NARRATIVE

REPORT

)

Georgia Power Company Plant E. I. Hatch Baxley, Georgia 31513 Reportable Occurrence Report No. 50-321/1980-030.

With the mode switch in run and the reactor at 2432 MWt, it was discovered that the "B" analyzer of the Primary Containment Hydrogen and Oxygen analyzer was inoperative. The "A" analyzer was functioning properly. The failure of the analyzer is repetitive as last reported on Reportable Occurrence Report 50-321/1979-097. However, this is the first failure that can be attributed to the pre-filter installation. There were no effects upon the public health or safety.

The cause of this occurrence is attributed to personnel error.

Upon investi-gation of the problem, moisture was found in the sensing lines.

The. sample pre-filter was found incorrectly installed and it is believed it was installed incorrectly during initial installation and start-up.

The problem was corrected and the analyzer returned to service.,

The "A" analyzer was inspected and it was determinbd that the pre-filter was correctly installed in it. Because the Unit I analyzer is made by Haye and the Unit II analyzer is made by Cumsto-Delphi, this problem is

([)

not applicable to Unit II.
