"On October 13, 2017 at 1700 CDT, Unit 1 High Pressure Coolant Injection (HPCI) was declared Inoperable due to discovery of a leak on a sensing line to 1-PCV-073-0043, Lube Oil Cooler & Gland Seal Condenser Pressure Control Valve. The leak is a steady stream located where the sense line connects to the valve.
"This constitutes an unplanned HPCI System inoperability and requires an 8 hour ENS notification in accordance with 10 CFR 50.72(b)(3)(v)(D), due to the failure of a single train system affecting accident mitigation and a 60 day written report in accordance with 10 CFR 50.73(a)(2)(v)(D)."

"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).
"TVA's evaluation of this event notification is documented in the corrective action program.
"The licensee has notified the NRC Resident lnspector."

"NRC notification 53340 was made to ensure that the Eight-Hour Non-Emergency reporting requirements of 10 CFR 50.72 were met when a leak was identified on U1 HPCls Gland Seal Condenser.
"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. Thus, there was no impact on nuclear safety. Therefore, this event is not reportable under 10 CFR 50.72(b)(3)(v)(B).

"Phone conversation with appraiser and son revealed the following:
"Deceased passed away years ago, and his wife, who has had her spouse's possessions since then, is moving from the Senior Center. Their son was given the name of an Estate Liquidator, to assess their belongings. The appraiser came across a metal shoe shine sized canister containing what he described as marble sized pellets and sandy glass, that had Plutonium marked on it. There also was a framed Reference letter addressed to the deceased from Robert Oppenheimer, thanking him for his contributions to The Manhattan Project. Unbeknownst to the son, the appraiser then contacted the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) with his concerns.
"The son stated that the material in the canister was fused sand from the Trinity test site, and did not know why the appraiser was concerned about it."

NMSS_EVENTS_NOTIFICATION (EMAIL) | | This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - DAMAGED TROXLER GAUGE
The following was received from the state of Texas via email:
"On May 30, 2018, the Agency [Texas Department of State Health Services] was notified by the licensee's radiation safety officer (RSO) that on May 29, 2018, a Troxler model 3440 moisture/density gauge was damaged at a field site. The gauge contains an 8 millicurie cesium-137 source and a 40 millicurie americium-241 source. While the gauge was in taking a measurement and the technician and the job site foreman were talking, a bobcat operator working in the area failed to see the gauge and ran over it. The RSO stated the foreman and technician attempted to stop the operator of the bobcat, but were unable to get his attention. The RSO stated the operating rod for the cesium source was slightly bent, but the technician was able to return the source to the shielded position. The RSO stated the gauge was surveyed and radiation levels were normal. The gauge was returned to the licensee's location in San Antonio, Texas, for storage. The manufacturer has been contacted for guidance on what to do with the gauge. Additional information will be provided as it is received in accordance with SA-300."
Texas Incident # - 9577
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.

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.
