| Title | Fort Calhouns Station\'S Ability to Classify Components AS Safety-Related |
| Description | The team found it difficult to determine how the licensee identified SSCs important to safety as required by 10 CFR Part 50, Appendix B, Criterion II. The team noted that several recent performance deficiencies have been identified by the NRC for not classifying SSCs as safety-related based on the safety function being performed. The team determined the licensees causal analysis to date for these issues was inadequate. Consequently, during the on-site inspection, the team questioned the classification of various SSCs which appear to meet the definition of safety-related, but have not been designated as such by the licensee. 10 CFR Part 50.2, Definitions defines safety-related SSCs as, ...those structures, systems, and components that are relied upon to remain functional during and following design basis events to assure: (1) the integrity of the reactor coolant pressure boundary; (2) the capability to shut down the reactor and maintain it in a safe shutdown condition; or (3) the capability to prevent or mitigate the consequences of accidents which could result in potential offsite exposures comparable to the applicable guideline exposures set forth in 10 CFR Part 50.34 (a)(1) or 10 CFR Part 50.100.11 of this chapter, as applicable. The team determined that the licensee may not have identified all the SSCs important to safety to ensure the controls of 10 CFR Part 50, Appendix B are applied. Additional review and follow up will be required to determine if this issue represents a performance deficiency or constitutes a violation of NRC requirements. This issue is identified as URI 05000285/2013008-22, Fort Calhoun Stations Ability to Classify Components as Safety-Related. |
