Gentlemen:
Re:
Nine Mile Point Unit 1 Docket No. 50-220 DPR-63 Your letter of March 20, 1978 requested an evaluation of the effect on the Nine Mile Point Unit 1 containment of multiple subsequent actuations of safety/relief valves following a postulated isolation event.
Your letter also transmitted criteria for this evaluation.
This evaluation is part of the Mark I Containment Long Term, Program; therefoxe a common approach will be taken.
Due to the generic issues
- involved, we are unable to submit a response in the time frame requested.
- However, an evaluation for Nine Mile Point Unit 1 will be submitted on or before July 31, 1978.
Very truly yours,
