LIMITING CONDITION FOR OPERATION 3.7.1.1 The shutdown service water (SX) loop (s) shall be OPERABLE during times when its associated system (s) or components are required to be OPERABLE. Each OPERABLE SX loop shall be comprised of:

a. One OPERABLE SX pump, and

b. An OPERABLE flow path capable of taking suction from ultimate heat sink and transferring water through the associated system (s) and components that are required to be OPERABLE.

APPLICABILITY: OPERATIONAL CONDITIONS 1, 2, 3, 4, 5, and *. .

ACTION:

Vith a shutdown service water loop (s) inoperable and with its associated sys-tem (s) or component (s) required to be OPERABLE, declare the associated system (s) or component (s) inoperable and take the ACTION required by Specification (s) 3.4.9.1, 3.[4245J.s3.5.263414J.8JJ.4Q1JgdJ41120s S ec ,Q c.acco 3
