Event Notification Report for July 01, 2020

AGREEMENT STATE REPORT - MEDICAL EVENT

The following was received via email:

"A 98 microCurie I-125 breast cancer localization seed (titanium encapsulated) was inadvertently cut in half during its extraction from a patient. All portions of seed presumably removed and lavage performed. A pancake probe was used at tissue surface prior to tissue closure and measured 200 microR/hr. Tissue entry point was closed and re-surveyed at some later time with a measurement of 10 microR/hr. Post recovery, patient was apprised of the event and initiated a 10-day KI treatment plan. [The Radiation Safety Regional Health Director] is in consultation with the dose calibrator manufacturer and seed manufacturer (Team Best) in order to better calculate activity of recovered seed portions and subsequently compare to initial, inserted activity. The difference will yield activity remaining in the patient."

Florida Incident Number: FL20-073

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.

LOSS OF OFFSITE POWER - AUTO INITIATION OF EMERGENCY DIESEL GENERATOR

"At 2305 EDT on July 1, 2020, while in Mode 5 for Refueling Outage 20 with no core alterations in progress, Fermi 2 experienced a loss of Division 2 offsite power (345 kV) which resulted in a valid automatic initiation of the Division 2 Emergency Diesel Generators (EDG) 13 and 14. EDG 13 and 14 started as expected to supply their associated busses. Division 1 offsite power remains operable and powering the Division 1 Residual Heat Removal (RHR) system in Shutdown Cooling (SDC) mode of operation. Division 1 EDGs 11 and 12 remain operable and available.

"The cause of the loss of Division 2 offsite power is under review and has preliminarily been determined to be caused by Mayfly accumulation in and around the Division 2 (345 kV) switchyard. Actions have been put in place to minimize and deter Mayflies from gathering near plant switchyards.

"All systems responded as expected for the loss of Division 2 offsite power and no loss of SDC occurred. There was no impact to the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified.

"The event is reportable pursuant to 10 CFR 50.72(b)(3)(iv)(A), as a valid specified system actuation."

EN Revision Text: AGREEMENT STATE REPORT - ABANDONED RADIOACTIVE SCRAP METAL

The following information was received via email:

"On 7/1/2020, Massachusetts Radiation Control Program was informed by Schnitzer Steel Industries, Inc., that a scrap metal shipment from Town of Littleton Transfer Station in Littleton, MA set off the radiation monitor alarm. The vehicle was redirected back to Littleton Transfer Station for follow-up survey and mitigation in accordance with MA RCP DOT Special Permit 10656 MA-MA-20-01.

"On 7/6/20, the material was identified and segregated from the scrap metal load by an independent radiation consultant. The radioactive material discovered was radium-226 Aircraft gauge. Device is intact and not leaking as a wipe test was done by radiation consultant. A Ludlum Model 9DP-1 ion chamber was used for direct measurements on the instrument. The dose rate at 6 inches from the instrument was 1 mR/hr. Dose rate outside of drum is less than 300 microR/hr. The radium-226 activity was estimated to be approximately 31.6 microCuries based on the dose rate measured.

"The RAM material is being stored in safe secure storage away from people and labeled as radioactive material held for proper disposal.

"This activity meets the 30-day event report requirement for lost or abandoned radioactive material greater than 10 times the quantities specified in 10 CFR 20 Appendix C, or the Massachusetts equivalent, 105 CMR 120.297 Appendix C, which is ten times reportable quantity for radium-226 (1 microCurie).

"The Massachusetts Radiation Control Program considers this event to be open until proper disposal of this instrument is confirmed."

Event Docket No.: MA 19-4216

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.
