These indications were noted during the VT-3 visual examination of the moisture barrier (MB-3)

(azimuth 303-360 and 0-60) at SCV interface at the raceway floor. (Refer to drawing CISI-2000-C-59 for details.) The examination identified 9 locations with minor tears/open blisters the maximum length 1/2 inch and the maximum depth of 1/4 inch. The examination also identified minor debonding of the top edge of the moisture barrier to the SCV in 10 locations with a total length of approximately 20 inches with an approximate maximum depth of 1 3/4 inches. These tear indications on the moisture barrier may have been caused by the removal of the steel flashing for examination. The open blisters were caused by the application process for the moisture barrier. The lack of adhesion of the moisture barrier material at the top edge to SCV interface was due to surface preparation and minor shrinkage at these areas when the moisture barrier was replaced in Unit 2 Cycle 10 refueling outage.

The total depth of the moisture barrier is approximately 6 inches. The moisture barrier material at the top edge to SCV interface was removed down to sound adhesion between the SCV and the moisture barrier material. These debonding areas were determined to be minor due to the depth of the moisture barrier being approximately 6 inches. The exposed SCV at these areas was VT-3 examined, and there were no visible signs of active corrosion, any significant wall loss or gross degradation. The exposed SCV areas requiring recoating were recoated and VT-3 examined. The 9 areas identified as minor indications on the surface of the moisture barrier were removed to sound material. The removed moisture barrier material was filled with RTV and VT-3 examined. This minor debonding and surface areas has not affected the leak-tight integrity of the moisture barrier. These areas are normally inaccessible due to the stainless steel flashing and insulation. Based on the information above, the moisture barrier areas are not considered suspect and do not impact the structural integrity or leak tightness of the SCV. The moisture barrier areas are acceptable for continued service, and no further corrective action is required. Based on this information, there is no indication that an adverse condition exists in the areas examined or that an adverse condition would be present in inaccessible areas.

These indications were noted during the VT-3 visual examination of the moisture barrier (MB-3) at the interface of the SCV and raceway floor. The examination identified 9 locations with minor tears/open blisters with a maximum length of 1/2 inch and the maximum depth of 1/4 inch.

These tear indications on the moisture barrier may have been caused by the removal of the steel flashing for examination. The blisters were caused by the application process for the moisture barrier. The moisture barrier was replaced in Unit 2 Cycle 10 refueling outage.

The examination also identified indications consisting of minor debonding of the top edge of the moisture barrier at the Steel Containment Vessel (SCV) interface at 10 locations with a total length of approximately 20 inches with an approximate maximum depth of 1 3/4 inches. The debonding at these locations appeared to be lack of adhesion of the top edge of the moisture barrier to the SCV and minor shrinkage.

There were no visible signs of active corrosion on the SCV or that the moisture barrier had lost its leak tight integrity. The SCV at the moisture barrier areas examined did not show any significant wall loss or gross degradation. The examination identified minor indications on the surface of the moisture barrier, and also, the moisture barrier top edge at the SCV had several minor areas of debonding. However, upon further review, the moisture barrier had sound adhesion. The SCV areas were deemed to have minor corrosion in some of these areas. The moisture barrier areas with surface indications were removed to sound moisture barrier material.

The top edge of the moisture barrier material at the SCV interface was removed at the debonded areas to sound material where the moisture barrier adheres to the SCV. The SCV surface at the removed moisture barrier material was VT-3 examined. The VT-3 examination did not identify any significant degradation of the SCV liner. The areas requiring recoating were recoated and VT-3 examined. RTV was used to fill in at the removed moisture barrier material areas and was VT-3 examined. These areas are not considered suspect and do not impact the leak tightness of the moisture barrier or the structural integrity or leak tightness of the SCV. The component is acceptable for continued service, and no further corrective action is required. An additional section of the moisture barrier (MB-1) will be examined prior to or during the next U2C15 refueling outage. The moisture barrier was replaced in the U2C10 refueling outage. Moisture barrier section (MB-2) was examined in the U2C12 refueling outage and debonding was not identified. The component is acceptable for continued service and no further corrective action is required.
