  52. What do you need for 100% post accident containment cooling for LCO 3.6.6. Containment Cooling?
    • One hundred percent of the required post accident cooling capability can be provided with both MSIV bypass valves closed if either;
    •  1. Two containment spray pumps, and two spray headers are OPERABLE, or
    •  2. One containment spray pump, two spray headers, and three safety related CACs, are OPERABLE (at least two service water pumps must be OPERABLE if CACs are to be relied upon).

    • One hundred percent of the required post accident cooling capability can be provided for operation with a MSIV bypass valve open or closed if either;
    •  1. Two containment spray pumps, two spray headers, and two safety related CACs, are OPERABLE (at least two service water pumps must be OPERABLE if CACs are to be relied upon), or
    •  2. One containment spray pump, one spray header, and three safety related CACs are OPERABLE (at least three service water pumps must be OPERABLE to provide the necessary service water flow to assure OPERABILITY of the CACs).


    • One hundred percent of the post accident cooling can be provided with the Containment Spray side of SDC Heat Exchanger E-60B out of service if the following equipment is OPERABLE: three safety related Containment Air Coolers, two Containment Spray Pumps, two spray headers, CCW pumps P-52A and P-52B, two SWS pumps, and both CCW Heat Exchangers, and if
    •  1. One CCW Containment Isolation Valve, CV-0910, CV-0911, or CV-0940, is OPERABLE, and
    •  2. Two CCW isolation valves for the non-safety related loads outside the containment, CV-0944A and CV-0944 (or CV-0977B), are OPERABLE.
  53. What do you need per LCO 3.7.8 Service Water System for 100% post accident cooling?
    • One hundred percent of the required SWS post accident cooling capability can be provided by any one SWS pump if SWS flow both to the non-critical header and to the critical loads inside the containment are capable of being isolated.
    •  1. The capability to isolate SWS flow to the non-critical SWS header requires its isolation valve, CV-1359, to be OPERABLE.
    • 2. The allowance to isolate SWS flow to the containment requires the ability to provide post accident containment cooling without reliance on CACs. The capability to isolate SWS flow to the containment requires one SWS Containment Isolation Valve, CV-0824 or CV-0847, to be OPERABLE.

    One hundred percent of the required SWS post accident cooling capability can be provided by any two SWS pumps if SWS flow either to the non-critical header or to the critical loads inside the containment are capable of being isolated.

    One hundred percent of the required SWS post accident cooling capability can be provided by three SWS pumps even with SWS flow being provided to both the CACs and the Non-critical SWS header.
  54. What do you need per LCO 3.7.7 Component Cooling Water System for 100% post accident cooling?
    • One hundred percent of the post accident CCW cooling can be provided with the SWS side of one CCW heat exchanger out of service if the following equipment is OPERABLE:
    • 3 safety related Containment Air Coolers,
    • 2 Containment Spray Pumps,
    • CCW pumps P-52A and P-52B,
    • 2 SWS pumps,
    • and both Shutdown Cooling Heat Exchangers,
    • and if
    •  1. One CCW Containment header valve, CV-0910, CV-0911, or CV-0940, is OPERABLE, and
    •  2. Two CCW isolation valves for the non-safety related loads outside the containment, CV-0944A and CV-0944 (or CV-0977B), are OPERABLE.


    • One hundred percent of the required CCW post accident cooling capability can be provided by one CCW pump if both CCW heat exchangers are available and if:
    •  1. One CCW Containment header valve, CV-0910, CV-0911, or CV-0940, is OPERABLE, and
    •  2. Two CCW isolation valves for the non-safety related loads outside the containment, CV-0944A and CV-0944 (or CV-0977B), are OPERABLE.

    • One hundred percent of the required CCW post accident cooling capability can be provided by two CCW pumps if both CCW heat exchangers are available and if:
    •  1. One CCW Containment header valve, CV-0910, CV-0911, or CV-0940, is OPERABLE, or
