TROXLER GAUGE DAMAGED DURING FIRE

At approximately 1600 hours, a propane tank at a construction site located at 15136 Rutan Lane in Charlotte, NC exploded. The resulting fire fully engulfed a pickup truck containing a Troxler moisture density gauge. NC Radiation Protection was informed at 1703 hours by NC Emergency Management of the incident and has dispatched an Inspector to the scene to assist Hazmat. The initial radiation readings provided by Hazmat show preliminary readings of .3 mr/hr (not sure whether this is contact or near the gauge).

* * * UPDATE PROVIDED BY LEE COX TO JEFF ROTTON AT 2205 ON 04/03/07 * * *

The North Carolina Radiation Protection Inspector is onsite at the scene of the explosion. The truck was damaged beyond repair and the Inspector was able to locate both gauge sources with survey instruments. The Troxler gauge is a model 3440 with a 40 millicurie Am-241:Be source and a 8 millicurie Cs-137 source. Both sources were located in the bed of the truck. The Am-241 source was outside the gauge housing and the Cs-137 source was still attached to the source handle/rod. Neither source was breached. The Inspector was able to use various retrieval instruments to pickup both sources and place them into a temporary transportation package created on the scene and use available material for shielding and packaging to secure the sources. The temporary transportation package was secured in the bed of a truck with a cab over the truck bed. Radiation readings in the cab of the truck and on the sides of the truck bed were background. Radiation readings at a distance of 1 meter from the package was < 2 mR/hr. The radiation reading on contact was 15 mR/hr. The truck with the damaged Troxler gauge was escorted by the NC Radiation Protection Inspector to the South Carolina licensee's site located at 3575 Center Circle, Fort Mill, SC 29715, South Carolina License # -777. The gauge manufacturer, Troxler, was contacted and will be sending a DOT approved transportation container so that the licensee can return the damaged gauge to the manufacturer. NRC Region 1 (Kinneman) and the State of South Carolina were notified by the North Carolina Radiation Protection Office.

SEVERAL CHECK SOURCES STOLEN FROM A UTILITY TRAILER

The following information was received via e-mail from the State of New Mexico:

"[NM Radiation Protection Control Bureau] received notification at approximately 2:30 p.m. that seven (7) sets of button check sources licensed to the NM Radiation Control Bureau were being stored in a NM Department of Health utility trailer that was stolen in Albuquerque, NM over the weekend. These sources are used as check sources for survey meters (also stolen) during training sessions for emergency response personnel at facilities along the WIPP routes in NM. This incident is being investigated by NM State Police and the Albuquerque Police Department. Personnel from the Department of Homeland Security, the NM Department of Health, and the WIPP Emergency Response Program of the NM Radiation Control Bureau are also involved in the investigation and will provide a press release. The following sources were reported missing:

7-10 nanoCurie Pu-239

7-10 nanoCurie Sr-90 (exempt)

7-1 microCurie Cs-137 (exempt)

"More details will be provided as they become available."

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source.

AGREEMENT STATE REPORT - STOLEN PALLADIUM SEEDS

The State of Louisiana received a report from a licensee representative that 101 Palladium 103 seeds, with a total activity of 132 millicuries, were stolen. The seeds were stolen from a truck at 2235 Highway 178 in Sunset, LA. The seeds had been accepted by the licensee from the shipper and were going to transported to the hospital by the licensee representative.

The licensee notified the Louisiana State Police and local law enforcement and is following up on the incident.

* * * UPDATE ON 4/4/07 AT 1630 EDT FROM PATE TO SNYDER * * *

The following information was received via e-mail from the State of Louisiana:

At the time of the theft the truck was parked at the residence of the licensee's Radiation Safety Officer (RSO). The RSO contacted the St. Landry Parish Sheriff and the Louisiana State Police. The seeds were in the vehicle on the rear seat inside a red, padlocked, metal tool chest labeled as radioactive material. The approximate dimensions of the tool chest are 1.5 to 2 feet long and 8 to 10 inches wide. The seeds were contained in seven plastic sleeves that were attached to the inside of one stainless steel container that was inside another stainless steel container.

Louisiana Department of Environmental Quality has dispatched three inspectors out to search the area where the sources were stolen with instrumentation. "If the Palladium sources were piled together outside of their shielded containers, this would result in a radiation exposure roughly 16.6 [millirem/hour] at one foot.

"[The RSO] has stated that the facility will be notifying the public by television and newspapers."

Notified R4DO (C. Cain) and FSME EO (D. Rathbun).

AGREEMENT STATE REPORT - FIXED LEVEL GAUGE SOURCE FAILURE TO RETRACT

The following information was reported to the NRC via facsimile:

The Utah Division of Radiation Control was initially notified by telephone on March 3, 2007 at about 10:20 am MST by the licensee's consultant that a source of a fixed level gauge at the Hunter Power Plant near Castle Dale, Utah failed to retract into the safe shielded position. The gauge is a Texas Nuclear Model 5197, Serial Number 1305 level gauge containing 100 millicuries of Cs-137. The licensee contacted their service consultant who discovered that the handle on the gauge was bent. The consultant indicated that it appeared that someone had attempted to turn the handle on the gauge without pulling the button. This act had apparently bent the handle. When the licensee had attempted to close the device properly, the bent handle did not allow the drive cable to align properly with the source to retract it.

