TECHNICAL SUPPORT CENTER VENTILATION OUT OF SERVICE FOR PLANNED MAINTENANCE
"A planned maintenance evolution at the Oyster Creek Generating Station has removed the Technical Support Center (TSC) ventilation system from service. The TSC ventilation system will be rendered non-functional during the course of the work activities. The TSC ventilation is expected to be out of service for approximately fourteen hours and will return to service at approximately 2200 [EDT] March 28, 2013.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures.
"This notification is being made in accordance with 10CFR50.72(b)(3)(xiii) due to potential loss of the TSC. An update will be provided once the TSC ventilation has been restored to normal operation."
The licensee informed the NRC Resident Inspector.
* * * UPDATE FROM ERIC SWAIN TO HOWIE CROUCH AT 1245 EDT ON 3/29/13 * * *
The TSC ventilation system was returned to service at 1240 EDT. The licensee has notified the NRC Resident Inspector.
