Irradiated Fuel Management Plan 12

Current Dry Fuel Storage Current ISFSI facility:

  • 50 loaded Spent Fuel canisters
  • 12 empty modules
  • Space for 26 more modules The existing ISFSI storage facility must be increased to accommodate approximately 100 additional canisters 13

Used Fuel Storage Current State Future State Future State Off-site Expanded Dry Fuel Storage Fuel Pad Assemblies in Spent Fuel Pools = 2668 Approximately100 canisters To DOE containing 2668 Fuel Assemblies 3855 Fuel (includes 1115 High Burn-up Assemblies in Fuel Assemblies) approximately 150 canisters Existing Dry Fuel Storage Pad (with Unit 1,2,3 used fuel) 50 canisters 1187 Fuel Assemblies 50 canisters (includes 8 High Burn-up Fuel already in place Assemblies) 14

Irradiated Fuel Management Plan

Basis

  • NRC review in accordance with its standard process
  • No standard format or specific guidance
  • Written notification discussing the Decommissioning Plan within 2 years following permanent cessation of operation of the reactor
  • Program by which the licensee intends to manage and provide funding for the management of all irradiated fuel until the fuel is transferred to the Structure Secretary of Energy for its ultimate disposal in a repository
  • San Onofres program is to move the fuel from wet storage in the spent fuel pools to the dry storage pad 15

San Onofre Irradiated Fuel Management Plan Overview

  • 2668 fuel assemblies in spent fuel pools to be safely transferred to the dry fuel storage pad by 2019
  • Assumed start date of 2024 for DOE
  • San Onofre fuel target removal date 2049
  • Adequacy of existing funds
  • Spent fuel pools cooled by stand-alone cooling and filtration units 16

Decommissioning Cost Estimate 17

Decommissioning Cost Estimate

Basis

  • EnergySolutions estimating model and data
  • SONGS-specific walk down validation for quantities
  • Discusses the Decommissioning Plan

  • CPUC regulates all spending from the Nuclear Decommissioning Trust, including review, approval and reasonableness
  • NRC regulates all radiological decommissioning
  • NRC regulates used fuel management 21

Open Communication Public engagement and education includes:

  • A Community Engagement Panel to foster open dialogue
  • Decommissioning Education Fairs