This incident is being tracked by the State as Utah Report ID No. UT-07-0002.

MAIN GENERATOR TRANSFORMER EXPLOSION - NO IMPACT ON PLANT SAFETY RELATED SYSTEMS

At 1143 on 4/6/07 the licensee declared an Unusual Event due to a main transformer explosion in the protected area. The event was declared in accordance with EAL 8.2.2. Unit 3 automatically tripped due to a load reject at the main generator. The Unit is currently stable at normal operating temperature and pressure. Decay heat is being removed via the steam dumps to the main condenser. All emergency diesel generators are available if needed but safety buses are currently supplied with offsite power.

At the transformer site the deluge system actuated and the fire brigade responded. The fire was out at the time of the report

The licensee informed the NRC Resident Inspector.

* * * UPDATE AT 1232 ON 4/6/07 FROM LAUGHLIN TO HUFFMAN * * *

The offsite local fire department was called by the licensee but their support was not needed and they were released.

* * * UPDATE AT 1259 ON 4/6/07 FROM LAUGHLIN TO HUFFMAN * * *

The licensee exited Unusual Event at 1247 based on the fact that the fire was confirmed to be extinguished, there was no damage to safety equipment and the plant was in a safe and stable condition.

* * * UPDATE AT 1440 ON 4/6/07 FROM PRUSSMAN TO KNOKE * * *

"On April 6 at 1143 hours, an unusual event was declared based on Emergency Action Level 8.2.2, an explosion in the 'B' phase of the 31 main transformer. This is a one hour reportable event to the NRC made at 1159 hours. This is an update of EN 43285. The NUE was terminated at 1247 hours.

"The State and County were also notified of the unusual event. A press release was made. Although no one was injured as a result of this event, a four hour report is being made since this is related to on-site personnel safety. The main generator tripped and this resulted in a consequential reactor trip. The Reactor Protection System shut down the reactor at 1109 hours, a four hour report. The plant operated as designed and the Auxiliary Feedwater System actuated, an eight hour report. The fire was reported to the Control Room at 1111 hours. The fire was put out in less than 15 minutes.

"The event is currently under investigation."

The header information in this event was revised as a result of this update to indicate 'Offsite Notification.'

INITIATION OF INVALID PRIMARY CONTAINMENT ISOLATION SIGNALS

"This is not an L.E.R. The report is being made to the NRC under 10 CFR 50.73(a)(2)(iv)(A), and the 60 day telephone notification option under 10 CFR 50.73(a)(1). The event included invalid 'general containment isolation signals affecting containment isolation valves in more than one system' as discussed in 10 CFR 50.73(a)(2)(iv)(B).

"(a) 'The specific train(s) and systems that were actuated.'

"On January 11, 2007 at 12:11 hours, Unit 2 received invalid Primary Containment Isolation signals to both Group 5 (RHR Shutdown Cooling System Isolation valves) and Group 10 (Reactor Core Isolation System Isolation valves) during instrumentation surveillance testing. While performing testing of the Division I Group 5 and Group 10 isolation functions of the RHR ambient temperature instrumentation, Technicians omitted a procedural step, resulting in the invalid signal actuations.

"(b) 'Whether each train actuation was complete or partial.'

"The event resulted in closure of the RCIC steam supply header outboard containment isolation valve. The Division 1 RHR Shutdown Cooling System isolation valves were already closed at the time of the isolation signal.

"(c) 'Whether or not the system started and functioned as designed,'

"The Primary Containment Isolation instrumentation logic and associated valve closure function (for RCIC) actuated as designed. The reporting of this event exceeds the 60 day notification requirement as a result of initially not fully understanding the impact of the invalid signal actuation. This condition has been entered into the Corrective Action Program."

The licensee notified the NRC Resident Inspector.

FIRE IN THE REACTOR PROTECTION SYSTEM DIVISION 2 EQUIPMENT ROOM

"On April 7, 2007 at 1330 Pacific Daylight Time (PDT) Columbia Generating Station (CGS) experienced an electrical fire in the Reactor Protection System (RPS) Division 2 equipment room. Currently, reactor level is stable and being controlled with the feedwater system. Reactor pressure is stable and being controlled with the turbine bypass valves in automatic. All safety systems are functional and there were no ECCS system actuations. At this time the plant is stable and the source of the fire was an electrical transformer which feeds the alternate electrical power supply to a Division 2 inverter isolation logic."

Plant operation was not impacted and the plant continues to operate at about 95% power. The first responder on-site extinguished the fire with a hand held fire extinguisher at about 1339 local time. The licensee has informed the NRC Resident Inspector.

* * * UPDATE AT 1758 EDT ON 4/7/07 FROM F. SCHILL TO P. SNYDER * * *

The Emergency Action Level (EAL) entry condition for the Alert was a 'report by plant personnel of visible damage to equipment contained in a safe shutdown building' EAL 9.2.A.1. The equipment damaged was the backup power supply to the inverter. CGS has a fire watch established in the area to watch for reflash.

* * * UPDATE AT 2024 EDT ON 4/7/07 FROM F. SCHILL TO P. SNYDER * * *

The Alert condition was terminated at 1721 PDT based on the fact that no reflash was seen by the fire watch, the extent of the equipment damage is understood and the area is now cool.
