The inspectors identified a Green
NCV of 10 CFR Appendix B, Criterion V, Instructions, Procedures, and Drawings, because
PSEG did not adequately follow
Generic Letter (GL) 89-13 program procedure steps for performing inspections of the safety-related
SW piping and components. Specifically, certain American Society of Mechanical Engineers (
ASME) Nuclear Class III pressure retaining components were not inspected during
SW system internal pipe inspections, as required by
ER-AA-340,
GL 89-13 Program Implementing Procedure, Revision 8, during
SW system internal pipe inspections. Consequently, protective internal coating degradation on the 21
SW supply
header two-inch branch connection was not identified and corrected, which resulted in
through-wall leakage and significant weld material loss due to corrosion.
