Description | The inspectors identified a cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the failure of engineering personnel to translate the design basis maximum condensate storage tank temperature requirements into procedures to ensure the plant is operated within its design basis. This issue was entered into the licensees corrective action program as Palo Verde Action Requests 3289578 and 3289530.This finding is greater than minor because it is associated with the mitigating systems cornerstone attribute of equipment performance and affected the cornerstone objective of ensuring the availability and reliability of systems that respond to initiating events to prevent undesirable consequences. Using the Inspection Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the finding is determined to have very low safety significance since it only affected the mitigating systems cornerstone and did not represent a loss of system safety function. The cause of this finding had crosscutting aspects associated with corrective action component of the problem identification and resolution area in that engineering personnel failed to thoroughly evaluate problems such that resolutions ensured that the problems were resolved (P.1c) |
