Alert

Due to a lapse in appropriations, the NRC has ceased normal operations. However, excepted and exempted activities necessary to maintain critical health and safety functions—as well as essential progress on designated critical activities, including those specified in Executive Order 14300—will continue, consistent with the OMB-Approved NRC Lapse Plan.

REACTOR POWER EXCEEDED FSAR ANALYZED VALUE

"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."

The licensee has notified the NRC Resident Inspector.

* * * RETRACTION FROM MARY SIPIORSKI TO VINCE KLCO ON 12/04/12 AT 1544 EST * * *

"This notification is being made to retract Event Notification EN #48402 which reported power exceeding the FSAR analyzed value of 1810.8 MWt due to a spurious opening of an Atmospheric Steam Dump Valve. While 1810.8 MWt is the normal PBNP [Point Beach Nuclear Plant] full power value without consideration to uncertainties, subsequent reviews show that the peak power level reached during the event was bounded by FSAR analyzed events. Additionally, the opening of the valve is an Anticipated Operational Occurrence, described and analyzed in the FSAR.

"The power excursion during the event was below excursions evaluated in the FSAR. The event was analyzed and plant safety was not significantly degraded. Therefore, the event does not meet the criteria of 10CFR50.72(b)(3) and NextEra Energy Point Beach retracts Event Notification EN #48402."

The licensee notified the NRC Resident Inspector.

Notified the R3DO (Pelke).

PROCESS INSTRUMENT SHUTTER FAILURE

During a routine semiannual periodic inspection, a process gauge with a 15 milliCurie Cs-137 source was identified to have a stuck shutter. The gauge was an Ohmart Model SHF1-A45, S/N 0923GK. The instrument is permanently installed on a distillation column about 30 - 35 ft. from the ground. The integrity of the gauge is fine. Surveys indicated that radiation levels surrounding the gauge were less than 1 millirem per hour.

The same issue involving this specific gauge was reported previously in EN #46913.

The licensee plans on having the gauge repaired by the manufacturer.

ITEMS RELIED ON FOR SAFETY ASSOCIATED WITH THE DRY SCRAP RECYCLE FURNACE IMPROPERLY ANALYZED

"During a [Global Nuclear Fuels] GNF-A review of the Fuel Manufacturing Operation (FMO) Integrated Safety Analysis (ISA), it was determined at 1:30 PM yesterday (12/3/12) that Items Relied on for Safety (IROFS) associated with the Dry Scrap Recycle furnace operation were improperly analyzed in the ISA. Although criticality controls associated with preventing moderation intrusion exist and these controls remained in place, they were not sufficiently independent to meet performance requirements.

"At no time was an unsafe condition present. The affected equipment has been shut down. An investigation is continuing which will provide additional corrective actions and extent of condition.

"While this did not result in an unsafe condition, this event is being reported pursuant with the reporting requirements of 10CFR70 Appendix A (b)(1) within 24 hours of discovery."

The licensee will notify state and local governmental agencies and has notified the onsite NRC Inspectors.

LICENSEE NO LONGER HAS CONTROL OF EMERGENCY SIRENS

"At time 0942 [CST] telecommunications technicians reported to the Main Control Room that the site no longer has the ability to control offsite sirens. This was apparently caused by lightning strike in the area prohibiting the ability of the siren control computers to communicate with the sirens. This lost capability to alert a large segment of the population for one hour (by sirens and/or tone alert radios) requires a report per 10 CFR 50.72(b)(3)(xiii).

"Technicians are currently attempting to repair and correct this issue by moving another computer to the affected radio repeater in an effort to reestablish control of offsite sirens.

"At time 1057 the station began contacting offsite sirens agencies including the Louisiana Governor's Office of Homeland Security & Emergency Planning as well as all parishes within the 10 mile EPZ in order to initiate contingency actions for this issue. All agencies were notified as of time 1125. This constitutes a reportable notification of offsite agencies in accordance with 10 CFR 50.72(b)(2)(xi).

"Plant status remains Mode 1, 100% power, with no grid restrictions to report or radiological releases in progress. A follow up notification will be made to the NRC after the ability to control offsite sirens is restored."

Contingency actions are in place until the sirens are restored.

The licensee notified state and local governmental agencies as well as the NRC Resident Inspector.

TEMPORARY EMERGENCY OPERATING FACILITY ESTABLISHED FOR PLANNED OUTAGE

"In support of the planned upgrades to Crystal River Unit 3's Emergency Operations Facility's (EOF) heating, ventilation and air conditioning (HVAC) system, on Dec. 4, 2012, at 1200 hours Eastern Standard Time a temporary EOF has been established and declared operational. The temporary EOF is located adjacent to the primary EOF and remains outside the 10-mile Emergency Planning Zone. The temporary EOF meets the functional requirements of the primary EOF. During the establishment of the temporary EOF, there was no loss in the functionality of the EOF. If an emergency requiring EOF activation occurs, the temporary EOF will be staffed and activated using emergency planning procedures. The Emergency Response Organization has been briefed on the use of the temporary EOF. Readiness of the temporary EOF has been confirmed by a facility walkdown using existing procedures. This condition has no adverse affect on the public's or employees' health and safety. The EOF HVAC system is scheduled to be out of service for approximately four months.

"The NRC Resident Inspector has been notified,"
