LIMITING CONDITIONS FOR OPERATION SURVEILIANCE REQUIREMENTS 3.9.B 4.9.A.
(cont'd) i B.
Operation with Inocerable Eauinment Whenever the reactor is in Run Mode or Startup Mode with the reactor not in a Cold Condition, the availabil-ity of electric power shall be as specified in 3.9.A.1, except as specified in 3.9.B.1.
1.
Incomina Power a.
From and after the date incoming power is not available from a I
startup or emergency transformer, continued reactor operation is permissible under this condition for seven' days.
At the end of this period, provided the second source of incoming power has not been made immediately available, the NRC must be notified of the event and the plan to restore this second source, i
During this period,. the two diesel '
generators and associated critical buses must be demonstrated to be operable.
j b.
From and after the date that incoming power is not available from both start-up and emergency trans-i formers (i.e.,
both failed), con-tinued operation is permissible, provided the two diesel generators and associated critical buses are demonstrated to be operable, all core and containment cooling systems are operable, reactor power level is reduced to 25% of the rated and NRC is notified within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the situation, the precautions to be taken during this period and the plans for prompt restoration of
