TECHNICAL SUPPORT CENTER (TSC) PLANNED MAINTENANCE ACTIVITY
"On 8/6/10 at 0700 CDT the Monticello Nuclear Generating Plant's [MNGP] Technical Support Center uninterruptible 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 previously successfully 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 8/6/10. 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. MNGP will notify the NRC upon completion of the activity restoring full TSC operability. This event is considered reportable per 10CFR50.72(b)(3)(xiii). The licensee has notified the NRC Resident Inspector."
The licensee will inform both State and local agencies.
