NOTES (Continued)- l

21. Automatic isolation signal causes TIP to retract; ball valve closes when probe is fully retracted. ,
22. Isolation barrier remains water filled or a water seal remains in the

. line post-LOCA. Isolation valve may be tested with water. Isolation valve leakage is not included in 0.60 La total Type B & C tests.

23. Valve does not receive an'isolati,on signal. Valves will be open during Type A test. Type C test not required.
24. Both isolation signals required for valve closure.

2,5. Deleted -

26. Valve stroke times listed are maximum times verified by testing per Speci-fication 4.0.5 acceptance criteria. The closure times for isolation valves in lines in which high-energy line breaks could occur are identified with a single asterisk. The closure times for isolation valves in lines which provide an open path from the containment to the environs are ioentified with a double asterisk.
27. The reactor vessel head seal leak tietection line (penetration 29A) excess flow check valve is not subject to OPERABILITY testing. This valve will not be exposed to primary system pressure except under the unlikely con-ditions of a seal failure where it could be partially pressurized to reactor pressure. Any leakage path is restricted at the source; therefore, this valve need not be OPERABILITY tested.

'd s 28. (DELETED)

29. Valve may be open during normal operation; capable of manual isolation from. control room. Position will be controlled procedurally.
30. Valve normally open, closes on scram signal.
31. Valve 41-1016 is an outboard isolation barrier for penetrations X-9A, B and X-44 Leakage through valve 41-1016 is included in the total for penetration X-44 only.
32. Feedwater long path recirculation valves are sealed closed whenever the reactor is critical and reactor pressure is greater than 600 psig. The valves are expected to be opened only in the following instances:

a Flushing of 'the condensate and feedwater systems during plant startup.

b. Reactor pressure vessel hydrostatic testing, which is conducted follow-ing each refueling outage prior to commencing plant startup.

Therefore, valve stroke timing in accordance with Specification 4.0.5 is not required.

33. Valve also constitutes a Unit 2 Reactor Enclosure Secondary Containment Automatic Isolation Valve and a Refueling Area Secondary Containment Automatic Isolation Valve as shown in Table 3.6.5.2.1-1 and Table 3.6.5.2.2-1 respectively.
