Title | Emergency Response Data System Out of Service for Maintenance |
Event Description | At 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br /> on 08/29/11, the ERDS (Emergency Response Data System) was removed from service for a planned maintenance outage on a site network server. The duration of work, which affects ERDS for Brunswick Unit 1 and Unit 2, is expected to be approximately four (4) hours. Since the ERDS will be unavailable during this maintenance activity, this is considered a Loss of Emergency Assessment Capability and reportable under 10 CFR 50.72(b)(3)(xiii). An update will be provided when the scheduled work has been completed and ERDS has been restored.
ERDS is a direct near real-time electronic data link between the licensee's onsite computer system and the NRC Operations Center that provides for the automated transmission of a limited data set of selected parameters. ERDS supplements the existing voice transmission over the Emergency Notification System (ENS) by providing the NRC Operations Center with timely and accurate updates of a limited set of parameters from the Brunswick Plant installed onsite computer system in the event of an emergency. During the time ERDS is unavailable, emergency plan contingency measures are in place to transmit data, if required. The NRC Senior Resident Inspector will be notified of this evolution and the planned return to service of the system.
