The following was received from the state of Pennsylvania via email:
"Notifications: On November 14, 2018, the licensee informed the Department [Pennsylvania Department of Environmental Protection] of a failed shutter. It is reportable per 10 CFR 30.50(b)(2).
"Event Description: The licensee reported that on October 18, 2018, a IRMS Model TG-2 gauge, serial number 00MO397-15, containing 3000 milliCuries of americium 241 did not properly perform following scheduled maintenance. Specifically, the shutter failed to open completely and then would not open at all. The gauge was taken out of service and a service provider was contacted, responded and corrected the problem. The licensee has since contacted the same service provider and, on November 2, 2018, transferred the device for proper disposal. Licensee and service provider survey results indicated no abnormal amounts of radiation in the area before, during or after the event or removal of the device. There were no overexposures related to this event.
"Cause of the Event: Equipment failure.
"Actions: The Department will perform a reactive inspection. More information will be provided upon receipt."

PATRICIA MILLIGAN (INES) | Event Text AGREEMENT STATE REPORT - RADIATION WORKER RECEIVES HIGH DOSIMETRY READING
The following report was received from the Arkansas Department of Health via email:
"The RSO reported at 1100 [CST], on November 14, 2018, that the dosimetry provider had reported to the licensee one radiation worker badge had received a possible exposure of 9,000 mR for the month of October. The dosimetry provider has stated the exposure was a dynamic exposure with atypical exposure to the badge.
"The licensee began to investigate the cause of the high reading. The worker had worked with other employees and had not worked independently during the month. Other workers had routine exposures for the month.
"The licensee requires workers to wear SRD's [Self Reading Dosimeter] while working in the restricted area. The worker's cumulative reading for the time period was 200 mR. The worker's ring badge had routine exposure readings.
"During investigation by the licensee, there was no recollection of the badge being separated from the worker during the month. During off hours, all dosimetry is stored with the worker's lab coats outside the restricted area.
"The licensee develops PET [Positron Emission Tomography] radionuclides for radiopharmaceutical research and development.
"Since the time period of the exposure cannot be determined, the Arkansas Program is reporting this event under RH-1502.b. of the Arkansas Regulations equivalent to 10 CFR 20.2202(b)(1) of the NRC Regulations.
"The licensee and the State continue to investigate.
"The State of Arkansas will update when additional information is known.
"Arkansas event number AR-2018-006."
* * * UPDATE ON 12/14/18 AT 1535 EST FROM STEVE MACK TO BETHANY CECERE * * *
The following update was received from the Arkansas Department of Health (Department) via email:
"The licensee provided a written report dated November 15, 2018, outlining the investigation performed to verify the overexposure reported.
"This report restated the requirements of additional dosimetry worn by the worker with no significant indication exposure above routine doses. The report also indicated that at no time during the month was contamination detected when conducting personnel surveys leaving the restricted area. The licensee continues to believe that the dose was only received by the badge and not to the whole body of the radiation worker.
"The licensee submitted its own dose estimate on December 3, 2018, in which the licensee calculated a possible contamination event of the badge that would provide the dose yet exclude dose to other measuring devices and could evade detection when exiting the restricted area.
"The Department has taken this dose estimate into consideration and is requesting that the October, 2018 dose for the radiation worker be reduced to 250 mrem.
"The Department considers this event closed."

The following report was received via e-mail:
"On Wednesday, November 14, [the University of Miami Radiation Safety Officer (RSO)] received an Occupational Exposure Report from Mirion Technologies indicating that for wear dates July 1 through July 31, 2018, x-ray technologist [redacted] received the following doses: Deep: 8328 mR, Eye: 8328 mR, and Shallow: 8328 mR.
"Upon interviewing Mr. [redacted], in the presence of his supervisor, Mr. [redacted] indicated that he had a therapeutic Nuclear Medicine procedure for hyperthyroidism during the month of July in one of our facilities. Upon review of his medical records it was confirmed that Mr. [redacted] received 24 microCuries of iodine-131 for an uptake scan on July 10, 2018, and a therapeutic dose of 28.9 mCi of iodine-131 on July 17, 2018. It was noted that Mr. [redacted] wears his dosimeter high on the collar of his scrubs, very close to the area overlying his thyroid and continued to wear it throughout the period in question. Based on this information it is [the RSO's] professional judgement that this dose does not constitute an Occupational Dose but is rather a medical dose, and he will be requesting that his dosimetry provider remove it from Mr. [redacted] Occupational [dose]."

On 11/16/2018, a Troxler gauge was declared lost by the EPA while in transit from Ada, OK to the Troxler Corporation in Research Triangle Park, NC. The Troxler gauge departed from the EPA Office of Research and Development to the Troxler corporation for disposal on 11/8/2018. On 11/16/2018, the EPA Radiation Safety Officer contacted Troxler and determined that they had not yet received the gauge. The transportation company was then contacted and the transportation company records indicated that the gauge was still in transit to Memphis, TN, but could not be located. The EPA is still investigating to determine the location of the gauge. The gauge is a Troxler Model 4302, Serial Number 382, containing 10 milliCuries of Am-241/Be.
* * * RETRACTION ON 11/21/18 AT 0959 EST FROM CHERRI ADAIR TO BETHANY CECERE * * *
The intact gauge was located in Richmond, VA. The transportation company plans to deliver the gauge to Troxler, as originally intended.

