| Event Text AGREEMENT STATE REPORT - FIXED GAUGE WITH SHUTTER STUCK IN OPEN POSITION
The following Agreement State Report was received from the State of Louisiana via email:
"The RSO [Radiation Safety Officer], called to report that a gauge installed on a process at the licensee's Westlake, LA facility, had a shutter malfunction. The gauge is installed on a routing process for material at the facility. The gauge shutter is stuck in the open position.
"The Gauge is a Berthold Technologies, Model: Berthold Systems, LB-330 utilizing a 12 mCi Cs-137 source, Model: Lab. Prof. Dr. Berthold Dwg. #2653.100-001. The source and gauge will remain on the process in operation until the Berthold Technician arrives over the weekend service the gauge. This will be either make the necessary repairs to the shutter or remove the gauge from service and perform the disposal. Due to the age of the gauge, if it cannot be repaired, disposal is the resolution. This will be determined by the Berthold personnel performing the repair. The service order request has the repairs scheduled to be made over this weekend.
"There are no exposure or health and safety issues involved with this event. The gauge and rod source will remain installed on the functioning process. The resolution of the situation will be directed by the ability to be repaired or if the gauge should be de-installed and sent for disposal.
"The corrective action: Will be determined by the ability of the Berthold Technician to repair the shutters on the gauge or if the gauge needs to be de-installed and sent for disposal. The repairs and or corrective actions will be determined by a site visit and assessment by Berthold Technologies."
The State of Louisiana considers this event to be closed.

At 0147 EST on 1/25/16, the 'B' Reactor Coolant Pump (RCP) tripped offline. This caused a reactor trip on low coolant flow. As expected, the Aux Feedwater System (AFW) initiated on the reactor trip. The trip was uncomplicated and the plant is currently shutdown in Mode 3 with a normal electrical lineup and decay heat is being removed via steam dumps to the condenser. The cause of the 'B' RCP trip is under investigation. A containment entry is planned for dayshift on 1/25/16 to inspect and troubleshoot the 'B' RCP.

At 0315 EST on 1/25/16, Calvert Cliffs Unit 1 was manually tripped from 10 percent power due to elevated condenser sodium levels. All systems responded per design. Main Feed was secured and auxiliary feed water was initiated. The elevated sodium levels are believed to be due to a condenser tube leak. The reactor is currently shutdown and stable in Mode 3 and will remain in Mode 3 until repairs are effected. Unit 2 was not affected and remains at full power.

"This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability.
"This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) as the discovered condition affects the functionality of an emergency response facility.
"A condition impacting functionality due to a loss of cooling of the TSC (Technical Support Center) Ventilation system was discovered on 1/25/2016. At 1030 [EST], maintenance personnel reported the compressor local power breaker was tripped open and that all 3 phases of the compressor indicated grounded. Maintenance will begin repairs as soon as parts are made available. Estimated time to repair is unknown at this time.
"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. If relocation of the TSC becomes necessary, the Emergency Coordinator will relocate the TSC staff to an alternate location in accordance with applicable emergency plan implementing procedures. The Emergency Response Organization team will be notified of the condition and the possible need to relocate during an emergency. This condition does not affect the health and safety of the public or station employees. The NRC Resident Inspector has been notified." | |
