This is an eight hour report per 10 CFR 50 … This is an eight hour report per 10 CFR 50.72 (b)(3)(xiii). Calvert Cliffs Nuclear Power Plant (CCNPP) will be implementing a scheduled maintenance to the microwave radio system to improve reliability of the system at the Emergency Operations Facility (EOF), State and County facilities.</br>This work will require that the microwave radio system at the EOF be removed for a period of approximately 6 to 8 hours. During this time, the following systems will be impacted for the duration of maintenance:</br>1. The plant's (e.g., Control Room, Technical Support Center (TSC), Simulator) Dedicated Offsite Agency telephones will be out of service. (EOF's system will continue to function)</br>2. 800 MHz desk set radios at the EOF only will be out of service.</br>3. 153.44 MHz frequency at the EOF only will be out of service. (backup for MEMA and MDE)</br>4. MIDAS Terminal (Meteorological Data) located in the Dose Assessment Office at the EOF will be out of service.</br>5. TSC Computer data transfer to the EOF only will be out of service.</br>Once the scheduled maintenance starts the systems (listed above) can be returned to service within 1 hour. </br>Should an emergency be declared during this period, the Control Room will continue to have the capability to make the notification to the offsite agencies using the direct line for the appropriate agencies. The Emergency Preparedness communications procedure provides a chart listing the communication devices available and the order in which the process is to be implemented. MIDAS (Meteorological Data) will continue to be operational at the site and can be obtained by contacting the Control Room or TSC. The ERPIPs also provide a backup process and the instructions necessary for the EOF Dose Assessment Office to obtain Meteorological Data. Plant data can be obtain from the CR or TSC and will continue to be downloaded from the plant computer to the ERO SharePoint site. </br>All work associated with this microwave radio maintenance will be performed in an expeditious manner consistent with the goal of minimizing unavailability of the systems listed above. A test of all systems will be performed at the completion of the maintenance.</br>All EOF responders and Control Room personnel have been briefed on this work and expected contingent actions.</br>This job will start on Wednesday, December 29, 2010 at approximately 8:00 am. We anticipate that all work will be completed by 4:00 pm on the same day, including testing of the system. We will provide a notification update upon completion of the job.</br>The licensee informed the NRC Resident Inspector. Licensee will also notify state and local governments.</br>* * * UPDATE FROM DAN GENEVA TO JOE O'HARA AT 1405 ON 12/29/10 * * *</br>Communications are back in full service as of 1220 on 12/29/10.</br>Notified R1DO(Hansell)f 1220 on 12/29/10.
