| Title | |
| Description | A Green self-revealing NCV associated with emergency planning standard 10 CFR 50.47(b)(4) was identified regarding inadequate indications for operators to determine if a threshold for an Alert Emergency Action Level (EAL) (OA7) declaration based on toxic gas concentrations immediately dangerous to life and health (IOLH) within a vital area had been met. Specifically, there were no meters (permanently installed or portable) available on site to measure Freon concentration, a toxic gas in high concentrations. This impacted the operator\\\'s ability to make an EAL declaration and operators had to rely on other indications such as personal ill effects from exposure. PPL entered this issue into its CAP as AR 1294109 and is evaluating the development of permanent corrective actions. This performance deficiency is more than minor because it was 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. This finding was similar to an example of a green finding evaluated using IMC 0609, Appendix B, Emergency Preparedness SOP, Sheet 1, Failure to Comply. This finding is associated with a failure to meet or implement a regulatory requirement. The deficiency is not greater than Green because it did not result in the Risk-Significant Planning Standard Function being lost or degraded and was similar to an example of a green finding in that the EAL classification process would not declare any Alert or Notification of Unusual Event that should be declared. Since the declaration of Alert OAl based on toxic gas levels for Freon concentrations IOLH (defined as greater than 2000 ppm Freon) within a vital area could have been missed or delayed, this finding was considered consistent with the example provided and was determined to be of very low safety significance (Green). This finding is related to the cross-cutting area of Human Performance, Resources, because PPL did not ensure that equipment and other resources were available and adequate to assure safety. Specifically, PPL did not appropriately evaluate equipment necessary to effect a change to the emergency plan for an EAL classification related to toxic gasses in a vital area. PPL lacked adequate equipment to make an accurate EAL classification and had to rely on secondary means (personnel ill effects) for appropriately classifying a Freon leak in the Unit 1 RB that occurred on August 10, 2010. This was determined to be the most significant contributing factor to this issue. |
