Title | Licensee-Identified Violation |
Description | Incorrect Emergency Event Classification Title 10 CFR Part 50.47(b)(4), Emergency Plans, states, in part, that a standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters, is in use by the nuclear facility licensee. Comanche Peak Nuclear Power Plant Emergency Plan Units 1 and Unit 2, Revision 38, Step 1.1.2.1 requires, in part, that at the onset of an event, the shift manager will assess, classify, and declare an emergency. Contrary to the above, on February 18, 2011, the shift manager classified and declared an Unusual Event without meeting specific emergency action level criteria. Specifically, the shift manager misclassified a 40 gallon per minute chemical and volume control system leak as identified reactor coolant system leakage greater than 25 gallons per minute resulting in the incorrect declaration of an Unusual Event. Using IMC 0609, Appendix B, Emergency Preparedness Significance Determination Process, Sheet 2, the finding was determined to have very low safety significance because the actual event implementation problem was associated with an Unusual Event. The NCV was documented the licensees corrective action program as Condition Report 2011-001876. |
