Meteorological nonitoring instrumentation channels inoperable contrary to Technical Specification 3.3.3.4.
Conditions Prior to Occurrence:
Mode 5 operation, Plant E!c a t u p .
Description of Occurrence:
At 1940, during plant heatup, it was discovered that the temperature device at the 175' level of the meteorological monitoring tower was producing erratic indication. Instrumen-tation troubleshoot ing revealed no apparent cause and no cor-rective maintenance was required. Functional testing was performed through meteorological System Surveillance SP-137 from 17 March to 22 March with satisfactory results. The temperature device was returned to service at 0800 on 22 March 1979.
Designation of Apparent Cause:
tae cause of this event cannot be determined.
Analysis of Occurrence:
There was no hazard to the plant or general 511c as no gaseous releases were in progress.
Corrective Action Meteorological System Surveillance SP-157 was performed satis-factorily and the device returned to service at 0800 on 22 March 1979. No further corrective action required.
Failure Data:
Third occurrence reported for this device. Reference LER's 78-26 and 78-56.
