| Event Text AGREEMENT STATE REPORT - NUCLEAR GAUGE SHUTTER FOUND STUCK
The following information was received from the State of Texas via email:
"On July 8, 2015, the Agency was notified by the licensee's radiation safety officer (RSO) of a stuck shutter on an Ohmart Vega SH-F2 nuclear gauge containing a 500 millicurie Cesium - 137 source. The stuck shutter was found during a routine six month inspection. The RSO determined the source shutter would not operate due to internal corrosion seizing it in the open position. The RSO verified the radiation levels in the area of the gauge had not changed. The RSO stated the source normally operates in the open position and there are no safety issues. The RSO stated he had contacted a service provider to make repairs to the gauge. The RSO stated a replacement internal shutter mechanism equipped with a gasket will also be ordered for installation to prevent future water intrusion and corrosion. The gauge does not pose an exposure risk to the licensee's workers or to members of the general public. Additional information will be provided as it is received in accordance with SA-300."

The following was received form the State of Louisiana via fax:
"LA DEQ [Louisiana Department of Environmental Quality] Radiation Section was notified on Thursday July 2, 2015, 2155 [CDT], by a representative from Toulong-Wong Engineers, Inc., of the theft of a Troxler MD [Moisture Density] Portable Gauge. The gauge and transport case was stolen from the bed of a Toyota Tundra pickup [Dark Gray newer Toyota Tundra pickup] parked in the front of the operator's residence. It was secured to the truck by two end cables, the case was locked and the gauge itself was locked. The end cables were cut and the transport container and gauge were stolen. The Gauge was a Troxler, Model 3430, s/n 25042, loaded with Cs-137 9 mCi, s/n 75-7211 and Am-241 44 mCi, s/n 47-21246.
"The LA [DEQ] has inspectors involved and will continue to keep NRC informed of the status of our investigation.
"LA Department of Environmental Quality, Radiation Section. The call came into the 24 hour emergency hotline. The Baton Rouge City Police [Department] was notified and a theft report was filed.
"[A] press release has been issued, with contact information, photos, and a reward for recovery."
Louisiana Incident # LA 150012
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.

| Event Text TROXLER MOISTURE DENSITY GAUGE DAMAGED BY BULLDOZER
At a temporary construction site in Yale, MI, a Troxler Model 3440, s/n 26515, was run over by a bulldozer. The gauge user was injured and taken to a local hospital. TTL Associates, a materials testing lab located in Plymouth, MI, is responding to the scene to recover the damaged gauge and perform radiation surveys. Local HAZMAT was also contacted. The gauge was in a wheel barrow and not in use at the time it was struck. The licensee is contacting Troxler for instructions to return the gauge.
The Troxler Model 3440 contains two sources; Cs-137 and Am:Be-241 of 8 mCi and 40 mCi, respectively [typical values].
* * * UPDATE AT 1731 EDT ON 07/09/15 FROM JEFF ELLIOTT TO DANIEL MILLS * * *
The gauge was recovered from the construction site with the source still in the locked and stored position and is enroute to TTL Associates for evaluation prior to return to Troxler Labs. A survey of the affected area found no contamination. |

| Event Text SEALED I-125 SOURCE DAMAGED DURING PATHOLOGY EXAMINATION
A breast implant of an I-125 seed had been performed followed by a lumpectomy. The lump with the implanted seed was sent to the pathology lab for analysis. During the analysis, the Pathology assistant cut through the I-125 seed. No contamination was noted on the counter top and a thyroid scan of the Pathology assistant was negative.
"1) The source was placed in the leaded container which would not allow any I-125 to escape and release any radioactivity any longer.
"2) There was no radioactive material left on the countertop which was further verified by a wipe test.
"3) A thyroid bioassay was performed on the Pathology assistant working on the specimen and the results were negative.
"4) On 7/9/15 a wipe test of the source revealed that the source integrity was compromised indicated by elevated counts on the wipe compared to the background (4900 dpm vs 120, indicating an activity of approximately 1.5 micro Curie). This indicates that surface of the solid source is contaminated.
"5) [The licensee] will also contact the vendor to find out if the source can be returned to them (since the source is in a sealed shielded container)." |

"On July 13, 2015, planned activities will be performed to upgrade the Vogtle Electric Generating Plant Meteorological Towers and its communication equipment. The emergency response data system will be affected. The work will be completed within approximately 5 days. This activity requires the meteorological tower to be out of service greater than 72 hours rendering equipment used for emergency assessment non-functional.
"The TSC and EOF remain functional during the outage. Compensatory measures exist within emergency plan implementing procedures to obtain meteorological tower data via Savannah River Site and with the National Weather Service. Meteorological information will be relayed via the emergency notification system to the NRC Operations Center.
"This event is reportable per 10 CFR 50.72(b)(3)(xiii) for 'any event that results in a major loss of emergency assessment capability.' The Emergency Response Organization has been notified of the upgrade and necessary compensatory actions.
"The NRC Resident Inspector has been notified."

"At 0004 [CDT] on Wednesday, July 15, 2015, the Dresden Nuclear Power Station (DNPS) Technical Support Center (TSC) emergency ventilation system will be removed from service for planned maintenance activities. During the maintenance, the TSC Ventilation will be shut down. The TSC air filtration fan and dampers will be non-functional, rendering the TSC HVAC accident mode non-functional. This maintenance is scheduled to minimize out of service time. The planned TSC ventilation outage is scheduled to be completed in approximately 24 hours.
"Contingency plans are in place so that if an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing Emergency Planning (EP) procedures and checklists. If radiological or environmental conditions require TSC facility evacuation during ventilation system restoration; the Station Emergency Director will relocate the TSC staff in accordance with station procedures."

"At 1214 CDT on 7/18/2015, during normal surveillance testing of Z sump, Z2 sump pump run time was found to exceed its upper Augmented IST limit, rendering it non-functional. Operators continued with the surveillance, opening the power supply breaker to Z1 sump pump, rendering it non-functional also. When this was identified, station personnel backed out of testing and restored power to Z1 sump pump. Z sump functions to limit condensation buildup in the common Standby Gas Treatment System (SGT) discharge line to support SGT operability. One sump pump is required to be functional to support SGT operability. With both Z sump pumps non-functional, operability of both trains of SGT is not assured. Loss of both trains of SGT constitutes a loss of safety function for control of rad release and accident mitigation per 10 CFR 50.72(b)(3)(v) functions (C) and (D).
"The breaker for Z1 sump pump was reclosed at 1225 CDT, restoring functionality to Z1 sump pump and operability to both trains of SGT. Both Z sump pumps were considered non-functional and unable to support SGT operability for a period of 11 minutes."
The licensee notified the NRC Resident Inspector. | |
