activities Report (PSDAR) Within 2 years of ceasing operations Describes activities and schedule

NRC Requirements Decommissioning Cost Estimate (DCE) Within 2 years of PSDAR Allows full use of Nuclear Decommissioning Trust (NDT) funds License Termination Plan (LTP) 2 years in advance of license termination date Specifies final radiation survey and end use

Decommissioning Funding Nuclear Decommissioning Trust (NDT) funds Collected from ratepayers during operation Invested NRC oversight Funds through License Termination

Decommissioning Funding $ in millions $ in billions $2500 $2000 $1500 $1000 $500 $0 $90 $80 $70 $60 $50 $40 $30 $20 $10 $0

Decommissioning Approach Described in PSDAR DECON SAFSTOR ENTOMB What about the fuel? Independent Spent Fuel Storage Installation (ISFSI) ISFSI Only

Decommissioning Approach How to decide? Funding Multi-unit site Community and stakeholders Endpoint License terminated 25 mrem/year Or is it?

The Decommissioning Difference Nuclear, but no longer nuclear power plant Upon shutdown, no longer a power plant Not even “nuclear” once the fuel is out Project, but not a construction project It is radioactive It is waste It is as-built, as-is

The Decommissioning Difference

The Decommissioning Difference

Decommissioning Mindset Safety – it is different Project, not operations Waste, not a nuclear power plant A characterization problem, not a design problem Look to reduce requirements Keep the end state in mind
