| Event Text AGREEMENT STATE REPORT - STUCK SHUTTER ON OHMART/VEGA MODEL GAUGE
"On May 2, 2011, the Agency [Texas Department of Health] was notified by the licensee that during routine checks on an Ohmart/Vega nuclear gauge model SHD containing 250 millicuries of Cesium (Cs) 137 (original activity), the shutter was found stuck in the open position. The gauge is mounted on a tank and is located 100 feet above ground and does not create an exposure risk. The gauge is used for level detection. The licensee has lubricated the operating mechanism several times to get the shutter to operate, but it remains stuck. A service provider will be contacted to conduct repairs if needed. The gauge was installed in 1990 time frame and is to be replaced in the future. Addition information will be provided as it is received in accordance with SA-300."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE - STOLEN TROXLER MODEL 3430
"On May 3, 2011, the Agency [Texas Department of Health] was notified by the licensee that a Troxler Model 3430 moisture/density gauge had been stolen from the back of one of their trucks. The gauge was stolen at the intersection of Nalor and North Main in Houston, Texas. The gauge contains a 40 milliCurie Americium (Am) - 241 source, and an eight milliCurie Cesium (Cs) -137 source. The licensee reported that their technician had completed his work and returned to the licensee's facility. When the technician went to the back of the truck to get the gauge, he found the gauge missing, one chain and lock missing, and the other lock had a busted bail. The technician contacted the other licensee's technicians who where at the work site to see if any of them had the gauge. No one did. The technician contacted his manager and reported the missing gauge. The licensee contacted local law enforcement and notified them of the theft. The Agency has sent notification of the theft to the Texas Association of Pawn Brokers. Additional information will be provided as it is received in accordance with Reporting Material Events SA-300."
The serial number of the gauge is 63670. The source numbers are 78-6298 and 77-9880.
Texas Incident: I-8841
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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
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 |

"A planned maintenance evolution at the James A. FitzPatrick (JAF) Nuclear Power Plant will remove the Technical Support Center (TSC) ventilation system from service. The TSC ventilation system will be rendered non-functional during the course of the work activity. The TSC ventilation is expected to be out of service for approximately 9 hours from 0400 to 1300 today.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological or other conditions. If relocation of the TSC becomes necessary, the station Emergency Plant Manager will relocate the TSC staff to an alternate location in accordance with applicable site procedures giving first consideration to the Control Room. TSC facility leads have been made aware of this contingency.
"This notification is being made in accordance with 10CFR50.72 (b)(3)(xiii) due to the potential loss of an emergency response facility (ERF). An update will be provided one the TSC ventilation has been restored to normal operation."
The NRC Resident Inspector has been notified.

As of 1215 EDT on 05/05/11, the planned maintenance activity on the TSC ventilation system is complete. Post work testing is complete and the system has been restored to its fully functional state.
The NRC Resident Inspector has been informed. Notified R1DO (Harold Gray) |

"At 1035 hours CDT on May 5, 2011, the TSC ventilation was secured due to the performance degradation of the air handling unit's fan. The air handling unit is required to maintain a positive pressure in the TSC when the ventilation system is in the emergency mode. At this time, repair activities are being pursued for the fan.
"If an emergency is declared requiring TSC activation, the TSC will be staffed and activated using existing procedures. In the event TSC evacuation is warranted due to radiological conditions, key emergency response organization members would be relocated in accordance with existing procedures.
"This event is reportable per 10 CFR 50.72 (b)(3)(xiii) given the impact on the emergency response facility.
"The NRC Resident Inspector has been notified." |

Operators were making preparations to fill the Containment Spray System riser to support outage activities. At 0204 CDT, when Containment Spray Riser Isolation Valve CS-125A was opened, pressurizer level began to lower. The licensee suspects leak by of a valve in the Shutdown Cooling System. At 0214 CDT, the leak was stopped. Pressurizer level was lowered by 2.6%.
After reviewing the event, the licensee determined that the leak rate was greater than 25 gpm which would have resulted in a declaration of an Unusual Event under EAL CU1. Since the event had concluded, no declaration was made.
The licensee notified the NRC Resident Inspector. | |
