1 Decommissioning Funding Requirements and Oversight June 7, 2022 Decommissioning Strategy Forum Richard Turtil, Senior Financial Analyst Office of Nuclear Material Safety and Safeguards

Decommissioning Funding Overview

• Reactor Licensee Requirements

• Minimum Funding Requirements and Formula Calculation - initial and throughout operations

• Methods of Financial Assurance

• Transition to Site-Specific Cost Estimate

• Decommissioning Funding Lifecycle

• Current NRC Rulemaking 2

10 CFR 50.75 - Reporting and Recordkeeping for Decommissioning Planning

• Purpose Provides reasonable assurance that funds will be available for decommissioning after a reactor ceases operations.

• Initial Funding Provided by licensee prior to authorization for initial fuel load and operation.

• Licensee Accumulates Funds over Life of Operating Reactor Reported to the NRC at least every two years.

Reported annually if within 5 years of cessation of operations and while in decommissioning.

Minimum Decommissioning Funding Requirement NRC Minimum Funding Amount (MFA) adjusted for changes in Labor, Energy, and LLW Burial costs over life of reactor.

MFA varies by reactor based on:

- Size of Reactor (MWt) - Type of Reactor (BWR vs. PWR)

MFA is not a site-specific cost estimate.

MFA covers Radiological Decommissioning only.

Does not consider spent fuel management, site restoration, and other non-radiological costs.

4

NRC Minimum Formula Amount =

(Regulatory Formula Amount) x (Adjustment Factor)

Example Calculations (approximate estimates):

PWR and BWR of 3,400 MWt Capacity or Greater (Data as of December 31, 2020)

PWR

($105 million) x (labor, energy, and LLW burial adjustment factor of ~ 4.00 - 5.00)

= ~$420 - $525 million $US 2020 BWR

($135 million) x (labor, energy, and LLW burial adjustment factor of ~ 5.00)

= ~$685 million $US 2020

Funding Methods

• Prepayment

• External sinking fund

• Surety method, insurance, or other guarantee

• Statement of intent

• Contractual obligations

• Other mechanism or combination 6

Transition to Site-Specific Cost Estimate

• At or about 5 years of the projected end-of-life, a site-specific cost estimate (SSCE) is required which includes a complete up-to-date assessment of major factors that could affect anticipated radiological decommissioning costs.

• The SSCE must be greater than or equal to the NRC Minimum Formula Amount.

7

Decommissioning Fund Lifecycle

• Initial Certification of Financial Assurance.

• Maintain the NRC MFA throughout operating life of reactor; replaced by SSCE near end of operations and into decommissioning.

• Monitoring and Updating of Decommissioning Funding -

Licensee provides Decommissioning Fund Status Report to the NRC (every 2 years); annually in decommissioning.

Licensee Provides SSCE 5 years prior to permanent cessation of operations & in Post-Shutdown Decommissioning Activities Report.

NRC Inspectors coordinate decommissioning oversight with the technical decommissioning and financial assessment staff.

8

Transition to Decommissioning Rulemaking -

Decommissioning Funding Assurance Current GUIDANCE -

o Non-rate-regulated licensees should make up shortfalls in decommissioning funding within 2 years and electric utility licensees within 5 years.

Proposed RULE would -

o Clarify that when a licensee identifies a shortfall in biennial report, must obtain additional financial assurance to cover the shortfall in the next report.

o Modify biennial reporting frequency for operating reactors to 3-year frequency.

The 3/3/2022 notice announcing the proposed RULE seeks public comment on four decommissioning funding issues -

o Financial Assurance and the Minimum Formula Approach/Bulk o Site-Specific Cost Analysis o Decommissioning Trust Fund Assets for Spent Fuel Management and Other Uses o Timing of Decommissioning Fund Assurance Reporting 9
