Mr. James P.

O'Reilly LER No.82-057 Page Two January 11, 1983 DETAILED DESCRIPTION OF EVENT On December 13, 1982, with the Plant in Mode 1, the Turbine Building sump normal discharge flow path to the plant settling ponds was temporarily bypassed.

This was accomplished by an auxiliary pump and a fire hose.

The normal discharge flow path is monitored by Turbine Building Sump Radiation Monitor RM-L8.

As RM-L8 did not monitor the temporary discharge flow path, grab samples were taken during the discharge operation.

Technical Specification 3.3.3.8 addresses the Turbine Building sump radiation monitoring requirements.

PROBABLE CONSEQUENCES There were no adverse consequences resulting from this event as the applicable Technical Specification Action Statement was met.

More specifically, grab samples were taken as required with acceptable results.

CAUSE(S) OF THE OCCURRENCE This event is attributed to the fact that fireproofing repair work was being conducted in the Turbine Building.

Due to the lack of adequate controls, construction debris accumulated in the Turbine Building sump.

Upon activation, the sump pumps (XPP-104-A and B) became clogged, which rendered the normal flow path inoperable and necessitated a temporary flow path for the i

sump discharge.

IMMEDIATE CORRECTIVE ACTIONS TAKEN The immediate corrective action taken was to remove all debris from the Turbine Building sump in order to restore the normal discharge flow path monitored by RM-L8.

This was accomplished by December 15, 1982.

ACTION TAKEN TO PREVENT RECURRENCE This event has been reviewed with construction management and resulting tightened housekeeping controls will be established to prevent recurrences of this type in the future.
