()

d. Type B and C tests shall be conducteg with gas at P , 34.7 psig," at intervals no greater than 24 months except for test$ involving:

1. Air locks,

2. Hain steam line isolation valves,

3. Valves pressurized with fluid from a seal system, s

4, ECCS and RCIC containment isolation valves in hydrostatically tested lines which penetrate the primary containment, and

5. Purge supply and exhaust isolation valves with resilient seal s.

e. Air locks shall be tested and demonstrated OPERABLE per Surveillance Requirement 4.6.1.3.

Hain steam line isolation valves shall be leak tested at least once per 18 'months.

g. Leakage from isolation salves that are sealed with fluid from a seal system may be excluded, subject to the provisions of Appendix J,Section III.C.3, when determ>ning the combined leakage rate provided the seal system and valves're~pressurized to at least 1.10 P ,
