MSIV LCS B 3.6.1.9 BASES ACTIONS C.1 and C.2 (continued)
If the MSIV LCS subsystem cannot be restored to OPERABLE status within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full' l
power conditions in an orderly manner and without challenging plant systems.
SURVEILLANCE SR 3.6.1.9.1 REQUIREMENTS Each outboard MSIV LCS blower is operated for 215 minutes l
1 to verify OPERABILITY. The 31 day Frequency was developed i
considering the known reliability of the LCS blower and controls, the two subsystem redundancy, and the low probability of a significant degradation of the MSIV LCS subsystem occurring between surveillances and has been shown to be acceptable through operating experience.
l i
SR 3.6.1.9.2 Deleted l
SR 3.6.1.9.3 A system functional test is performed to ensure that the t
MSIV LCS will operate through its operating sequence.
This includes verifying that the automatic positioning of the valves and the operation of each interlock and timer are correct, that the blowers start and develop the required flow rate and the necessary vacuum, and the upstream heaters meet current or wattage draw requirements (if not used to verify electrical continuity in SR 3.6.1.9.2).
