MR Number: 2-95-0010 Farley 1 Date: 01/17/95 Ashford,Alabama Dockets: 50-348 PWR/W-3-LP Subject: FOLLOWUP OF AUTOMATIC TURBINE TRIP/REACTOR TRIP DUE TO LOSS OF DC POWER TO TURBINE CONTROL SYSTEM Reportable Event Number: 28236 Discussion: At 0758 CST, January 13, 1995, Unit 1 of the Farley Nuclear Plant (FNP) tripped from 100 percent power after 264 continuous days online. This trip came as a result of a momentary loss of internal power to one of the digital processing units (DPU), in the Digital Electro-Hydraulic Control (DEHC) system, responsible for turbine overspeed protection. When the back-up DPU failed to pick-up fast enough, the main turbine tripped on a first out indication of "DEHC DC Power Failure." All plant systems and operations personnel performed well as observed by the resident staff. The reactor was stabilized in Mode 3. This reactor trip was similar to the sequence of events that occurred during the Unit 2 reactor trip of December 25, 1994. The licensee, in concert with the DEHC vendor (Westinghouse), has since conducted a wide range of diagnostic tests on the DEHC system and implemented certain modifications to enhance the DEHC system's ability to tolerate spurious power fluctuations. In addition, power supply components were replaced while shutdown. Unit 1 was taken critical at 0219 CST on January 17, 1995. Regional Action: Resident inspectors are monitoring the startup and main turbine testing activites. Contact: R. BERNHARD (404)331-4664 PRIORITY ATTENTION REQUIRED MORNING REPORT - REGION IV JANUARY 17, 1995 Licensee/Facility: Notification: Washington Public Power Supply System MR Number: 4-95-0008 Washington Nuclear 2 Date: 01/17/95 Richland,Washington Resident Inspector Dockets: 50-397 BWR/GE-5 Subject: INSTRUMENT AND CONTROLS TECHNICIAN TRANSPORTED TO OFF SITE MEDICAL FACILITY FOLLOWING ELECTRICAL SHOCK Reportable Event Number: N/A Discussion: On January 13, 1995, a licensee employee received an electrical shock from a 120 volts (ac) circuit. An instrumentation and controls technician was working in a back panel in the control room, and was disconnecting a hot power lead for leak detection instrumentation, when he received an electrical shock. The employee did not appear to be severely injured, but was transported to Kadlec Medical Center in Richland, Washington, as a precautionary measure. The licensee is conducting a safety investigation to determine the cause of the shock and to propose corrective actions. The licensee does not intend to issue a press release. Regional Action: The resident inspector and regional management are monitoring the licensee's action in response to this event. Contact: G. Johnston (510)975-0304 R. Barr (509)377-2627
