This exceeded the 60 +/
15 minute hourly fire watch requirement established in response to NRC Bulletir. 92-01, Supplement 1.
Further investigation revealed that the individual assigned to completing the required fire watch did eot enter Room 325 during the two patrols he performed from 1800 until 2000 on September 8, 1992.
A However, a qualified fire vatch individv3'. enters 3 Room 325 at 1822 and again at 1921 therefore, technically only one lite watnh was missed.
This event was not detected during the hourly reviews of fire watch logs because the fire watch log was incorrectl'/ signed by the individual as if the vatch was properly performed at 1806 and 1906.
Potential Condition Adverse To Quali.ty Report 92-0367 was initiated on September 10, 1992 to address this incident.
