NRC CAL – NOV (White)

On April 13, 2018, the NRC issued a Notice of Violation to FirstEnergy Nuclear Operating Company (FENOC) for a violation of Title 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion V at Davis-Besse Nuclear Power Station, associated with a White Significance Determination Process finding. Contrary to the requirements, FENOC failed to assure that activities affecting quality were prescribed by documented instructions, procedures, or drawings. Specifically, FENOC failed to provide appropriate instructions to calibrate the turbine bearing oil sight glasses for the Auxiliary Feedwater (AFW) pumps. This failure resulted in failure of the inboard turbine bearing on the number 1 AFW pump due to low bearing oil levels when the pump was tested in September 2017. Additionally, there are associated violations of Technical Specification 3.7.5, "Emergency Feedwater," which requires three trains of emergency feedwater available at power or restored to operable within 72 hours and plant shutdown if the 72 hour requirement cannot be met.
