3.7.2 A.
Tha sp:cifications in 3.7.1 cay b2 modified to allow one of the following condiitons to exist after the reactor has been heated above 200F.
Except as indicated in the fol hwing conditions, if any of these conditions are not met; a hot shutdown shall be initiated within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
If the condition is not cleared within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, the reactor shall be brought to cold shutdown within an additional 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
B.
In the event that one of the offsite power sources specified in 3.7.1. A (1 or 2) is inoperable, reactor operation may continue for i
up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> if the availability of the diesel generators is immediately verified.
C.
Either one of the two diesel generators may be inoperable for up to 7 days in any month provided that during such 7 days the operability of the remaining diesel generator is demonstrated immediately and daily thereafter, there are no inoperable ESF components associated with the operable diesel generator, and provided that the two sources of off-site power specified in 3.7.1.A(1) or 3.7.1.A(2) are available.
D.
Any 4160V, 480V, or 120V switchgear, load center, motor control center, or distribution panel in one of the two ESF distribution systems may be inoperable for up to 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, provided that the operability of the diesel generator associated with the operable ESF distribution system is demonstrated immediately and all of the components of the operable distribution system are operable.
If the ESF distribution system is not returned to service at the end of the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> period, specification 3.7.2.A shall apply.
E.
Two station battery charges may be inoperable for 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, after which specification 3.7.2.A shall apply.
F.
One of the two station batteries and the associated distribution system may be inoperable for 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> provided that there are no inoperable safety related components associated with the remaining 1
station battery which are redundant to the inoperable station battery and the operability of the diesel generator is veritied immediately.
If the battery is not returned to service at the end of the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> period, specification 3.7.2.A shall apply.
G.
Two control power sources from the plant to the switchyard and the attendant distribution system may be inoperable for 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, after which specification 3.7.2.A shall apply.
H.
If the requirements of specification 3.7.1.G cannot be met, either:
(1) place all Startup Transformer No. 2 feeder breakers in
" pull-to-lock" within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, restore the inoperable interlocks to operable status within 30 days or submit a special report purstant to specification 6.12.3.2 outlining cause of the failure, proposed corrective action and schedule for implementation; or NOTE:
The provisions of specification 3.0.4 are not applicable.
(2) apply the action requirements of Table 3.5.1-1, Note 14.
