AGREEMENT STATE REPORT - STUCK OPEN SHUTTER

The following information was received from the State of Texas by email:

"On July 7, 2015, the Agency [Texas Department of State Health Services-Radiation Branch] was notified by the licensee's radiation safety officer (RSO) that the shutter on a Ronan GS-400 level gauge containing a 50 millicurie cesium - 137 source was stuck in the open position. The stuck shutter was discovered during the start up of a system component. Open is the normal position for the shutter. The gauge does not possess an exposure risk to any individuals. The manufacturer has been contacted and will replace the gauge. Additional information on this event will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

The following information was received from the State of Mississippi by email:

"Location of Incident: Brandon, Mississippi, I-20 exit ramp 56 construction.

"Description of Incident: July 3, 2015 at approximately [1630 CDT], a Humboldt Model 5001 portable nuclear moisture density gauge, Serial Number 3339, was run over by a heavy equipment truck while on a jobsite. The gauge was severely damaged, but the sources remained intact and in shielded position. DRH [Mississippi Division of Radiological Health] was notified and provided with a survey measurement of 8mR/hr at the surface of the damaged gauge. The RSO was able to safely load the fragmented gauge back into its approved transport case and return it to the MDOT [Mississippi Department of Transportation] storage facility. DRH personnel visited the MDOT storage facility and observed an 8mR/hr surface survey reading with an NDS ND-2000 survey meter, serial number 24562, calibration date 7-1-2015. Leak test wipes were taken from both sources and sent for analysis by the licensee. The measured activity was well below the regulatory upper limit of .005 microcuries. Wipe analysis was received 7-7-2015. Gauge is being returned to the manufacturer for disposal."

Radioisotopes: Cs-137(11 mCi); Am-241/Be(44 mCi). Radiation measurements taken by the Mississippi Division of Radiological Health: 8 mR/hr at surface; Less than 1 mR/hr at 1 meter.

AGREEMENT STATE - TWO GAUGE SOURCES COULD NOT BE FULLY RETRACTED

The following report was received from the State of Texas via e-mail:

"On July 8, 2015 the Agency [Texas Department of State Health] was notified by the licensee's radiation safety officer that while performing routine test of gauge shutters, they found two gauges where the source could not be fully retracted. Both gauges are Ohmart Vega model SHLMBR-4 gauges containing a 5,000 millicurie cesium-137 source. The gauges are mounted on the side of poly resin tanks. The sources were left in the normal operating, unshielded position. The sources do not pose any additional risk of exposure to the workers or members of the general public. The RSO stated they have not decided how they were going to resolve the problem yet, but will notify the Agency [Texas Department of State Health] once a decision has been made. Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT- LOST MOISTURE/DENSITY GAUGE

The following report was received from the State of California via e-mail:

"On 6/18/15 an RHB [Radiologic Health Branch] inspector discovered one the licensee's gauge cases was empty and the licensee stated they did not know where the gauge was and would do an investigation. The licensee stated they were not able to determine where the gauge was (Troxler, 3441B, #5803 with 8 mCi Cs-137 and 40 mCi Am-241:Be). The last time the gauge was seen was when it was brought to Maurer Technical Services (the CPN representative) for repair on July 23, 2014. The licensee was going to review additional paperwork to see if he could figure out what happened to the gauge, but at this point he has not gotten back to us [RHB] with any additional information. Maurer Technical Services has done a complete search of their facility and said they do not have the gauge. Maurer Technical [Services] does not have a record of which individual picked up the gauge from their facility. The licensee states they do not remember who picked up the gauge and could not find any paperwork to show gauge #5803 had been used after July 23, 2014. The licensee states there had been no break ins at their facility nor had the locked storage cabinet been tampered with. The Department [California Department of Environmental Health] also interviewed all of the current employees and no one can remember who last used the gauge or picked up the gauge from the repair facility. The Department contacted several of the major companies that perform leak test analysis and this gauge had not been leak tested since prior to July 23, 2014. The Department also researched whether the gauge (serial #5803) was listed in the NMED system as having been 'found', but it was not found in any of the reports. The gauge remains missing."

5010 Number: 070615

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.

TECHNICAL SUPPORT CENTER OUT OF SERVICE DUE TO PLANNED MAINTENANCE

"At 0004 [CST] 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."

"The NRC Resident Inspector has been notified."

INADEQUATE WELDS AFFECTING STRUCTURAL CAPACITY OF EMBED PLATES

MOX [Mixed Oxide] Services has determined that the fillet welds connecting the ledger angle to the embed plate did not comply with the minimum size required by AWS D1.1-98 and the design requirements.

The embed plates containing defects were supplied to MOX Services as a basic component by Specialty Maintenance and Construction, Inc. (SMCI) Division of MetalTek International.

The undersize fillet welds connecting the ledger angle to the embed plates were determined to be inadequate. Inadequate welds would adversely affect the load bearing and structural capacity of these components.

CB&I Part 21 interim report, dated January 20, 2015, indicates that Vogtle Units 3 and 4 have been supplied with basic components by SMCI.

These weld defects related to the SMCI embed plates were initially identified by nonconformance report on February 24, 2015.

LOSS OF EMERGENCY ASSESSMENT CAPABILITY DUE TO METEOROLOGICAL TOWER SOFTWARE FAILURE

"This notification is being made due to a loss of emergency assessment capability in accordance with 10CFR 50.72(b)(3)(xiii). At 2332 [CDT], on 07/15/2015, the meteorological tower computer system software failed which resulted in a loss of meteorological data to the plant. Proceduralized compensatory measures for dose assessment include use of National Weather Service followed by historically determined default values. Information Technology personnel reported to the plant and successfully reset the software. Meteorological data to the plant was restored at 0216 [CDT] on 07/16/2015.

"The NRC Resident Inspector has been notified."
