Request for Additional Information Tritium Production Program Interface Issue 7 Watts Bar Nuclear Plant, Unit 1 Docket No. 50-390 Interface Issue 7 Light-Load Handling System

1. In Part B.III.6.A.2 of Tennessee Valley Authoritys (TVAs) August 20, 2001, submittal, TVA states that damage to more than 24 tritium-producing burnable absorber rods contained in a consolidation canister is precluded for all credible impact scenarios.

What is the basis for this?

2. TVA states that an analysis was not performed for a fuel assembly falling onto a loaded consolidation canister, therefore administrative and/or design features will be in place to preclude damage. What are the specific administrative and /or design features, and when will these be implemented?
