| Title | Incorrect Wind Direction on NARS Form |
| Description | A NRC-identified finding of very low safety significance and associated NCV of 10 CFR 50.47(b)(9) was identified for delayed corrective action without appropriate compensatory actions for a defective computer point that sends wind direction data to the plant parameter display system (PPDS). This defective computer point resulted in incorrect wind direction on a Nuclear Accident Reporting System (NARS) form transmitted to the State of Illinois as part of the declaration of an Unusual Event on May 19, 2010. Corrective actions included the restoration of the computer point for PPDS. Inspectors identified this performance deficiency had a cross-cutting aspect in Problem Identification and Reporting - Evaluation because although the non-functional computer point, R234, was identified in December 2009, the licensee failed to thoroughly evaluate, classify, and prioritize the condition of bad data from a computer point and assess how the condition affected PPDS (P.1(c))
This finding is more than minor because the performance deficiency matches an example of a Green finding from IMC 0609, Appendix B, Section 4.9, page B-20, Equipment or systems necessary for dose projection are not functional for longer than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> from the TIME OF DISCOVERY without compensatory measures, or corrective actions are inadequate or delayed. Using IMC 0609, Appendix B, Sheet 1, Failure to Comply Flowchart, the performance deficiency screened as very low safety significance, or Green. |
