ACTION:

a.

With one or more of the above required Deluge Spray and/or Sprinkler Systems nonfunctional, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> establish a continuous fire watch for those areas in which both trains of redundant fire safe shutdown systems or components could be damaged(2l; for other areas, establish an hourly fire watch patro1(1 l_

Notes:

1.

For Completion Times stated in TECHNICAL REQUIREMENT ACTIONs which require periodic performance on a "once per.. " basis, the specified Frequency is met, after the initial performance, if the requirement is performed within 1.25 times the interval specified in the Completion Time, as measured from the previous performance or as measured from the time a specified condition of the Frequency is met.

2.

Additionally, monitor area temperatures and smoke detectors.

(See Bases item 8.)

TECHNICAL SURVEILLANCE REQUIREMENTS 4.7.12.2 Each of the above required Deluge Spray and/or Sprinkler Systems shall be demonstrated FUNCTIONAL:

a.

At least once per 31 days by verifying each valve (manual, power-operated, or automatic) outside containment in the flow path is in its correct position.

b.

At least once per 12 months by cycling each testable valve in the flow path through at least one complete cycle of full travel.

c.

At least once per 24 months by verifying each valve (manual, power-operated, or automatic) inside containment in the flow path is in its correct position.
