The NRC performed the supplemental inspect … The NRC performed the supplemental inspection to assess the licensees evaluation and corrective actions regarding the inadequate maintenance and testing of the personal home alerting devices (PHADs), an integral part of the alert and notification system, to ensure that the design function of alerting essentially 100% of the public in the emergency planning zone could be met. This performance issue was previously characterized as having low to moderate safety significance (i.e. White) in NRC Inspection Report 50-334/02-003 and 50-412/02-003. During this supplemental inspection, performed in accordance with Inspection Procedure 95001, the inspector determined that the licensee performed a comprehensive evaluation of the inadequate PHAD maintenance and testing. First Energys evaluation identified the primary root cause of the performance issue to be the failure to administratively ensure that PHAD test procedures, acceptance criteria, maintenance programs and installation data were properly established and maintained. However, First Energy performed an extent of condition review which was not o sufficient scope, in that it focused on EP issues alone. Additionally, the effectiveness review, completed to assess the effectiveness of corrective actions, focused solely on the siren hardware changes and did not cover the human performance issues which contributed to inadequate PHAD testing and maintenance. Subsequent NRC review of a new extent of condition investigation documented in CA #24 to CR 02-02202 and effectiveness review documented in CA#12 to the same CR revealed that there were no remaining issues which would prevent the closure of the PHAD White finding.ent the closure of the PHAD White finding. +
