I CONTAINEllT SYSTEMS CONTAte W T VENT SYSTEM LIMITINS CON 0! TION FOR OPERATION 3.6.1.8 The containment vent isolation valves MOV 6900 and MOV 6got shall be maintained closed by tagging the motor power supply breakers opes and main-taining the keyed hand switches locked in the closed position.

APPLICA81LITY:

MODES 1. 2, 3 and 4

~

ACTION:

With one or both containment vent isolation valves open, close the open valve (s) within one hour or be in at least HOT STAN08Y within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

SURVEILLANCE REQu!REMENTS 4.6.1.8 The containment vent isolation valves shall be determined closed at least once per 31 days by verifying that power to the motor operators is removed and the valves indicate shut.

REFUELING OPERATIONS l

BASES 3/4.9.10 and 3/4.9.11 WATER LEVEL-REACTOR VESSEL AND SPENT FUEL POOL WArtM LEVEL The restrictions on minimum water level ensure that sufficient water depth is available to remove 99% of the assumed 10% iodine gap activity released from the rupture of an irradiated fuel assembly.

The minimum water depth is consistent with the assumptions of the accident ar.alysis.

3/4.9.12 SPENT FUEL P00L VENTILATION $YSTEM The limitations on the spent fuel pool ventilation system ensure that all radioactive material released from an irradiated fuel assembly will be filtered through the HEPA filters and charcoal adsorber prior to discharge to the atmosphere.

The OPERA 8ILITY of this system and the resulting iodine removal capacity are consistent with the assumptions of the accident analyses.

3/4.9.13 SPENT FUEL CASK HANDLING CRANE The restriction on. movement of the spent fuel shipping cask within one cask length of any fuel assembly ensures that in the event this load is dropped (1) the stored spent fuel l assemblies will not be damaged, and (2) any possible distortion of fuel in the storage racks will not result is a critical array, 2le 4A coNTmMMENf VENT 1soLA7/oM #t.VES The operabilHy an d c.losure. re.sirietions on the conia& ment vent isolaHon' valves are sa Nicient to res +ric t raa%acr%e malerdrf relense fan a l'ae i element rup ture based upon the lack sf containesent pressuriretten po ten tial aMe in the. &EfuGUNG mod 2, b reno %en/ Mo.
