• when the conditions of Section 3.5.b.1.a. b, c, and d are met, and reactor water level is closely monitored and logged hourly. The Sta'dbyn Gas Treatment System wil: be mar.ually initiated if reactor water level drops to the .;

low level trip set point.

hh. The high flow trip function for "B" Isolation Condenser is bypassed upon initiation o the alternate shutdown panel. This prevents a spurious trip of the isolation condenser in the event of fire induced circuit damage.

11. Instrument shall be operable during main condenser air ejector operation except that a channel may be taken out-of-service for the purpose of a check, calibration, test, or maintenance without declaring it to be inoperable.

aj. With no channel OPERABLE, main condenser offgas may be released to the environment for as 1. ,9 as 72 hoces provided the stack radioactive noble gis monitor is OPERABLE. Otherwise, te in at least SHilTDOWN CONDITICN within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
