"On September 27, 2012, the Agency was notified by the licensee that the shutter on a Berthold nuclear gauge model number LB300L was found in the stuck open position during a routine inspection. The activity was not provided. The gauge shutter is stuck in the open position, which is the normal operating position. The licensee stated that the gauge does not create an increased exposure risk to any personnel. The manufacturer has been contacted and is scheduled to repair the gauge the first week in October.
"Additional information will be provided as it is received in accordance with SA-300."

| Event Text AGREEMENT STATE REPORT - STUCK SHUTTER ON PORTABLE ANALYZER
The following information was obtained from the State of New Hampshire:
"NH Radiological Health (Agency) was contacted by NH Licensee 461R, Prolerized New England Co., LLC, a part of Schnitzer Northeast, on April 16, 2010. Their Niton Model XLp-818 XRF Analyzer, Serial No. 7170, with a 30 mCi AM-241 source, reported an error message regarding the shutter when turned on. The instrument was surveyed and a high reading of 120,000 cps was detected. When the instrument was turned off, high readings were still detected. The Agency detected 10 mR/hr at the shutter.
"The instrument was leak tested and properly stored until it could be sent back to the manufacturer. The manufacturer received the instrument on May 26, 2010. The description of repairs was that they 'found large metal shavings in front end. Small shaving was jammed in the shutter motor gear causing shutter to remain opened. Removed metal shavings and tested shutter. Shutter working properly. Ran detector calibration and found resolution to be out of spec. Top and bottom housings are damaged. Strongly recommend upgrading to new LCD/Power board.' Unit required a wipe test.
"The licensee turned the instrument in and purchased a new one."
During a records review, it was determined that this event was not reported but should have been. No personnel overexposures occurred. |

"On October 11, 2012, at 1208 PDT, the Diablo Canyon Power Plant Unit 2 500kV line differential relay actuated, resulting in a unit trip. The unit trip actuated the turbine trip. With the turbine tripped and Unit 2 operating above the P-9 50% power permissive, a reactor trip was initiated from the reactor protection system. All plant equipment responded as designed.
"Unit 2 is stable at normal operating temperature and pressure. All power transferred to the plant startup source without incident. Condenser vacuum was maintained. The cause of the differential relay actuation is under investigation. Based on personnel observation it appears to have been initiated due to a flashover to ground across the phase 'A' main bank transformer capacitive coupled voltage transformer.
"PG&E will issue a press release regarding the Unit 2 trip.
"NRC Resident Inspectors have been informed of this event."
* * * UPDATE FROM DAN STERMER TO DONG PARK AT 2259 EDT ON 10/11/12 * * *
"This update to clarify the status of the auxiliary feedwater system during the above noted transient. Both motor driven pumps and the steam driven pump automatically started as expected.
"In addition, on October 11, 2012, at 12:26 PDT, the Diablo Canyon Power Plant Unit 2 turbine driven auxiliary feedwater pump was secured by plant operators manually closing the steam supply valve to the pump turbine. This action was performed in accordance with plant operating procedures after the operators had verified that the indicated steam generator levels were greater than the procedural requirement of 16%. However, because the steam generator low level bistables associated with the auxiliary feedwater actuation circuits had not yet cleared, the emergency safeguards actuation signal drove the steam supply valve back open, restarting the turbine driven auxiliary feedwater pump.
"Operators increased steam generator levels to clear the bistables and successfully reclosed the steam supply valve.
"The NRC Resident Inspector has been informed of this event."

"On 10/11/12 the Prairie Island Nuclear Generating Plant (PINGP) Security Force was conducting scheduled force on force security drills from 2000 to 2330 CDT. At 2107 CDT the Licensee was notified by the Wisconsin State Radiological Coordinator (SRC) that an intern had contacted the Wisconsin State Patrol Duty Officer to say they had taken cover at the plant and that there were sirens going off in the background. The intern did state that he did not know whether this was a real event or a drill.
"The Wisconsin State Patrol contacted the office of Wisconsin Emergency Management and the SRC. The SRC then contacted the PINGP Control Room and was informed by control room personnel that this was a security force-on-force drill. Xcel Energy Communications has notified other government agencies of this event via an email. No press release is planned at this time. This event is reportable per 10 CFR 50.72(b)(2)(xi)."

"On 10/12/12 at 0420 CDT the Unit 2 Steam Generator B Atmospheric Steam Dump Valve (ADV) spuriously opened while in automatic control. This resulted in indicated reactor power exceeding the FSAR analyzed value of 1810.8 MWt. Prompt operator action was taken and reactor power was restored to within limits in approximately four minutes. The operators placed the Atmospheric Steam Dump Controller to manual and closed the ADV successfully. This event is being reported under the criteria in 10 CFR 50.72 (b)(3)(ii)(B).
"All other plant systems responded as expected."

"On October 12, at 1535 CDT, Duane Arnold Energy Center made a voluntary report to the State of Iowa (Bureau of Radiological Health and Department of Natural Resources) and Linn County Public Health Department in accordance with the nuclear industry voluntary reporting criteria contained in NEI 07-07, 'Industry Ground Water Protection Initiative.' The subject of the report was a leak from the Condensate Storage Tanks' containment pit sump. The release occurred in an isolated area inside the plant property and has been terminated. Samples were taken and no regulatory limits were exceeded. During and following the leak, there was no impact to site worker or public health and safety.
"This report in being made in accordance with 10 CFR 50.72(b)(2)(xi), as a result of notification to offsite agencies.
"The Licensee has notified the NRC Resident Inspector."
Total amount leaked was estimated to be less than 100 gallons. |

"On October 12, 2012, at 2100 EDT, the Hope Creek Technical Support Center (TSC) ventilation system was removed from service to perform planned preventive maintenance on the system. The maintenance consists of minor maintenance to clean the intake louvers that supply outside air to the emergency filter unit (00-VH313), the supply unit fan (00-VH314) and the remote shutdown panel (RSP) supply unit fan (00-VH316). The removal of the ventilation potentially affects the TSC habitability during a declared radiological 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 25 hours and the TSC Ventilation will be returned to service at 2200 on October 13, 2012.

"At approximately 0320 CDT on 10/13/2012, Cooper Nuclear Station personnel identified portions of the onsite telephone system are not responding normally, following reports of a lightning strike in the vicinity of the meteorological tower. Personnel performed checks of onsite and offsite communications capability, and determined the normal method of contacting the state and local agencies would not function. Alternate methods were checked, and found to be only partially functional. This is considered to be a major loss of the offsite communications capability, and is reportable under 10CFR50.72(b)(3)(xiii).
"Alternate methods of contacting state and local agencies are available using working phones and the site cell phone system to obtain an offsite phone line and dial the direct line as listed in the emergency telephone directory. State and local agencies must be contacted individually. The capability to activate the ERO paging backup system per the implementing procedures is not affected by this condition.
"Communication personnel will respond to the site to correct the condition."
The licensee has notified the NRC Resident Inspector and will be notifying state and local agencies.
