MR Number: 3-95-0004 Clinton 1 Date: 01/09/95 Clinton,Illinois SRI BY LAN Dockets: 50-461 BWR/GE-6 Subject: MANUAL REACTOR SCRAM AND RESTART Reportable Event Number: N/A Discussion: At 10:33 p.m. (CST) on January 5, 1995, the operators manually scrammed the reactor due to the loss of control of feedwater heater levels. Due to leaking tubes in the 5B feedwater heater, the licensee was removing the "B" feedwater heater train from service. During the evolution, a pressure imbalance developed in the "A" heater train. This caused level control problems in the feedwater heaters. All systems responded as expected following the scram. The licensee plugged the defective tubes on the feedwater heater. At 11:02 a.m. on January 7, 1995, the turbine was placed on line to end the forced outage. Regional Action: The resident inspectors followed the licensee's recovery actions. Contact: B.

MR Number: 4-95-0004 South Texas 1 Date: 01/09/95 Wadsworth,Texas Senior Resident Inspector Dockets: 50-498 PWR/W-4-LP Subject: ISOLATION OF REACTOR COOLANT SYSTEM (RCS) LEAK Reportable Event Number: 28222 Discussion: This is an update to the licensee's courtesy Notification 29222. After using a robot camera to identify the source of the small RCS leak, the unit power was reduced to 35 percent to permit worker entry inside the biological shield. The leak was at a tubing union between an isolation valve (RC-061D) and Flow Transmitter FT-447. The root valve was closed to isolate the leak. The bistable associated with the flow transmitter has been placed in the tripped condition, resulting in 1 of 2 trip logic for Loop D RCS flow. The licensee plans to repair the union during the March 1995 refueling outage. At 8 a.m. on January 9, power was at 48 percent and was being raised to 100 percent. Regional Action: Routine resident followup inspection. Contact: Bill Johnson (817)860-8148
