Spent Fuel Storage - Background
"* SQN Spent Fuel Pool
- Common to both units
- Transfer canal and cask loading area adjacent
- Uses boral as neutron poison
- Boron concentration maintained between 2,000 and 2,700 ppm
- Pool temperature typically between 70 OF and 112 OF
"* Spent Fuel Pool Capacity
- 2,091 storage locations installed with 2,089 useable storage locations
- 8 non-fuel items stored (debris container, boral specimen array, etc.)
- 1,700 spent fuel assemblies stored in pool
- 381 open cells, but full utilization limited by TS requirements Smith 2
Spent Fuel Storage - Background
- SQN Spent Fuel Storage Considerations Originally estimated loss of full core off-load capacity 2002 by Spring
- Credit for SFP boron concentration extends SFP full core capacity loss to Fall 2004 - (U1C13)
- Comprehensive study of spent fuel storage options m Onsite dry cask storage determined to be best option
- Proposals, Evaluations, and Decisions SQN issues request for proposals from selected vendors TVA Board awards contract to Holtec International - April 2000 SQN enters contract with Holtec International - June 2000 3

NRC Review Considerations
- TVA will be revising the Radiological Emergency Plan Submit to NRC reviewing the Security Plan and submitting to NRC, as appropriate
- TVA appreciates NRC efforts towards a timely and approval of Amendment 1 to HI-STORM 1 Certificate of Compliance 1014 NRC approval of LAR 2 to HI-STORM 100 COc review 00 C 1014 Critical element for SQN is update to the MPCs thermal rating
- Holtec submitted for NRC review on March 4, 2002 TVA requests NRC approval by Spring 2003 25 Smith
