Dear Mr. Abel:
In the Commonwealth Edison Company letter dated February 22, 1980, the commitment was made. to " conduct a low pressure gross leak test of containment prior to any startup from cold shutdown conditions.'" In our Ccafirmatory Order dated February 29, 1980 we reiterated this commitment and included your proposed test program as submitted by your February 22, 1980 letter.
In your letter dated August 15, 1980, you requested our concurrence with your understanding that you should " perform the actions indicated prior to any startup from cold shutdown conditions following only those outages which involved maintenance." There have been several discussions on this matter between our staffs and it is our intent here to formally documen+
our intent of the leak test.
Since plant activities during any cold shutdown can involve actions which might alter containment integrity including maintenance activities, the The nature low pressure leak test was required after each cold shutdown.
of some m&intenance activities may require more than a gross leak test especially if the maintenance is being done on a system necessary for containment integrity. The current regulations,10 CFR 50, Appendix J, would cover that type of maintenance activity rather than the gross leak test.
To reiterate our reouirements of the Confirmatory Order, the low pressure gross leak test of containment is to be performed prior to any startup Consistent with your February 22, 1980 letter from any cold shutdown.
l and our Confirmatory Order, if it can be determined that a gross leak test l
different from the one contained in the Confirmatory Order would provide the needed confic'ence in containment integrity and minimize the exposure to personnel, we would be receptive to such a proposal.
If you have any questions on this matter, please let us know.
Sincerely, l
