Title

Failure to Analyze for Associated NON-SAFETY Circuits Which Could Produce Transients Due to Potential Fire Induced Spurious Operation

Description

The licensees analyses for associated circuits was limited to the emergency power system and did not include associated non-safety circuits. The nonsafety associated circuits could produce transients due to potential fire induced spurious operations that were not considered by the licensee in their Safe Shutdown Analysis. Although the licensee had not analyzed for associated non-safety circuits, there were no specific examples of associated non-safety circuits identified by the team. A non-cited violation of 10 CFR 50, Appendix R, Section III.G.2, was identified.
