_ LIMITING CONDITION FOR OPERATION 3.10.6 The service water pumps required to be OPERABLE per Specifi-cation 3.7.1.2b3 do not have to be operating to permit isolating and draining the service water nuclear header for

, maintenance provided that:

l l a. The service water conventional header is lined up to supply cooling water to the required ECCS loads.

b. The draining / maintenance on the service water nuclear l header will not affect the service water conventional system or lineup described in a. above.

c. Two dedicated qualified personnel are assigned to initiate the service water conventional header should any of the following occur:

1. Any event occurs which requires ECCS actuation.

2. Primary coolant temperature exceeds 180*F.

3. A loss of off-site power occurs. .

APPLICABILITY: CONDITIONS 4 and 5 with the nuclear header inoperable.

ACTION: With the requirements of the above specification not satis-

, fied, restore the service water pumps to operable status per l the requirements of Specification 3.7.1.2.

SURVEILLANCE REQUIREMENTS 4.10.6.1 Prior to securing all service water pumps, verify that the

service water conventional header is lined up to supply cooling water for ECCS by verifying that each valve servicing safety related equipment that is not locked is j administratively controlled in its proper position.

4.10.6.2 Every four hours, verify that the primary coo'lant tempera- t ture is less than or equal to 180*F.

4.10.6.3 Prior to securing the service water pumps and once per eight hours, verify two-way communications exist between the Control Room and the Service Water Building.
