| Title | Failure to Translate Design Information into a Procedure |
| Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the failure to translate criteria from the atmospheric relief valve accumulator leakage calculation into proceduralized leakage criteria. Specifically, engineering personnel did not translate the calculated design basis leakage criteria and the required minimum pressure to start the test into the procedure. The licensee entered this in to the corrective action program as Condition Report 26771, and the licensee was developing plans to revise the leakage criteria in the procedure.
This issue was more than minor because it affected the design control attribute of the Mitigating Systems Cornerstone and affected the objective to ensure the reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, the issue is determined to have very low safety significance because the finding is not a design or qualification issue confirmed not to result in a loss of operability or functionality; did not represent an actual loss of safety function of the system or train; did not result in the loss of one or more trains of nontechnical specification equipment; and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program component because licensee personnel failed to take appropriate corrective actions to previously identified problems P.1(d) |
