Kalyanam Backup PM, Comanche Peak ACCEPTANCE REVIEW RECOMMENDATION: UNACCEPTABLE WITH OPPORTUNITY TO SUPPLEMENT The staff has performed an acceptance review using the guidance of LI C-109, Revision 1, "Acceptance Review Procedures." The licensee's reliance on fire risk analysis approaches of 1994 and earlier does not reflect current fire risk analyses approaches, and consequently fire risk issues from the latest methods. Based on applications using the latest fire PRA methods, fire risk is a significant contributor to plant to tal CDF and can have a significant im pact on the electrical distribution system. The licensee has not demonstrated that fire risk is an insi gnificant contributor for this application. Thus, the staff conc ludes that the analyses performed to support this LAR is inadequate to justify that fire risks are insign ificant to the application, either in total risk or change in risk. In particular, the fire risk model app lied by CPNPP can lead to incorre ct quantification of those fire scenarios identified as import ant to the analysis, as well as omission of important fire scenarios. In order to address this shortcoming, the licensee must provide an analysis cons istent with current fire risk analysis methods, meeting the necessary quality for the application and peer review expectations as identified by RG 1.200 Revision 2, and t he endorsed ASME/ANS PRA St andard, RA-Sa-2009.}} | | : Tamera, The NRC staff has reviewed your application and concluded that the information delineated below is necessary to enable the staff to make an independent assessment regarding the acceptability of the proposed relief request in terms of regulatory requirements and the protection of public health and safety and the environment. |
