The Perry Nuclear Power Plant will be taki … The Perry Nuclear Power Plant will be taking the ERDS out of service for scheduled maintenance. From approximately 0200 hours EDT, on June 10, 2008, until 2000 hours EDT, on June 10, 2008, personnel will be performing cleaning and inspection activities on the 120 VAC Emergency Response Information System (ERIS) Computer Power Center. During this planned preventive maintenance, the Integrated Computer System, the Safety Parameter Display System (SPDS), and the automatic mode calculation of the Computer Aided Dose assessment program (CADAP) will incur approximately two periods of unavailability of approximately two hours each. The unavailability periods are necessary to align a temporary power supply and reconnect the 120 VAC ERIS Computer Power Center upon completion of the activities.</br>The dose assessment function will be maintained during the brief out of service time periods by manual input of data into CADAP and, if required, by manual calculation. In the event of an emergency, plant parameter data will be orally transmitted to the facilities through the Status Board Ring Down circuit with back-up by the Plant Branch Exchange, the Off Premise Exchange, and various redundant intra-facility circuits throughout the emergency facilities. The ability to open and maintain on 'open line' using the Emergency Notification System will not be affected and will be the primary means of transferring plant data to the NRC as a contingency until the ERDS can be returned to service during the two periods of unavailability. This event is being reported in accordance with 10 CFR 50.72(b)(3)(xiii), as a condition that results in a major loss of offsite communications capability. A follow-up notification will be made when the activities are completed and the equipment is restored.
