Due to a power outage offsite, the Davis-Besse Nuclear Power Station has experienced a loss of offsite communications capability, which is reportable within eight hours under
10 CFR 50.72(b)(3)(xiii). A loss of a minimum of two of three available telephone system pathways constitutes a loss of offsite communications capability under Davis-Besse site specific requirements (DBRM-RC-0001 R01 Attachment 10). As of 2012 on February 13, 2007, two of the three telephone pathways were unavailable. Full telephone service was restored at 2214 on February 13, 2007.
Due to the loss of the telephone systems, the site also lost the capability to page the Emergency Response Organization via the Computerized Automated Notification System (CANS) in the event of an emergency declaration. However, the site retained the ability to group page the Emergency Response Organization via alternate means. In addition, due to an ongoing snow storm, the site has elected to augment on-shift personnel with selected key Emergency Response Organization personnel.
The Emergency Notification System is currently available.
The licensee informed the State of
Ohio, local authorities and the NRC Resident Inspector.
