The following information was received via E-mail:
"On May 31, 2018, the Department [PA DEP Bureau of Radiation Protection] was notified by the licensee that a malfunction of a roll pin on a shutter handle occurred at a temporary jobsite in Eighty Four, Pennsylvania. It is initially reportable per 10 CFR 30.50(b)(2).
"A roll pin, which holds the shutter handle to the shutter shaft on a Berthhold Model LB 8010 in-line density gauge containing 20 milliCuries of cesium-137 became sheared off during an attempt to move the shutter to the open position, rendering the gauge unusable. The gauge is currently being stored at their Punxsutawney, PA location. The shutter is in the closed position and the gauge is out of service awaiting repair from the manufacturer. There was no other damage to the gauge. No overexposures have occurred.
"Radionuclide: Cs-137
Manufacturer: Berthold
Model: LB 8010
Serial Number: 10485
Activity: 20 mCi
"The cause of the event has been attributed to normal wear and tear on the gauge. A reactive inspection is planned by the Department."

NMSS_EVENTS_NOTIFICATION (EMAIL) | | This material event contains a "Category 3" level of radioactive material. | Event Text LOST IODINE-125 SEEDS
On 5/30/2018 a physicist for Christiana Care Home Services discovered that 50 Iodine-125 seeds were missing from the Hot Lab. The licensee began investigating to determine what happened to the seeds. The licensee determined that the seeds had been initially brought into the Hot Lab on 2/6/2018. The licensee believes that on 3/16/2018 an employee from Occupational Safety picked up empty trays from the Hot Lab to recycle them as part of their recycling program and that the Iodine-125 seeds may have been on two of the trays picked up. The trays were taken to a trailer where normal scrap metal is placed and were later picked up by the recycling company.
The licensee believes, but could not confirm that the recycling company picked up the trays along with the seeds which were then taken to universal waste disposal. The licensee interviewed the occupational safety individual and the individual could not confirm that he saw any Iodine-125 seeds in the trays he placed into the recycling box. The licensee has also contacted the recycling company to determine if the boxes can be retrieved, however, the recycling company stated that the box of scrap metal could not be retrieved at this point.
The licensee contacted the Iodine-125 vendor to confirm that the inventory that they have in their possession was correct. The quantity of seeds missing consisted of 50 Iodine-125 seeds with a total activity of 6 millicuries.
THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL
Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging.

NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - FAILURE OF RADIOGRAPHY SOURCE TO RETRACT
The following information was received via E-mail:
"On June 1, 2018, the Agency [Texas Department of State Health Services] was notified by the licensee that a radiography crew was unable to retract a 50 Curie Iridium-192 source into an INC 100 exposure device. The crew was working in a remote area in West Texas when they could not get the source to go past the inlet nipple of the exposure device. After a few attempts, the crew contacted the licensee and an individual authorized to recover sources was sent to the site.
"The licensee did not have specific information on how the source was retracted, but stated it took the individual about 45 minutes to recover the source. The source was returned to the fully shielded position. The exposure device and source were returned to the licensee's storage area and will be sent to the manufacturer for inspection. The licensee stated the exposure device was surveyed and radiation levels were normal.
"The licensee reported that one individual's 0 - 200 millirem self-reading dosimeter did go off scale. The individual's OSL dosimeter has been sent to the licensee's dosimetry processor for reading. The licensee stated it calculated the individual's dose to be 400 millirem based on an interview with the individual. The licensee stated no individual involved received an exposure that exceeded any limit. No member of the general public received an exposure from this event. Additional information will be provided as it is received in accordance with SA-300."

* * * UPDATE FROM ART TUCKER TO GEROND GEORGE ON 7/11/2018 AT 1125 EDT * * *
The following information was received from the State of Texas via email:
"On June 1, 2018, the licensee reported one of its crews were unable to retract a 50 curie iridium - 192 source to the fully shielded position. The licensee's written report received June 29, 2018, stated one of the radiographers had disconnected the guide tube from the exposure device and saw the source was not in the shielded position. The licensee stated the radiographer would have been in contact with the guide tube for 3-5 seconds. The individuals badge was sent for processing and had a reading of 312 millirem DDE. The licensee's initial calculation for the exposure to the individuals hands was 450 millirem. The Agency questioned the dose assessment to the hand. On July 11, 2018, the licensee's radiation safety officer stated they have contacted a service company to perform the dose calculations for the individuals hands. Pictures of the individuals hands taken on July 11, 2018, show no adverse effects from the exposure."

The following report was received from the Ohio Bureau of Environmental Health and Radiation Protection via email:
"The Licensee had a truck with a CPN Model MC1DR gauge in it, stolen at approximately [1330 EDT] on 5/31/18 from a convenience store in southeast Columbus. The gauge contains 10 mCi of Cs-137 and 50 mCi of Am-241 sealed sources. The truck and gauge were recovered by police several hours later. The Licensee got the truck and gauge back about [2100 EDT] that evening. The gauge case had been opened, but the gauge did not appear to be damaged. The Licensee is taking the gauge to Cline Technical Services (a licensed service provider) to have it checked out as a precautionary measure. An ODH [Ohio Department of Health] inspector [will be visiting the] licensee location on Monday, 6/4/18."
Ohio Item Number: OH180004
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 June 12, 2018, at 1500 CDT, a Reactor Coolant System (RCS) Pressure Boundary leak was identified during a Mode 3, hot shutdown walkdown on a High Pressure Injection Line [HPI] to Reactor Coolant Pump (P32C) drain line weld near MU-1066A HPI Line Drain Valve and MU-1066B HPI Line Drain Valve. The 3/4 inch drain line containing drain valves MU-1066A and MU-1066B on the 'C' HPI header (CCA-5 pipe class) has a through-wall defect on the pipe stub or welds between the sockolet and valve MU-1066A. The leak location is in the ASME Class I RCS Pressure Boundary.
"The hot shutdown walkdown was being performed as part of a planned outage to investigate excessive Reactor Building Sump inleakage. Total unidentified RCS leakage prior to the investigation was determined to be at 0.165 gpm. After the initial investigation of the leakage, the following Tech Specs [TS] were determined be applicable: TS 3.4.5 - RCS Loops Mode 3, TS 3.4.13 - RCS Leakage, TS 3.5.2 - ECCS. Unit 1 is currently in Mode 3 and in progress of an RCS cooldown to comply with Tech Spec requirements."
