"On 8/29/11, Monticello Nuclear Generating Plant's Technical Support Center (TSC) power supply will be isolated to perform a planned maintenance activity. The maintenance activity requires implementation of compensatory measures to maintain TSC functions during the activity. The compensatory measures include having the Emergency Director report to the Control Room and co-locating the remaining TSC staff at the EOF should an event be declared requiring ERO activation. The ERO has successfully previously demonstrated the ability to implement these compensatory measures. The maintenance activity is scheduled to be completed with the TSC returned to full functionality by the end of the dayshift on 8/29/11. The site Emergency Response Organization has been notified of the maintenance activity and instructed on the planned compensatory measures to be implemented during the activity. The licensee has notified the NRC Resident Inspector."

"At 1200 hours 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."
* * * UPDATE AT 2152 EDT ON 8/29/11 FROM MILLER TO HUFFMAN * * *
The licensee reports that the ERDS server replacement maintenance has been completed and ERDS capability was re-established at 2147 EDT on 8/29/11. The licensee will notify the NRC Resident Inspector. R2DO (Widmann) notified. | |
