Technical Specification 3.3.3.7 requires that the fire detection instru-mentation for each fire detection zone be operable.
If the. equipment is inoperable, it then requires that a fire patrol inspect the zone at least once per hour.
If the instrument is located inside containment, the containment must be inspected at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> or the containment temperatures be monitored at least once per hour.
Contrary to the above, the licensee failed to monitor containment tempera-tures each hour between the hours of 7:00 P.M. on July 29, 1987, and-2:00 a.m. on July 30, 1987, and failed to establish a fire watch patrol in fire zones ZZZ, WWW, LLL and Q between the hours of 2:00 a.m. and 12:30 p.m. on July 30, 1987, while the fire detection instrumentation for these areas were inoperable.

established, implemented and maintained.
System Operating Procedure l
SOP-304, implements this requirement for 7.2 kV switchgear and states to operate transformers XTF-4-ES and XTF-5-ES in parallel.
Contrary to the above, on September 3,1987, the licensee failed to operate the transformers in parallel or evaluate the change in operation from that described in the safety analysis report.
