| Title | Inadequate Assessment of ECCS Room Cooler Fan Motor Bearing Nonconforming Condition |
| Description | A finding of very low safety significance and associated NCV of Technical Specification (TS) Section 5.4.1.a, associated with Regulatory Guide 1.33, Revision 2, Appendix A, Section 9, was identified by the inspectors when the licensee failed to adequately evaluate a condition adverse to quality prior to the maintenance activitys Environmental Qualification (EQ) Drop Dead Date (DDD). Specifically, the licensee failed to evaluate the Emergency Core Cooling System (ECCS) room cooler fan motors as operable but non-conforming prior to the EQ DDD as required by Duane Arnolds Preventive Maintenance Program procedure. The licensee entered this condition into their CAP as Corrective Action Process document 060543, and declared the equipment operable but non-conforming. This issue is more than minor because the finding was associated with the Mitigating Systems Cornerstone attribute of equipment performance and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesired consequences. Specifically, the failure to correctly assess the ECCS room cooler fan motor bearings as nonconforming with their EQ calculation of record had the potential to impact the availability and reliability of the ECCS room coolers. The inspectors evaluated the finding using the SDP in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of findings, Table 4a, for the Mitigating Systems Cornerstone. Because the finding was a qualification deficiency confirmed not to result in a loss of operability or functionality, the finding screened as Green. This finding has a cross-cutting aspect in the Problem Identification and Resolution (PI&R) component of CAP, because the licensee did not properly classify, prioritize, and evaluate for operability a condition adverse to quality P.1(c). Specifically, the Engineering and Operations Departments failed to classify the ECCS room cooler fan motors as operable but nonconforming. (Section 1R15) |
