On April 30, 2010, a Notice of Violation (NOV) was issued to FirstEnergy Nuclear Operating Company for a Severity Level III problem for the failure to implement: (1) 10 CFR 50.71 "Maintenance of records, making of reports" and (2) 10 CFR 50, Appendix B, Criterion III, "Design control." In July 1999, the licensee submitted a license amendment request to eliminate as found testing criteria by using the past data for double O ring data and was approved by the NRC. However, the licensee staff did not update this fact in their updated final safety analysis report. The licensee also changed from the double O ring design to a flat gasket design which did not have the same reliable history as the double O ring and failed to translate this fact into the licensing basis at time of installation.
