Mr. James P.

O'Reilly LER No.82-027 Page Two November 19, 1982 DETAILED DESCRIPTION OF EVENT On October 21', 1982, with the Plant in Mode 3, one of the two

~

containment hydrogen monitors (Hydrogen Monitor "B") was inoperable due to a defective detector cell.

Technical Specification 3.6.5.1, " Containment Systems, Hydrogen Mcnitors", requires that two monitors be operable for Modes 1 and 2.

Because replacement parts could not be obtained prior to planned entry into Mode 2 on October 22, 1982, a Technical Specification change was requested by SCE&G and granted by the NRC to allow entry into Mode 2 for initial criticality with one monitor operable.

On October 22, 1982, the Plant entered Mode 2 under the subject Technical Specification Action Statement.

PROBABLE CONSEQUENCES No adverse consequences resulted from this event.

Hydrogen Monitor A was operable at the time of entry into Mode 2 and the requirements of this specification have been met since that time.

1 CAUSE(S) 0F THE OCCURRENCE The hydrogen monitor detector cell was inoperable.

IMMEDIATE CORRECTIVE ACTIONS TAKEN The hydrogen monitor detector cell was replaced.

Applicable Surveillance Test Procedures were performed, and the monitor was returned to service on October 26, 1982.

ACTION TAKEN TO PREVENT RECURRENCE Except for the normal surveillance requirements on the hydrogen monitors to demonstrate operability, the licensee plans no further action at this time.
