At 2124 hrs on 2/3/06, a containment leak … At 2124 hrs on 2/3/06, a containment leak inspection team reported pressure boundary leakage (RCS) at a welded connection on a 3/4" bypass line around the RHR loop suction valve 2HV8701B. Presently the unit is in Mode 3. Preparations are being made to commence cooldown to Mode 5 for repair of the leak.</br>Unit 2 was taken from 100% RTP to approximately 30% RTP beginning at 1200 hrs on 2/01/06 for repairs of an EHC leak on the main turbine front standard. The EHC leak was repaired and power ascension to 100 % RTP commenced at 2213 hrs on 2/01/06. Approximately 100 % RTP was reached on 2/3/06 at 0600 hrs.</br>Between 1900 hrs on 2/01/06 and 1600 hrs on 2/02/06, radiation monitor 2RE2562A went into Intermediate Alarm for short durations on three different occasions. Due to moving the plant, an accurate RCS leak rate could not be performed.</br>A containment entry was performed on the night shift 2/2/06 and again on dayshift 2/3/06. Utilizing a robot and camera, leakage was observed inside the bioshield in the area of RCS Loop #1. The source of the leak on both containment entries was inconclusive. At 1412 hrs on 2/3/06, a shutdown of Unit 2 was initiated to allow further investigation/repair of the leak inside containment.</br>Unit 2 was placed in Mode 3 at 1807 hrs on 2/3/06.</br>See also EN# 42194 for a similar incident.</br>The licensee notified the NRC Resident Inspector.ensee notified the NRC Resident Inspector. +
