The following information was obtained from the state of Ohio via email:
"An I-125 seed, approximately 127 microCi, was retrieved from a breast seed localization patient on 6/20/18. A gamma probe was used during surgery to verify it was present in the tissue sample. After surgery the sample was x-rayed and surveyed to verify the seed was still present in the sample; the tissue was placed in a formalin tray and locked in a cabinet. Pathology dissected the tissue on 6/21/18 and did not find the seed. The licensee believes the seed was loosely attached to the tissue and was thrown away with the rest of the materials after it was x-rayed. The licensee performed surveys and did not locate the source. Due to the low activity of the source, it is not expected that the public dose limit would be exceeded."
Ohio NMED Report No.: OH180005
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 obtained from New York City Department of Health and Mental Hygiene, Office of Radiological Health via email:
"On June 25, 2018, a 65-year old male patient was treated with Y90 TheraSphere to the right side of the liver. The intended dose of administration was 64.8 mCi (2.4 GBq). Upon conclusion of the procedure, when the waste materials (delivery line, vial, gauze, etc.) was counted, it was found that 41.87 mCi (1.55 GBq) of Y90 TheraSphere was actually administered to the patient. In other words patient received 64.6% of intended dose. The Radiation Safety Office of Mount Sinai Hospital reported the incident to the New York City Department of Health and Mental Hygiene [NYCDOH] on 6/25/2018 at 1340 hrs. These findings were communicated to the patient and the referring physician within 24 hours. The licensee stated that no serious adverse events occurred and the patient will be followed up with Interventional Radiology as per protocol. The licensee indicated that the root cause analysis of the event is currently being performed and a detailed report of the event with corrective action will be sent to the NYCDOH within 15 days."
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. |

The following information was received from the State of Texas:
"During the review of an event, the Agency [Texas Department of State Health Services] found a letter from a licensee reporting the shutter on a Ohmart model SHD-45 containing a 50 millicurie cesium - 137 source had failed in the closed position. The report was dated November 29, 2017. The shutter did not pose an exposure risk to any individual. The licensee has worked with the manufacturer and the gauge was scheduled to be replaced on June 21, 2018. The Agency has not been able to confirm if the gauge was repaired/replaced. Additional information will be provided as it is received in accordance with SA-300."

The following information was obtained from the State of California via email:
"On 03/16/18, the Site Manager at Vallecitos Nuclear Center (VNC) contacted RHB [California Radiologic Health Branch] licensing unit to notify of an incident related to a shipment from their facility. The incident occurred a year ago on 03/24/17, where a shipment of Cf-252 sources with a TI [Transportation Index] of 19 was inadvertently not flagged as exclusive use. This was identified by CHP [California Highway Patrol] at a weigh station approximately 10 miles from VNC [in Livermore, CA] and the shipment was returned to the facility. VNC corrected the paperwork, calling the shipment out as exclusive use. VNC was cited by CHP. VNC has recently received a letter from Alameda County District Attorney's Office referencing a Vehicle Code and a Professional Code. RHB will be following up on this investigation regarding failure to immediately notify RHB and for failure to label the shipment as exclusive use.
"Note: Inspection unit at RHB was notified of this incident on 06/18/18."

"At 0954 [EDT] on July 3, 2018, with Unit 1 in Mode 1 at 100 percent power, the reactor was manually tripped due to high steam generator water level. The trip was not complex, with all systems responding normally. Operations stabilized the plant in Mode 3. Decay heat is being removed through the main steam lines through the steam dumps and into the condenser.
"The expected actuation of the Auxiliary Feedwater System (an engineered safety feature) is being reported as an eight hour report under 10 CFR 50.72 (b)(3)(iv)(A).
"Unit 2 was not affected.
"There was no impact to the health and safety of the public or plant personnel.

GEOFFREY MILLER (R4DO) | | Unit | SCRAM Code | RX Crit | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text DISCOVERY OF AN UNANALYZED CONDITION THAT SIGNIFICANTLY DEGRADES PLANT SAFETY
"On July 3, 2018, while performing a review of Emergency Operating Procedures, a concern was identified regarding the potential for excessive loss of ultimate heat sink inventory (UHS) through the auxiliary feedwater (AFW) system mini-flow recirculation pathway. This condition would have the potential to prevent the ultimate heat sink from providing an adequate inventory of water for a 30-day mission time.
"The normal water supply for the Callaway AFW system is the condensate storage tank (CST). The CST is a non-safety grade component. The safety-grade supply for AFW is the essential service water (ESW) system. The ESW system is supplied by the UHS. The UHS thermal performance analysis accounts for a loss of UHS inventory to the AFW system up until the point of the accident sequence that the AFW pumps would be secured. The analysis did not include an allowance for loss of UHS inventory through the AFW mini-flow recirculation pathway following the AFW pumps being secured. The EOP guidance that secures the AFW pumps does not isolate the mini-flow recirculation pathway.
"Initial estimates indicate that loss of UHS inventory through the mini-flow recirculation pathway, if not isolated, would preclude the UHS from completing its 30-day mission time. This potential for depletion of the UHS placed the plant in an unanalyzed condition that significantly degraded safety.
"Callaway has issued interim guidance to the on-shift personnel regarding this concern to ensure that the ultimate heat sink water level is maintained at a level that will be adequate to mitigate the potential loss of inventory.
"This condition is reportable per 10 CFR 50.72(b)(3)(ii)(B) for an unanalyzed condition that significantly degrades safety.
"The NRC Resident Inspectors have been notified of this condition."
* * * RETRACTION ON 07/31/2018 AT 1430 EDT FROM LEE YOUNG TO ANDREW WAUGH * * *
"Event Notification (EN) 53485, made on July 3, 2018, is being retracted because re-evaluation performed subsequent to the notification has demonstrated, based on actual plant equipment and environmental conditions, that the unanalyzed inventory losses previously reported by EN 53485 would not have depleted the UHS inventory to an unacceptable level during its 30-day mission time.
"The re-evaluation has led to the conclusion that the previously unanalyzed losses of UHS inventory would not have prevented the UHS from performing its specified safety functions and meeting its 30-day mission time requirements. With the UHS capable of performing its specified safety functions and meeting its 30-day mission time requirements, the systems supported by the UHS would have remained capable of performing their specified safety functions. Based on these considerations, it has been determined that the condition reported in EN 53485 did not result in the plant being in an unanalyzed condition that significantly degraded safety. Consequently, the condition did not meet the criteria for an 8-hour notification per 10 CFR 50.72(b)(3)(ii)(B) for an unanalyzed condition that significantly degrades safety.
"The NRC Resident Inspector has been notified of the Event Notification retraction."
