Westinghouse Subsidiary Receives Notice of Non-conformance

In a letter dated 8 June, the regulator said that inspections carried out in April by its staff found that the implementation of Westinghouse’s QA program did not meet certain regulatory requirements. The letter was made public on 16 June. Specifically, the NRC inspection team determined that Westinghouse was not fully implementing its QA program in the area of corrective action associated with incorrect use of material for AP1000 passive residual heat removal heat exchanger (PRHR HX) lower support stiffener plates, identified in an earlier inspection.
