P,
= appropriately measured test pressures (psig)
- c. The ILRT's shall be performed at the following minimum frequency:
1.
Prior to initial unit operation.
- 2. - After the preoperational leakage rate tests, a set of three Type A tests shall be performed at approximately equal intervals during each 10 year service period.*
These intervals may be extended up to eight months if necessary to coincide with re-fueling outage,
- d. The allowable leakage rates, L,and L",
shall be less than 0.75 L, and 0.75 L, for the reduced pressure tests and peak pressure tests, respectively.
- Except for third Type A test in the second 10 year service period, which will be performed during the PBAPS, Unit 2 refueling outage 11 currently scheduled for September 1996.
