Waterford 3 SES Docket No. 50-382 Control of Ileavy Loads V

4 N*>O

Dear Mr. Tedesco:

In NRC questions 10.14 and 10.33, the NRC took a position requiring LP&L to perform an analysis of the effects of dropping any load handled by the containment polar crane. The analysis was to demonstrate that no adverse radiological consequences due to damage of reactor coolant system components or fuel would result from such a load drop. In responding to question 10.33, LP&L agreed to perform a heavy loads analysis in accordance with NUREG-0612,

" Control of Heavy Loads at Nuclear Power Plants".

In response to the earlier NRC question, 10.14, LP&L committed to a 125%

~

dummy load static test of the polar crane to oe performed at the start of every refueling in order to provide justification for waiving the load drop analysis. As this response was considered unacceptable and, in light of LP&L's cubsequent commitment to a heavy loads analysis, LP&L proposes the following:

1. The 125% dummy load static test of the polar crane prior to each refueling will no longer be required, having been replaced by the load drop analysis.

I 2. Should the load drop analysis review not be complete or be deemed unacceptable prior to startup, a 125% pre-operational static load test of the polar crane w'.11 be performed.

3. Should the load drop analysis review not be completed by the first refueling, the polar crane will be tested at 100% rated load.

The FSAR will be changed to reflect this revision in the next FSAR amendment.

Preliminary discussions with members of your staff indicate that this approach should be acceptable.
