UNIT SHUTDOWNS AND POWER REDUCTIONS C^CKET NUMBER: 50-382 UNIT NAME: WATERFORD 3 DATE OF REPORT: JULY,1994 l COMPLETED BY: T.S. BECKER TELEPHONE: 504-739-6683 REPORT FOR JUNE.1994 Type Method of Shutting ,

F = Forced Duration Down the Reactor or Cause, Comments and Number Date S = Scheduled (Hours) Reason (1) Reducina Power (2) Corrective Actions 94-03 940612 F 0.0 H 5 A Reactor Power Cutback was initiated due to a Turbine trip. The Turbine tripped on an invalid 2 out of 3 logic for MSR A2 High Level. The cause of the invalid High Level alarm was a failure to replace insulation on the sensing line for the MSR level switches. The reduced insulation in association with large amounts of rain caused the water level to rise in the float chamber which caused the level switches to actuate.

The sensing lines for the MSR level switches have been insulated.
