Description of Event

On August 11, 1980 maintenance was completed on the Boric.(cid Transfer Pump 1-CH-P-2B.

The pump was operated to verify that the corrective maintenance was adequate. The pump was declared operable at this time without the performance of PT-15.2.

F,ric Acid Transfer Pump 1-CH-P-2B was placed in service on C Boric Acid Storage Tank on August 17,1980 whe21-CH-P-2C was removed from service for maintenance. At this time, '.he unit was in Mode 3 with at least two of three boron injection flow paths required by T.S. 3.1.2.2.

This event constitutes an inadequacy in the implementation of administrative controls and therefore, is reportable as per T.S. 6.9.1.9.c.

Probable Consequences of Occurrence The consquences of this event are limited since the pumps operability was verified on August 5,1980 just after maintenance and during recir-culation of the Boric Acid Storage Tank, and again on August 27, 1980 when the error was discovered. Therefore, the probable consequences would result from a lack of administrative controls (T.S. 6.9.1.9.c',

rather thas from the possible failure of the pump to perform its intended function.

Cause of Event

The primary cause of this event was an oversight by operations personnel. When the pump was initially returned to service after main-tenance, the unit was in Mode 5 wherein only one Boric Acid Transfer Pump is required, Therefore, pump 1-CH-P-2B was not placed in service on the Boric Acid Storage Tank and was not tested as per PT-15.2.

When Modes were changed (Mode 3 on August 17, 1980) pumps 2A and 2C were operating as required.

When pump 2C was later removed for maintenance, the operations personnel placed pump 2B on recirculation of C Boric Acid Storage Tank not aware that the pump had not been tested as per PT-15.2

Immediate Corrective Action

When the review of maintenance was performed by the on-site QC group, it was noted that the test had not been done. The periodic test (PT-15.2) was immediately conducted with satisfactory results. Operations personnel were reinstructed on the operability requirements for safety related equipment.
