AGREEMENT STATE REPORT - DAMAGED GAUGE

The following was received form the California Radiologic Health Branch (RHB) via email:

"On 7/17/2020, licensee's RSO [(Radiation Safety Officer)] contacted RHB to report an incident in which a portable nuclear gauge (Humboldt 5001EZ SN: 2919, 11 mCi Cs137, 44 mCi Am241:Be) was damaged by a construction truck at approximately 2330 PDT on 7/16/2020. The RSO secured the gauge after notification by the gauge technician and transported the gauge to the licensee's permanent storage location. The RSO determined and confirmed to RHB that the source rod was able to be retracted into the shielded position after the incident. The RSO performed a radiation survey and reported readings of 0.099 mR/hr at 1 meter. RHB will be following up with this investigation."

AGREEMENT STATE REPORT - LOST SHIPMENT OF I-125 SEEDS

The following was received from the Florida Bureau of Radiation Control (BRC) via email:

"[The licensee] called the BRC at around 0945 EDT to report that a package [containing 53.91 mCi of I-125] of Brachytherapy seeds was lost by [the common carrier]. The package left the manufacturing facility, then the local facility, was picked up by [the common carrier] at 1706 on July 20, 2020, but was lost somewhere before Tampa. IsoAid checked the delivery status on July 21, 2020, but it was not scanned. Route intended to be Tampa to Memphis to New York to South Africa.

"There are 100 seeds loaded in 7 magazines, 6 magazines contain 15 seeds each, and a 7th magazine contains 10 seeds. These seven magazines are contained in a white leaded pig. The pig was packaged in a white box, 9" x 7" x 5" weighing about 4lbs. The package was labeled as Radioactive White - I, UN2915."

Florida Incident Number: FL20-085

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.

EMERGENCY PROCEDURE ERROR POTENTIALLY PREVENTING TIMELY COMPLETION OF EMERGENCY CORE COOLING SYSTEM RECIRCULATION ALIGNMENT

"At 0815 CDT on 7/30/2020, it was determined that a procedural error in emergency procedure ES1.3, Transfer to Cold Leg Recirculation, could delay realignment from emergency core cooling system (ECCS) injection phase to recirculation phase under lower plant operational modes. It is noted this scenario is postulated to occur only when the boron dilution mitigation system is operable in lower modes of operation as per Technical Specification 3.3.9 (required operable in Mode 2 [below P-6], 3, 4 and 5). Current plant conditions require this feature nonfunctional so this issue does not impact current plant conditions. This condition is not bounded by existing design and licensing documents; however, it poses no current impact to the health and safety of the public or plant personnel. Therefore, this event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(ii)(B).

"The NRC Resident Inspector has been notified."
