Dear Mr. Mangan:
SUBJECT:
SAFETY EVALUATION -
MASONRY WALL DESIGN, IE BULLETIN 80-11 (TAC 42884)
Re:
Nine Mile Point Nuclear Station, Unit No.
1 We have completed our review of your response to IE Bulletin 80-11, Masonry Wall Design, for Nine Mile Point Unit 1, as submitted in letters dated July 8,
- 1980, November 10,
- 1980, June 14,
- 1982, June 24,
- 1983, and June 21, 1984.
Your use of the "leak-before-break" concept to eliminate consideration of the pressure loads resulting from a high energy line break is under review as a rule-making issue.
However, the generic structural engineering review of the Masonry Wall Design for Nine Mile Point 1 is complete.
The enclosed Safety Evaluation supporting our findings is enclosed.
