| Event Text AGREEMENT STATE REPORT - OPERATING ARM FOR NUCLEAR GAUGE BROKEN
The following was received from the State of Texas via email:
"On February 28, 2014, the Agency [State of Texas] received a reciprocity request from a company from the State of Tennessee to perform emergency repairs on a Berthold model LB 8010 nuclear gauge containing a 20 milliCurie cesium-137 source at a generally licensed facility in Texas. The Agency [State of Texas] contacted the Texas licensee and asked if there had been a shutter problem with the gauge. The licensee stated on February 24, 2014, while they were moving the gauge from one location to another, one of their employees noted the operating arm on the shutter appeared bent. The employee attempted to straighten the operating arm and it broke off the gauge. The gauge was placed in the licensee's storage location. The licensee contacted the manufacturer who repaired the gauge shutter on February 25, 2014. The licensee stated no personnel received any significant exposure from the event. Additional information will be provided as it is received in accordance with SA-300."

"At 1628 EDT Nine Mile Point (NMP) Unit 2 experienced an actuation of the Alternate Rod Insertion (ARI) system which resulted in a reactor scram. Coincident with the scram, the Reactor Core Isolation Cooling (RCIC) system initiated.
"Prior to the event, maintenance personnel were working in the vicinity of a reactor vessel level instrumentation rack and may have agitated the common drain line of the transmitters. A prompt investigation is underway to investigate the incident.
"The actuation signal for the RCIC system was invalid because reactor vessel level did not reach level two and the actuation was not in response to actual plant conditions or parameters.
"The reactor scram is reportable in accordance with 10 CFR 50.72(b)(2)(iv)(B) as, 'Any event or condition that results in actuation of the reactor protection system (RPS) when the reactor is critical.'
"The event has been entered into the NMP corrective action program as CR-2014-001963.
"The NRC Resident Inspector has been notified."
The licensee has notified the State of New York.
The reactor is shutdown with all rods inserted. Decay heat is being rejected to the condenser and reactor water level is being maintained by condensate, feedwater, reactor water clean up, and control rod drive systems. |

"An extent of condition review identified that there were unfused 250 VDC circuits for the battery charger ammeters and the control circuits for various DC lube oil pumps which left the turbine building and went through the respective cable spreading room and up into the Control Room. These circuits are protected by 200 amp fuses and in some cases 100 amp fuses. The concern is that under the fire safe shutdown rules, it is postulated that a fire in one fire area can damage these circuits and cause short circuits without protection that would overheat the cables and possibly result in secondary fires in other fire areas where the cables are routed. The secondary fires could adversely affect safe shutdown equipment and potentially cause the loss of the ability to conduct a safe shutdown as required by 10 CFR 50 Appendix R.
"This condition is reportable as an 8-hour ENS report in accordance with 10 CFR 50.72(b)(3)(ii)(B) as an unanalyzed condition. Compensatory measures (fire watches) have been implemented for affected areas of the plant."
The licensee has notified the NRC Resident Inspector. |

"On March 11, 2014 at 0300 [EDT], the Hope Creek Technical Support Center (TSC) ventilation system was removed from service to perform planned maintenance. The removal of the ventilation potentially affects the TSC habitability during a declared emergency requiring activation. Appropriate compensatory measures are in place while the ventilation is out of service. The Emergency Response organization duty team has been notified of the maintenance and the possible need to activate the TSC in an alternate location. The ventilation system is scheduled to be out of service for approximately 78 hours."
The licensee will be notifying the NRC Resident Inspector and the Lower Alloways Creek Township. | |
