LER #: 50-366/1982-063-Licensee: Georgia Power Company Facility Name: Edwin I. Hatch Docket #: 50-366 Narrative Report for LER 50-366/1982-063 On June 14, 1982, with Unit Two-increasing power from approximately 97 MWT, and while performing routine surveillance, per procedure "Consip Delphi Model K-IV Hydrogen and Oxygen Analyzer FT and C",
the "B" containment Hydrogen and Oxygen Analyzer was discovered to be out of calibration. (Analysis for both Hydrogen and Oxygen as indicated was low.) Technical Specificiations Table 3.3.6.4-1 i requires two operable channels. This requirement was not met during f the period the instrument was out of calibration. The last recorded a calibration occurred after maintenance to replace the internal sampling. flow components which was completed June 4, 1982. The redundant "A" Analyzer was operable. This event-has no effect on l the Unit One H2 O2 Analyzer which is supplied by a different manufacturer. Plant operation was not affected. The health and i safety of the public was not affected. This event was not repetitive.
- The cause of this event has been attributed to instrument drift.
The instrument was recalibrated, as part of the functional test and 4
calibration procedure being performed at the time of the discovery, and returned to service.
