OCT 31 1979 Docket No. 50-341 Dr. Wayne H. Jens Assistant Vice President Engineering and Construction Detroit Edison Company 2000 Second Avenue Detroit, Michigan 48226
Dear Dr. Jens:
SUBJECT:
ACCEPTANCE CRITERIA FOR THE MARK I CONTAINMENT LONG TERM PROGRAM (Enrico-Fermi Atomic Power Plant, Unit 2)
The staff has completed its review of the generic aspects of the Mark I Containment Long Term Program (LTP).
The results of this review are reflected in the enclosed acceptance criteria, which are intended to be used to perform individual plant-unique analyses for each Mark I facility.
These criteria have been developed from the staff's evaluation of the Mark I LTP Load Definition Report, Plant Unique Analysis Applications Guide, and related suppression pool hydrodynamic experimental and analytical programs, which have been submitted by the Mark I Cwners Group.
In developing these criteria, we have considered verbal comments provided by representatives of the Mark I Owners Group on a draft of the criteria issued August 2, 1979. These comments were presented to the staff during a meeting held on August 15, 1979, and supplemen,ted by additional information provided in a letter from General Electric dated September 7,1979.
This information and internal comments by the staff and our consultants have resulted in some modifications to the draft criteria.
However, others of the Owners Group recommendations were not adopted for the NRC criteria, based on the staff's judgment relative to the interpretation of specific data or analyses.
In certain cases, the staff's generic criteria identify specific hydrodynamic load assessment techniques that will have to be evaluated on a plant-specific basis. However, deviations from any other generic criteria should be avoided.
The criteria also identify additional experimental verificaticn that must be obtained for " condensation oscillation" load uncertainty.
This requirement was communicated to you earlier in our letter dated October 1,1979.

.W Dr. Wayne H. Jens OCT 3 I 979 Within 30 days of your receipt of this letter, we request that you provide the schedule for submittal of the LTP plant-unique analysis for your facility.
The staff presently expects to issue the generic Safety Evaluatign Report supporting these criteria in December 1979.
Should you have any' questions regarding this action contact C. Grimes (301-492-8204).
Sincerely,
'i G'iYC Ltct s 4 /b'k Stevel A. Varga, Acting Assys want
