Title | Design Changes Not Appropriately Approved by the Licensee |
Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, associated with the licensees failure to ensure that design changes were subject to design control measures commensurate with those applied to the original design and were approved by the designated responsible organization. Specifically, the licensee received a design level calculation from a vendor in support of service water pump C change out, but failed to appropriately review, accept and enter this calculation into their design basis. This issue was entered into the licensees corrective action program as Condition Report CR-CNS-2012-03634. The licensees failure to ensure that changes to the facility were subject to design control measures commensurate with those applied to the original design, and were approved by the designated responsible organization was a performance deficiency. The performance deficiency was determined to be more than minor because it was associated with the design control attribute of Mitigating Systems Cornerstone, and affected the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences, and is therefore a finding. Using Inspection Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to have very low safety significance (Green) because the finding: (1) was not a design or qualification issue confirmed not to result in a loss of operability or functionality; (2) did not represent an actual loss of safety function of system or train; (3) did not result in the loss of one or more trains of nontechnical specification equipment; (4) did not screen as potentially risk significant due to seismic, flooding, or severe weather initiating event. This finding had a cross cutting aspect in the area of human performance associated with the work practices component, because the licensee failed to adequately define and effectively communicates expectations regarding procedural compliance and personnel failed to follow procedures. Specifically, engineering department personnel failed to follow station procedures when receiving a new design basis calculation from a vendor. |
