On 1/23/05, a Radiation Protection Technician released nitrogen into the RAF Countroom as part of an experiment. During the experiment, the atmospheric monitors in the room detected life-threatening levels of nitrogen (oxygen deficient atmosphere). This has been determined to meet the criteria for an Unusual Event per Emergency Classification Level Chart P for a release of toxic or flammable gas on site and portable monitors indicate concentrations at life threatening levels." Management became aware of the unauthorized experiment conducted by the Technician during a management review. There were no personnel injuries as a result of this incident. The licensee will inform both state/local agencies and the NRC Resident Inspector. * * * UPDATE FROM LICENSEE (ROBB) TO NRC (HUFFMAN) AT 1907 EST ON 2/24/05 * * * "On 2/24/05 at approximately 1720 hours, it was discovered that a second incident had occurred prior to the previously reported occurrence (EN#41398) that met the Emergency Plan criteria for an Unusual Event declaration. Based on the investigation of the 1/23/05 incident, the same Radiation Protection Technician had released liquid nitrogen in the Auxiliary Building elevator, as part of the same data collection activity. The release may have been at the levels of 'Immediate Danger to Life and Health' in this separate case. This previous incident occurred on 1/22/05 at approximately 1200 hours." The licensee will inform both state/local agencies and the NRC Resident Inspector. R3DO(Lanksbury), NRR EO (Carpenter), and IRD (Kennedy) notified. | General Information or Other | Event Number: 41429 | Rep Org: TEXAS DEPARTMENT OF HEALTH Licensee: PSI, INC.

The device contains a double encapsulated source of 10mCi of Cs-137 that was last leak tested on 12/09/04. The source rod handle was padlocked and key was removed according to the technician. The shipping/transport case was lost in the Brownsville, TX area where it was being used at a temporary jobsite. "Per company protocol and as discussed during loss notification to TX DSHS, a $500.00 'no-questions-asked' reward for the recovery of the device to be issued to area media outlets." Texas Incident No: I-8213 * * * UPDATE FROM R. JISHA TO J. KNOKE AT 12:41 EST ON 2/23/05 * * * "The gauge was apparently lost off the back of a pick-up truck at a job site in the vicinity of FR511 and EXPWY. 77 an incorporated area northwest of Brownsville proper. Since the gauge was not secured in the case which was secured to the vehicle, it was not lost but presumably the device had bounced off the truck on a rough section of road. Multiple attempts were made to retrace the route but none were successful in recovering the device. The manufacture (Troxler) has been notified." Notified R4DO (D. Powers) and NMSS (S.

In addition, three signs were located in the store (under construction). A forth sign was damaged in the store. The [damaged] sign was not glowing as the other three. This information was supplied by the Tucson Police Department to AZ DPS who advised the Agency. The Tucson Fire Department was also at the site and they indicated they thought the sources were removed between Friday night and Monday morning. The building does not have doors or windows, but is otherwise closed. "Since the facility is under construction, who is the responsible party is a portion of the investigation. The signs have not been reported as transferred into the State. The devices were made by Isolite and contain 11.5 Curies of Tritium each. As much as 103.5 Curies of tritium may be missing in addition to the 11.5 [Curies] in the broken exit sign. Tucson Police report # 0502210205 applies to this event.

There was a preliminary report of a possible fire/smoke smell in the vicinity of the M-G set. However, when an operator reported to the location there was no observed fire. The fire brigade was also dispatched but found no fire or smoke in the M-G set area. The licensee is preparing to place the RPS on its alternate power supply. This will allow the Group 2 isolations and standby gas treatment system actions to be reset. The cause of the M-G set trip is still under investigation. The licensee will be notifying the NRC Resident Inspector as well as state and local authorities. | Power Reactor | Event Number: 41442 | Facility: COLUMBIA GENERATING STATION Region: 4 State: WA Unit: [2] [ ] [ ] RX Type: [2] GE-5 NRC Notified By: RICHARD MEYERS HQ OPS Officer: JOHN KNOKE | Notification Date: 02/25/2005 Notification Time: 04:42 [ET] Event Date: 02/24/2005 Event Time: 18:00 [PST] Last Update Date: 02/25/2005 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(3)(v)(D) - ACCIDENT MITIGATION | Person (Organization): DALE POWERS (R4) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 2 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text POTENTIAL BREACH OF SECONDARY CONTAINMENT DURING SEISMIC EVENT. The licensee provided the following information: "This event notification is being made to report an event that could have prevented fulfillment of the safety function to mitigate the consequences of an accident IAW 10CFR50.72(b)(3)(v)(D). "The potential for creation of an actual hole through Secondary Containment (SC) via the Plant Service Water (TSW) system high point reactor building auto vents (TSW-AV-1A and TSW-AV-1 B) exists if a seismic event occurs and the Seismic Category 2 TSW loop-seal piping outside of Secondary Containment is breached (e.g., because of a pipe break) and has drained. "Neither of the above conditions presently exists. However, a Secondary Containment breach could occur as a result of a single passive failure (i.e., pipe break in the TSW loop-seal piping described above). TSW-AV-1A and TSW-AV-1B are designed to open automatically when neither TSW system pump is operating to break the vacuum condition that would otherwise exist in the piping. When TSW-AV-1A and TSW-AV-1B are open in vacuum breaker mode, the resultant hole size into the TSW system piping would exceed the allowable Secondary Containment cumulative hole size [ of 32 square inches total], if the loop seal were also breached as described above. Due to this condition Secondary Containment was declared INOPERABLE at 1800 PST 2/24/05. As a compensatory measure to prevent exceeding the allowable Secondary Containment cumulative hole size, one of the two TSW reactor building auto vents (TSW-AV-1B) was isolated by closure of a manual valve (TSW-V-55B). This action was completed at 1828 PST 2/24/05 and the Secondary Containment was declared OPERABLE. One TSW auto vent is sufficient to perform the vacuum breaker function." This condition was found by the licensee's System Engineer. The extent of condition and long term corrective action is under review by licensee. Licensee will inform the NRC Resident Inspector. | |
