A Self-Revealing Non-cited Violation of Te … A Self-Revealing Non-cited Violation of Technical Specification 3.1.3.1.b requirements was identified on Unit 3 when position indication for two rod control cluster assemblies (RCCs) drifted out of tolerance with the associated rod group position indication. Contrary to technical specification requirements, rod positions were neither re-aligned with the group counter nor was reactor power reduced to less than 90 percent within the allowed one hour action time with a potential consequence of challenging accident analysis assumptions. The issue was documented in the corrective action program as CR 2010-14724</br></br>The finding was more than minor because if inaccurate rod position indication was left uncorrected, there was a possibility of an adverse affect of an actual rod misalignment beyond that assumed in accident analyses. The Initiating Events cornerstone was affected because rod position alignment assures that accident analysis assumptions are maintained. The inspectors evaluated the finding using NRC Inspection Manual 0609, Attachment 0609.04, Initial Screening and Characterization of Findings and classified the finding of very low safety significance (Green) using the Transient Initiator tool. The cross-cutting aspect of Human Performance, Decision Making (H.1.a) was affected when supervisory personnel did not implement their roles and authorities to ensure safety by implementing Technical Specification requirements.ting Technical Specification requirements. +
