AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA SOURCE UNABLE TO BE RETRACTED

The following information was provided from the State of Louisiana via facsimile:

"IRISNDT dispatched a radiography crew to Marathon Petroleum on September 5, 2012. The crew set up and began work around 6:30 am. The crew worked with a camera, associated equipment, and a collimator for hours before there was a problem. [At 1045 CDT] the source setup was about 15 feet up above the ground in the pipe rack when the source would not return into the shielded position. After several attempts to retrieve the source, the RSO was notified. The crew was instructed to secure the barricade at the 2 mR distance and maintain observing the area until the RSO could arrive. The RSO arrived and secured the source into the exposure device's shielded position.

"The equipment, QSA Global Delta 880, s/n# D6460, the source is s/n# 86363B ...Ir-192, last leak tested on 08/07/2012. The investigation concluded a gear in the crank assembly was damaged and it caused the drive cable to jam. The assembly was red tagged and removed from service. Event exposures were 29 mR [Radiographer Trainer], 6 mR [Radiographer Trainee] and 2.4 mR [RSO]."

LOSS OF ASSESSMENT CAPABILITY AT THE EMERGENCY OPERATIONS FACILITY

"At approximately 0100 hours EDT, on October 9, 2012, a low voltage circuit breaker in the Crystal River Unit 3 (CR-3) Emergency Operations Facility (EOF) tripped due to an electrical fault. The associated loads were powered by backup batteries until they depleted at approximately 1057 EDT. This condition resulted in the loss of dose assessment (RASCAL) and facility cooling capability.

"Dose assessment capability at the EOF was restored by 1335 EDT. During this event, RASCAL could be run from any plant computer outside of the EOF and the results conveyed back to the EOF. EOF ambient temperature is being monitored. An estimated completion time for chiller restoration has not been established. A follow-up notification will be provided when the chiller operation has been restored. This report is being made in accordance with 10 CFR 50.72(b)(3)(xiii).

"At no time was the public's or plant employees' health or safety at risk. Due to numerous backup systems, alternate methods were available to calculate dose projections, if required, and communicate the information to the EOF.

"The NRC Resident Inspector has been notified."

DISCOVERY OF AFTER-THE-FACT EMERGENCY CONDITION - UNUSUAL EVENT

"The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.

"On August 26, 2012, at approximately 1231 Mountain Standard Time (MST), some Auxiliary Operators located in the Palo Verde Nuclear Generating Station (PVNGS) Operations Support Buildings reported to the control room that they had felt an earthquake. The US Geological Survey (USGS) internet web page recorded several small earthquakes in the Salton Sea area of Southern California. The earthquake was not felt by the control room staff and no Seismic Monitoring System alarms were received. The event was evaluated and a determination was made at that time that the event did not meet the classification criteria for declaration of an Unusual Event per the PVNGS Emergency Plan. Similarly, at 1358, personnel again reported they felt motion in the Operations Support Buildings and the USGS reported an aftershock in Southern California. The event was similarly determined to not meet the classification criteria for declaration of an Unusual Event.

"There were no indications of any impact to plant equipment or site operations other than being felt by personnel in the Operations Support Buildings.

"During post event reviews, it has been determined that these events met the classification criteria for declaration of an Unusual Event for a seismic event as specified by the PVNGS Emergency Plan. No emergency situation exists at this time.

"The NRC Resident Inspector was informed of this notification."

The licensee notified Maricopa County and the State of Arizona.

UNANALYZED FIRE PROTECTION DEFICIENCIES

"On 10/9/12, at 16:30 PDT control room operators were questioned whether recently identified fire protection program deficiencies should have been reported to the NRC.

"On October 3 and October 8, 2012, DCPP [Diablo Canyon Power Plant] staff reviewing NFPA 805 Nuclear Safety Capability Assessment (NSCA) Variance From Deterministic Requirements (VFDRs) identified fire areas that neither conformed to Appendix R requirements nor had established, proceduralized and practiced compensatory measures in place. The issues were identified in the DCPP corrective action program and compensatory measures were established in accordance with the DCPP fire protection program requirements.

"Event: 10/3/12 Fire areas containing cables associated with startup transformers 1-2 and 2-2 could result in loss of startup power and also prevent the emergency diesels from performing their Appendix R safe shutdown function.

"Event: 10/8/12 Fire areas containing reactor coolant pump (RCP) breakers could result in loss of RCP seal cooling and prevent the credited local manual trip of the RCPs, contrary to the specified method of performing the Appendix R safe shutdown function.

"Event: 10/8/12 Fire areas containing cables for the ventilation systems of the 480V switchgear, DC panels, and battery chargers could require unproceduralized use of portable fans to maintain adequate cooling of the electrical equipment necessary to perform the Appendix R safe shutdown function.

"Operators established fire watches as compensatory measures as required by the DCPP fire protection program requirements.

"The above late notification of discovery of the unanalyzed conditions has been entered into the DCPP corrective action program.

"NRC Resident Inspector has been notified."
