| Event Text DENSITY GAUGE SHUTTER STUCK OPEN
"The gauge is a Kay-Ray Model 7063P, serial number 8289 with a nominal source of 1 Curie of Cesium 137. The gauge is used for lime slurry density measurements in the Unit 1 Scrubber.
"The malfunctioning shutter was discovered on June 6, 2015 during semiannual shutter checks as required by the license. The checks were completed today, and [the Radiation Safety Officer (RSO)] became aware of the issue as [the RSO] reviewed the documentation. Independent verification of the malfunction was made, it was found to not close. The cause of the malfunction is not known at this time.
"The gauge is located approximately sixteen feet above the ground level and presents no unusual risk to plant personnel. No maintenance activities will be conducted on the pipe or elbow the gauge is attached to until the shutter has been repaired. All plant personnel have been notified of the issue and the requisite restriction.
"[The RSO] contacted a properly licensed contractor to arrange for the repair to the shutter."
This gauge is normally open during plant operation. |

| Event Text AGREEMENT STATE REPORT - WELL LOGGING TRITIUM SOURCE BROKEN OPEN DURING MAINTENANCE
The following report was received from the State of Texas via e-mail:
"On June 10, 2015 the licensee contacted the Agency [Texas Department of State Health Services] reporting that an Agency inspector was at the site inspecting the facility. The inspector informed the licensee that a reportable event occurred and was not reported as required. The licensee was making notification that on March 5, 2015, during repair of a pulsed neutron generator tool, the work counter, internal casing and housing of the tool had contamination from a sealed tritium tube. The tube was manufactured by Thermo Fisher, ID 163-D101-S, on April 19, 2013 at an activity rating of 3 curies. The licensee explained that during the check on the tool, readings were seen on the meter. The area was checked and the contamination found and cleared from the tool and counter. The area was tested with wipes and counted. The highest count was 680 cps [counts per second]. The area was wiped clean and the clean up material is in a sealed drum awaiting disposal. The amount of contamination was calculated and the licensee explained he read through the regulations and determined the level of exposure was not reportable. The calculated dose was not provided. No badges were sent to the processor for reading. The tool itself was salvaged and reworked into a new usable tool with a new serial number. A detailed description of the event was requested from the licensee. Investigation into this case is ongoing. Update will be made in accordance with SA300 guidelines."

The following retraction was received from the Texas Department of State Health Services via email:
"More complete information was obtained from the licensee. The pulse neutron generator tool was damaged and the tritium tube was leaking material, contaminating the internal tool and the countertop during repair process. The employee working on the tool noticed increased readings on his survey instrument and immediately checked the tritium tube to find the contamination. The material was confined to the tool and countertop. The tube activity is listed as 3 curies. The employee notified his radiation safety officer of the damaged tool and a dose rate was calculated. The RSO had calculated 40,800 CPM = 680 CPS (background was 120 CPS), 680 CPS x .20 [microSv]/hour (calibration factor) = 136 [microSv]/hour, 136 [microSv]/hour = 0.0136 REM / hour for the dose. The release did not exceed regulatory limits and was not in an operable condition when being repaired. The contaminated area did not require restricted access and the quantity of material did not meet the annual limits on intake exposure. The radioactivity detected in the tool was remediated immediately and contaminated waste [was placed in a] drum for disposal. No aspect of the event met any reporting criteria. It has been determined this was not a reportable event."

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text CD-109 SOURCE IMPROPERLY SENT FOR DISPOSAL
The Alabama Air National Guard (Montgomery, AL) had a thermal night time analyzer with a 40 mCi, Cd-109 source. The source was last inventoried on 1/30/2015. On 4/28/2015, the analyzer was transferred to the disposal facility at the Defense Logistics Agency (DLA) at Robins Air Force Base in Georgia. The Army does not send radioactive sources to this DLA for disposal. The Army has verified receipt of the source at the DLA and is currently trying to determine if the source is still there or has been destroyed.
Source: XLP-303 with serial number 18540
* * * UPDATE AT 0840 EDT ON 6/12/2015 FROM MARCOS VICENTE TO DONG PARK * * *
The following report was received from the licensee via e-mail:
"[The following is] updated information concerning the improper transfer of the Thermo Niton Analyzer by the Alabama Army National Guard to Defense Logistics Agency (DLA) Disposition Services. We were successful in contacting the manufacturer and got information concerning the assay date of the Cd-109 source. Their records indicate an assay date of 15 April 2008. The analyzer was sent to DLA on 28 April 2015. According to our calculations, this drops the activity from 40 mCi to approximately 0.86 mCi from when it was shipped out to DLA. We are still working with DLA Disposition Services to track the location of the analyzer."
Notified the R1DO (Dwyer) and NMSS Events Notification (via e-mail).
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.

"On 6/16/2015, planned preventive maintenance activities [will be] performed on the Braidwood Generating Station Technical Support Center (TSC), Ventilation System. The work will be completed within approximately 48 hours. This activity includes preventative maintenance that requires the TSC ventilation system to be out of service which will render the TSC ventilation system non-functional.
"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 or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff as necessary.
"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 planned maintenance will not be able to restore the TSC condensing unit or ventilation system to service within the facility activation time specified in the emergency plan (1 hour) in the event of an accident. The Emergency Response Organization team has been notified of the maintenance and the possible need to relocate during an emergency.
"The licensee has notified the NRC Resident Inspector."
