Per procedure, an RCS leak rate determination was commenced and completed as of 1629 hours, 12/8/05 (identified = 0.032gpm, unidentified = 0.254gpm, total = 0.286gpm). While making preparations for a containment entry for leakage inspection, a second leak rate (determination) was completed at 2020 hours, 12/8/05 (identified = 0.070gpm, unidentified = 0.267gpm, total = 0.337gpm). At 2240 hours, 12/8/05, the team performing the containment leak inspection reported no leakage identified outside the bioshield. Another leak rate (determination) was completed at 0245 hours, 12/9/05, the team performing the containment leak inspection reported that by using a robotic camera, water was observed coming down the inside wall of the bioshield in the area of loop 2.
