| Title | Inadequate Instrumentation to Implement EALs for Unplanned Radiological Effluent Release |
| Description | The inspectors identified a Green NCV of 10 CFR Part 50.54 q and 50.47(b)(4) because PPL did not have adequate instrumentation to assess and determine if an abnormal radiological effluent release was in progress such that the EAL classification process would declare an Alert accurately and in a timely manner. Specifically, the maximum range for the liquid radwaste discharge radiation monitor was inadequate to ensure the meter was onscale when the threshold value of 200 times the alarm setpoint established by the discharge permit was reached. The finding was more than minor because it is associated with the Emergency Preparedness (EP) cornerstone attribute of Facilities and Equipment, and affected the cornerstone objective of ensuring that a licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. Specifically, the effective range for the liquid radwaste discharge monitor was insufficient to ensure a timely and accurate EAL classification could be made. Using IMC 0609, Appendix B, Section 5.4, the finding is of very low safety significance because the finding was determined to be an example of an ineffective EAL, such that an Alert would be declared in a degraded manner. This finding is related to the cross-cutting area of Pl&R - CAP because PPL did not thoroughly evaluate problems such that the resolutions address the causes and extent of conditions, to include properly classifying, prioritizing and evaluating for operability. Specifically, PPL failed to appropriately evaluate the extent of condition from similar NCVs issued in November 2008 and 2010 regarding inadequate instrumentation to support EAL declarations. |
