AGREEMENT STATE REPORT - CONTAMINATION EVENT
The following information was obtained from the State of Tennessee via email:
"On 12/10/12 at 4:30 pm EST, [the] RSO [at] Energy Solutions-Bear Creek called [the State of Tennessee] to report that last Friday, 12/7/12, a drum of DU shavings had been placed in Area 9 of the old ATG building and covered w/mineral oil. When [workers] came to work on 12/10/12, they noticed that the poly drum was completely gone, the shavings were on the floor, oil was on the floor and some of the shavings looked like ash. The poly drum had burned up and the drum/shavings and oil/ash/shavings were now on the concrete floor. There was no stack release. The stack samples were pulled and indicated less than MDA: < E-14 for U-238 and

PLANT VENT CONTINUOUS RADIATION MONITORS INOPERABLE
"This is a non-emergency notification. At 1804 PST on December 17, 2012, Diablo Canyon Unit 1 experienced a loss of plant vent continuous radiation monitors (RM) and redundant monitors 14/14R, 24/24R, 28/28R and 87. These radiation monitors are credited for Emergency Action Level (EAL) classification in the Diablo Canyon Emergency Plan. This event is reportable per 10 CFR 50.72(b)(3)(xiii) as described in NUREG-1022, Rev. 2. Compensatory measures of periodic sampling have been established in accordance with plant equipment control guidelines. Event classification can be performed by means of the sampling in accordance with plant procedures. Additionally, continuous radiation monitoring of the plant vent remains via high range radiation monitor RM-29.
"The cause of the loss of radiation monitors is not known at this time.
"This condition does not affect the health and safety of the public or the operation of the facility.
"The NRC Resident Inspector was informed."
* * * UPDATE AT 0948 EST ON 12/18/12 FROM DAVE GOUVEIA TO HUFFMAN * * *
The licensee determined that the flow element on the sampling pump for the radiation monitors had failed. At 0630 EST, the condition was repaired and the radiation monitors returned to service.
R4DO (Whitten) notified. |

60 DAY OPTIONAL TELEPHONIC NOTIFICATION OF INVALID PRIMARY CONTAINMENT ISOLATION SYSTEM (PCIS) ACTUATION
"This 60-day telephone notification is being made under reporting requirements specified by 10CFR50.73(a)(2)(iv)(A) to describe an invalid actuation of a containment isolation signal affecting more than one system.
"At 1920 on October 20, 2012, with the Duane Arnold Energy Center (DAEC) shut down for a preplanned refueling outage, an invalid Group 3 isolation on the 'A' side of the Primary Containment Isolation System occurred. Group 3 isolation signals were generated for Primary Containment Isolation Valves for Drywell and Torus Ventilation, and Purge, Containment Nitrogen Compressor Suction and Discharge, Recirculation Pump Seals, and Post Accident Sample System.
"This event was caused by failed components in the power supply circuitry for the 'A' Refuel Floor Exhaust Radiation Monitor.
"All equipment responded in accordance with the plant design. Specifically, all actuations were complete and successful.
"There were no safety consequences or impacts on the health and safety of the public. The event was entered into DAEC's corrective action program for resolution.
"The licensee notified the NRC Resident Inspector." |

PARTIAL LOSS OF EMERGENCY ASSESSMENT DURING PLANNED MODIFICATIONS
"Calvert Cliffs Nuclear Power Plant will begin a planned modification of the Unit 1 and Unit 2 Plant Process Computers (PPC's) and associated network infrastructure on December 18, 2012. This includes the Emergency Response Data System (ERDS) communication with the NRC Operations Center. This work will require the TSC, OSC and subsequently EOF to lose data flow from the plant data network for a period of approximately 36 hours. During this time, the following systems will be impacted for the duration of maintenance:
1. ERDS will be out of service.
2. Plant Data will not reach the TSC and OSC from the plant data network.
3. TSC Computer data transfer to the EOF only will be out of service.
4. Chemistry DAS remote monitoring capability will be lost.
5. Plant parameter data will not be available on the site's LAN network.
"Once the schedule maintenance starts, the systems (listed above) can be returned to service within 1 hour. Should an emergency be declared during this period, the Control Room will continue to have the capability to retrieve plant data inputs to assess plant conditions and perform core damage assessment. Control Room Emergency response personnel will use emergency response procedures (ERPIP 106) to disseminate plant parameter data to the effected Emergency Response Facilities. MIDAS (Meteorological Data) will continue to be operational at the site. Compensatory measures exist within the Calvert Cliffs Emergency Response procedures to provide plant data in the event of an actual Emergency to the NRC Operations Center until the ERDS can be returned to service."
The licensee notified the NRC Resident Inspector. |
