TABLE 1 ITEMS WITH FLAWS OR RELEVANT CONDITIONS THAT REQUIRED EVALUATION FOR CONTINUED SERVICE Examination Category and Item Description Evaluation Description Item Number E-A Moisture Barrier Degradation AR02421997 and AR02422598 E1.30 Discovery: Several areas were identified damaged on the moisture barrier located on the 14' elevation.
During the repair phase of the moisture barrier, water was observed to be flowing out of the containment moisture barrier and pooling on the 14-foot elevation of the containment building. Chemical analysis confirmed that water in the moisture barrier was borated water. The source of the borated water was either from the refueling cavity or the spent fuel pool (SFP). The water was pumped from the moisture barrier after cavity drained down.
==
Conclusion:==
An engineering analysis requested the entire moisture barrier to be removed, washed, and left removed to allow the joint to dry during the current run cycle. The moisture barrier will be replaced during PTN 4-34. The repair task are included in WO40821680.
