"ENS Event Number 53014, made on 10/13/2017 is being retracted.
"NRC notification 53014 was made to ensure that the Eight-Hour Non-Emergency reporting requirements of 10 CFR 50.72 were met when a leak on a threaded union, along with piping vibration, was identified on U1 HPCls Lube Oil Cooler & Gland Seal Condenser Pressure Control Valve sensing line (1-PCV-073-0043).
"A Past Operability Evaluation [POE] was performed under CR# 1347736. The evaluation concluded that HPCI was degraded, but met the threshold for TS operability. Specifically the vibrations shown were evaluated and deemed to not impact pipe integrity. These vibrations were also evaluated for seismic events. Based on this the POE concluded that HPCI was capable of performing its intended safety function for its designed mission time.
"As such, the circumstances discussed in the report did not result in any condition that at the time of discovery could have prevented the fulfillment of the safety function of structures of system that are needed to remove residual heat. Thus, there was no impact on nuclear safety. Therefore, this event is not reportable under 10 CFR 50.72(b)(3)(v)(B).

"A Past Operability Evaluation [POE] was performed under CR# 1406178. The evaluation concluded that HPCI was degraded, but met the threshold for TS operability. Specifically the POE states that if the leak was left unaddressed for 8 hours (mission time) with HPCI in operation, the additional volume of water that would accumulate on the HPCI room floor would be approximately 5520 gallons which would be within the capacity of the floor drain pumps and spill over into Torus area to prevent water level from reaching a value which would preclude operation of HPCI critical components. Additionally the leak was upstream of the system flow controller, so the leakage rate of 11.5 gpm would not affect the ability of the HPCI pump to provide rated flow of 5000gpm.
"As such, the circumstances discussed in the report did not result in any condition that at the time of discovery could have prevented the fulfillment of the safety function of structures of system that are needed to remove residual heat.

PATRICIA MILLIGAN (INES) | Event Text AGREEMENT STATE REPORT - PATIENT SKIN CONTAMINATED WITH FLOURINE-18
The following summary was received from the North Dakota Department of Health via telephone:
On April 4, 2018 the licensee reported that a patient undergoing a PET (Positron Emission Tomography) scan was squirted with 15 millicuries of FDG (Fluorodeoxyglucose) - Flourine-18, by the technologist administering the dose. A peak skin dose of 2 Gray was calculated by the licensee Radiation Safety Officer.
The North Dakota Department of Health is awaiting additional information from the licensee regarding the event.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
* * * UPDATE ON 06/01/2018 AT 09:17 FROM BROOKE OLSON TO THOMAS KENDZIA * * *
"On April 4, 2018 a patient was imaged with ~15 millicuries of FDG. At the time of the injection, it is now believed that ~15 millicuries dose was inadvertently delivered on the patient's shirt. Since the first dose wasn't administered as intended, a second ~15 millicuries dose was administered into the patient. Per protocol the patient rested for an hour and was imaged. The patient was released from the scan room and was discharged and went to the cafeteria. The [study] physician reviewed the images and found them non-diagnostic due to external contamination. The [study] physician ordered that the images be repeated. The patient was located in the cafeteria and returned to Nuclear Medicine and his shirt was removed. Patient was reimaged approximately an hour after the start of the first scan (approximately 2 hours after the shirt was contaminated) and the second set of images were deemed to be diagnostic.
"On May 15, 2018 the RSO [Radiation Safety Officer] learned of the event and began an investigation. The skin dose is estimated to be approximately 2.8 Gy to 100 cm2 of tissue. This exposed tissue was on the patient's torso. The uncertainty in the skin dose calculation is great. Due to the complexity of the calculation, the skin dose was estimated on May 31, 2018.
"The study physician is aware of the incident and will notify the referring physician. The patient is unlikely to have noticeable negative effects from the incident, however if the patient did have a tissue reaction, it would have been mild and transient. The patient has not yet been notified of any of the findings since the RSO was made aware, however the patient was aware that he was spilled on and that his shirt was kept for decay. Notice will be sent to the patient offering the ability to obtain a written description of the event.
"Continued investigation is in process and will start with a review of reporting requirements and event management related to radioactive spills."
Notified the R4DO (Farnholtz), INES (Milligan), and the NMSS Events Notification email group.

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

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.

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."

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."

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.
