| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - LOST RADIOACTIVE SEED
The following was received from the Commonwealth of Pennsylvania via email:
"The licensee discovered the event on November 23, 2015 and notified the Department [Commonwealth of Pennsylvania] on November 25, 2015. It is reportable as per 10 CFR 20.2201(a)(1)(ii).
"An iodine-125 (I-125) seed was used for radioactive seed localization of a breast lesion. After surgical excision of the breast tissue at an outpatient surgical center, the specimen was placed in a plastic bag and imaged radiographically to confirm the presence of the seed. The seed was noted to be at the edge of the specimen. The specimen was then transferred to a plastic container for transport to the main hospital pathology department. When the specimen was received at pathology, a survey indicated that there was no seed present.
"Radionuclide: I-125 Seed
"Manufacturer: Best Medical
"Model No.: 2301
"Activity: 113 microCi
"The licensee assumes the seed became separated from the specimen and remained in the plastic bag which was disposed as biohazardous waste. A survey of the surgical center was performed, but the seed was not able to be located.
"A reactive inspection is planned by the Department. More information will be provided upon receipt."
Event Report ID No: PA150030
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.

"On December 3, 2015 at 2107 [EST], the Control Room Emergency Ventilation System (CREVS) was declared inoperable due to a higher than allowed identified in-leakage rate for the Control Room Envelope (CRE) when in the Normal Operating Mode. Both Unit 1 & Unit 2 remain at 100 percent power and they share a common CRE.
"At the time of discovery, there is a reasonable expectation this condition could prevent the fulfillment of the safety function of a system that is required to mitigate the consequences of an accident, thus satisfying the reporting criteria for 10CFR50.72(b)(3)(v)(D).
"Actions to implement mitigating actions were immediately initiated in accordance with Technical Specification 3.7.10. CREVS has been placed in Recirculation Ventilation Mode, isolating the control room from outside air.
"The NRC Senior Resident Inspector has been notified of the condition." | |
