MR Number: 1-99-0026 Nine Mile Point 1 Date: 07/26/99 Lycoming,New York SRI PC Dockets: 50-220 BWR/GE-2 Subject: AUTOMATIC SHUTDOWN DURING POST-MAINTENANCE TESTING OF THE TURBINE GENERATOR MECHANICAL PRESSURE REGULATOR Reportable Event Number: 35954 Discussion: At 3:58 p.m. on July 23, 1999, Unit 1 automatically shutdown from 100% reactor power on a high flux signal. All safety systems responded as designed; however, both motor-driven feedwater pumps tripped on low suction pressure following their automatic start. The feedwater pumps were promptly restarted by control room operators and functioned properly for the duration of the event. The licensee is conducting a review of the feedwater system design to ensure optimum system response to this and similar plant transients. The cause of the high flux signal was large pressure oscillations due to the malfunction of the turbine generator mechanical pressure regulator (MPR). The maintenance staff was conducting post-work testing on the MPR when the regulator malfunctioned. Detailed examination of the MPR over the weekend identified the malfunction to be attributed to internal contamination of the "bean" control valve (feedback fine adjustment to the pressure sensing bellows) with a lubricant. As of 8:00 a.m. this morning, the unit was in Cold Shutdown. Regional Action: The resident inspectors monitored the licensee's recovery efforts and plan to review the event root cause determination and corrective actions prior to unit restart.
