NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - DAMAGED GAUGE
The following information was obtained from the state of Washington via email:
"Earth Solutions NW (ESNW) reported that a moisture/density gauge (CPN model MC-1-DR, serial #MD60308232) was crushed on 7/2/2013 at temporary jobsite in Mill Creek, Washington. The gauge contained a 1.85 GBq (50 mCi) Am-Be source (model CPN-131, serial #AM8232) and a 0.37 GBq (10 mCi) Cs-137 source (model CPN-131, serial #C8232). The gauge operator had placed the gauge in front of his truck. When asked to move his truck, he forgot about the gauge, moved the truck forward, and crushed the gauge. The source rod was retrieved using a shovel and placed in a bucket of sand. Radiation surveys revealed no radioactive contamination at the jobsite. The source rod and other parts of the gauge were returned to the ESNW facility. On 7/17/2013, Hevly Technical Services (gauge contractor) and Washington Department of Health personnel performed leak tests on the Cs-137 and Am-Be sources. Washington State Public Health Laboratories analyzed the leak test samples and detected no radioactivity. The Cs-137 source rod was reinserted into the gauge body and secured with duct tape. The gauge was then placed into its shipping container. Hevly Technical Services transported the gauge to Qal-Tek Associates (radioactive waste broker) for disposal. To prevent recurrence, ESNW provided additional training to gauge users on proper handling, transporting, storage, and emergency procedures."

NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - PATIENT RECEIVED DOSE LESS THAN PRESCRIBED DOSE
The following information was obtained from the state of Washington via email:
"Swedish Medical Center (SMC) reported that a patient prescribed to receive 725 MBq (19.59 mCi) of Y-90 microspheres (Sirtex Medical model SIR-Spheres) to the left lobe of the liver, only received 370 MBq (10 mCi). SMC planned a two-artery feed, using 360 MBq (9.73 mCi) per artery per sub lobe. The written directive called for a total of 725 MBq (19.59 mCi) split into two doses. The certified nuclear medicine technologist who drew the dose did not properly review the written directive's instruction to split the total dose into two doses. Instead, the technologist split 370 MBq (10 mCi) into two doses of 190 and 180 MBq (5.14 and 4.86 mCi), respectively. Prior to patient administration, the radiation oncologist also failed to check the drawn doses prior to injecting them. The incident was identified post-injection when the remaining 360 MBq (9.73 mCi) of the original 725 MBq (19.59 mCi) was discovered. The physicians involved believe that the diminished dose may still provide the treatment sought. They will follow up on the patient in six months and will, if deemed necessary, retreat the liver lesions. The referring physician and patient were informed of the incident. SMC's investigation identified several errors: lack of comprehension regarding the dose draw worksheet, miscommunication and failure to review the written directive prior to correcting a dose, and failure to perform a safety pause and properly review the dose to be administered against the written directive prior to administration. Corrective actions included modifying the dose draw spreadsheet, training the nuclear medicine department with regards to the spreadsheet, and modifying the treatment record sheet to include a formal procedural pause prior to administration. The Washington Department of Health, Office of Radiation Protection, did not anticipate conducting an onsite investigation."

"At 0248 [EDT], with the plant shutdown in Mode 4, Nine Mile Point Unit 2 experienced a partial loss of off-site power during relay testing that resulted in an automatic start of the Division 2 Emergency Diesel Generator. All systems responded as expected for the event. The cause is being investigated. The station responded in accordance with appropriate Special Operating Procedures and restored impacted systems.
"This event is being reported in accordance with 10CFR50.72(b)(3)(iv)(A)"
At the time of the report, the emergency diesel generators are loaded and supplying plant safety equipment.
The licensee has notified the state of New York Emergency Management Agency and the NRC Resident Inspector. |

"Unit 3 experienced a loss of AC power while in Mode 6. Power was regained automatically from Keowee via the underground path.
"Decay heat removal has been restored. Spent fuel cooling has been restored.
"Emergency procedures [are] in progress."
The Licensee notified the senior NRC resident inspector, State of South Carolina and local authorities.
The total loss of 4160 volt AC power was for approximately 30 seconds. The unit is refueled and reactor reassembly complete up to bolting on the reactor head. There was no effect on Units 1 and 2.

At 0530 EDT, Oconee terminated the notification of unusual event on Unit 3. The basis for termination was that offsite power was restored and the plant is now in its normal shutdown electrical lineup.
The licensee has notified Oconee and Pickens counties and will be notifying the NRC Resident Inspector.

"At 1011 EDT on May 11, 2018, Containment Shield Building Annulus differential pressure exceeded the required limit. The Shield Building was declared inoperable requiring entry into Technical Specification (TS) 3.6.15 Conditions A and B. The event was initiated by failure of the operating annulus vacuum fan. Main Control Room Operators manually started the stand-by annulus vacuum fan to recover pressure. Shield Building Annulus differential pressure was restored to the required value at 1016 EDT and TS 3.6.15 Condition A and B were exited on May 11, 2018 at 1016 EDT.
"The failure mechanism for the annulus vacuum fan is being investigated.
"The Containment Shield Building ensures the release of radioactive material from the containment atmosphere is restricted to those leakage paths and associated leakage rates assumed in the accident analysis during a Loss of Coolant Accident (LOCA). The Emergency Gas Treatment System (EGTS) would have automatically started and performed its design function to maintain the Shield Building Annulus differential pressure within required limits.
"The event is being reported pursuant to 10 CFR 50.72(b)(3)(v)(C) and 10 CFR 50.72(b)(3)(v)(D). The NRC Resident has been notified." | |
