Docket Hos.:
50-387 and 50-388 JULY 8 igst Hr. Norman W. Curtis Vice President - Engineering and Construction Pennsylvania Power a Light Co.
Two North Ninth Street Allentown, PA 13101
Dear Mr.,
Curtis:
SUBJECT:
PPSL, APPEAL OF THE NRC STAFF POSITION REGARDING LOW PRESSURE CONTAINMENT LEAKAGE TEST FREQUENCY Pennsylvania; Power lid Light Company has propose)that the test frequency for the low pressure steam bypass test he the same as that required for the Integrated Leak Rate Tests (ILRT), i.e., about every 3 I/3 years.
The first test would be performed during the initial ILRT and then during every sub-sequent ILRT.
The NRC position as reflected in SRP 6.2.1.1c is that periodic leak testing be performed at each refueling, an approximate 18-month period.
The applicant has requested the 3-year interval based on the added integrity to be gained from specific design features; including, continuous liner plates, seamless downcomer pipe,. flued SRV heads at the point of diaphragm slab pene-
- trations, and seal welded plates at penetrations of the diaphragm slab..
The NRC has. considered these design items and the high degree of potential protection to be gained from their presence.
However,, the newness of the Hark II design and the importance of protecting against the relatively low capability for accommodating steam bypass. inherent in this design requires that an early record of bypass integrity be proven through periodic testing at. about the refueling interval.
