The inspectors identified issues related to the corrective actions associated with 1-SWMOV- 103D,
SW supply to D RS Hx isolation valve, exceeding as left containment type C test leakage rate criteria on a previous occasion. Specifically, the inspectors noted that on April 1, 2006 the as left containment type C test result for 1-SW-MOV-103D was a 40 standard cubic feet per hour (scfh) leakage rate, as documented in Plant Issue N- 2006-1943. Although this plant issue was subsequently closed to work completed on
WO-00740175-01, the inspectors determined that annotations within the
WO indicated that no maintenance was performed. The inspectors reviewed 1-PT-61.3, Containment Type C Test, Rev. 26 One Time Only-1 which documented the as found and as left leakage rate for 1-SW-MOV-103D as zero. The inspectors noted that no remarks were made regarding the previous leakage rate issue documented in Plant Issue N-2006- 1943. On September 9, 2007 the inspectors noted that 1-PT-61.3 documented the as found containment type C test leakage rate for 1-SW-MOV-103D as greater than 257 scfh, which is in excess of the acceptance criteria. The licensee documented this problem in CR 019499, Rev. 0, 1-SW-MOV-103D Failed Type C Test (1-PT-61.3) Unmeasurable. The inspectors identified the issues relating to corrective action as an unresolved item (
URI) pending additional information from the licensee. This
URI is designated
05000338/2007004-03, Containment Type C Test and Corrective Maintenance Evaluation