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.

The following information was received via E-mail:
"On November 16, 2018, the Agency [Texas Department of State Health Services] was notified by the licensee that a medical event had occurred earlier that day.
"The event occurred when the licensee attempted to treat a patient with 220 grays of Yttrium-90 (TheraSphere) microspheres. After the treatment the injection catheter was removed from the device and placed in a storage container. A survey of the container indicated the dose rate was half of the dose rate prior to injection. The licensee stated they believe only 107.1 Grays of the spheres had been injected into the patient.
"The licensee did not provide the target organ, but will provide it in the written report. The licensee stated the patient would not experience any adverse effects from the event. The licensee stated no individual performing the treatment received any significant exposure. The licensee stated the area was not contaminated. The licensee did not have a cause for the event, but will provide it once determined. Additional information will be provided as it is received in accordance with SA-300."

"At 1420 [EST] on November 24, 2018, operators discovered that a door was blocked open creating a breach of the auxiliary building secondary containment enclosure (ABSCE) boundary that exceeded the allowed ABSCE breach margin [of three minutes]. As a result, Unit 1 entered Technical Specification Limiting Condition of Operation (LCO) 3.7.12 Condition B for two trains of Auxiliary Building Gas Treatment System (ABGTS) inoperable due to an inoperable ABSCE boundary in MODE 1, 2, 3, or 4, and both Units entered Condition E for one required ABGTS train inoperable with fuel stored in the spent fuel pool.
"In MODES 1, 2, 3, and 4, the analysis of the loss of coolant accident (LOCA) assumes that radioactive materials leaked from the Emergency Core Cooling System are filtered and absorbed by the ABGTS. For the fuel handling accident, the analysis assumes that the ABSCE boundary is capable of being established to ensure releases from the auxiliary and containment buildings are consistent with the dose consequence analysis.
"The event is reportable in accordance with 10 CFR 50.72(b)(3)(v) as an event or condition that could have prevented fulfillment of the safety function of structures or systems that are needed to: (C) control the release of radioactive material and (D) mitigate the consequences of an accident.
"No actual LOCA or fuel handling accident occurred while both trains of ABGTS were inoperable. The condition had no impact on the health and safety of the public.
"The NRC Resident Inspector has been notified."
This situation occurred because of maintenance activities. A breeching permit had been initiated however, the required personnel to ensure the door could be closed within the required three minutes were not assigned. The door was closed approximately 15 minutes after the situation was noticed. |

"On 11/24/18 at 2015 EST, a loss of Control Room Envelope (CRE) was declared due to failure of the control room boundary door, 204-36-008. [Abnormal Operating Procedure 8588A Mitigating Actions for Control Boundary Breach was implemented]. The door was repaired at 2030 EST, restoring CRE to operable [status]."
A mechanical failure of the control room door latch prevented the door from closing.

"The purpose of this call is to retract a report made on November 25, 2018, NRC Event Number EN53752.
"NRC Event Report number EN53752 describes a condition at Millstone Power Station Unit 2 (MPS2) in which a control room envelope boundary door was discovered to not be able to fully close due to the latching mechanism being stuck in the extended position.
"The condition was reported to the NRC pursuant to 10 CFR 50.72(b)(3)(v)(D) via an 8-hour prompt report as an event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.
"Upon further review, MPS2 determined that there was no loss of safety function. An engineering evaluation determined that even with the control room boundary door unable to be fully closed due to the latching mechanism being stuck in the extended position, control room air in-leakage would not have been sufficient to prevent the control room emergency ventilation system from performing its safety function.
"Therefore, this condition is not reportable and NRC Event Number EN53752 is being retracted.
"The basis for this conclusion has been provided to the NRC Resident Inspector."

"At 1036 EDT, Sequoyah Nuclear Plant (SQN) terminated the Notification Of Unusual Event (NOUE) due to initial report of heat and smoke in Unit 2 Lower Containment.
"At 1000 EDT, it was determined that no fire had occurred. Due to difficulty of access to some of the areas being searched, the source could not be identified prior to 1000 EDT. No visible flame (heat or light) was observed.
"The source of the smoke was determined to be residual oil from a hydraulic tool oil in contact with pressurizer piping. The pressurizer piping was being heated up to support Unit 2 start-up following U2R22 refueling outage. Once the residual oil dissipated, the smoke stopped. It has been concluded that no fire or emergency condition existed.
"Unit 2 is currently in Mode 5, maintaining reactor coolant temperature 160F-170F and pressure 325psig-350psig with 2A Residual Heat Removal (RHR) system in service in accordance with U2R22 refueling outage plan."

"Sequoyah Nuclear Plant (SQN) is retracting this notification based on the following additional information not available at the time of the notification:
"Following a full Reactor Building inspection, it was concluded that a fire did not exist. The source of the smoke originally reported was later determined to be residual oil from a hydraulic tool in contact with pressurizer piping. Once the residual oil dissipated, the smoke stopped. The source of heat originally reported was normal heated conditions associated with the pressurizer commensurate with plant conditions. SQN reported initially based on the available information at the time and to ensure timeliness with emergency declaration and reporting notification requirements."
