Technical Requirements Manual (
TRM) 3.4.a, Structural Integrity, requires the structural integrity of
ASME Code class 1, 2, and 3 components shall be maintained in accordance with the
ISI and Testing Programs.
Technical Specification 3.4.a.1 requires that the structural integrity of
ASME l Code class 1, 2, and 3 components be verified in accordance with the
ISI Program. Contrary to this, during the L2R12
RFO, the licensee discovered two
reactor water cleanup flow element
dissimilar metal welds were misclassified and, therefore not volumetrically examined. The flow elements received a system pressure test during L1R12 and L2R11 with no indication of leakage. The flow element was replaced during the U2 current
RFO with the U1 element to be replaced during the next outage. Based upon this, the violation was of very low safety significance. The licensee entered this issue into the
CAP as IR 865730
