| AGREEMENT STATE REPORT - RAM PACKAGES SWITCHED IN ERROR The following email was received from the Massachusetts Radiation Control Program (the agency) via email: "On August 5, 2020, InviCRO reported receiving in error on same day a White I package of 140 mCi Lu-177. Receipt survey recorded a package surface dose rate of 0.2 mRem/hr. The received package activity exceeded their license radioactive material possession limit of 125 mCi. Package held by licensee in secure storage until activity falls below license limit (Lu-177 half-life is 6.7 days). The intended activity as requested by the licensee was 60 mCi. Package ordered through Radiomedix in Texas who forwarded order to supplier (ITM Medical isotopes GmbH) in Germany. Package sent from Germany arrived in [common carrier] US facility and directly forwarded to customer without going through Texas. Agency contacted [common carrier] and Texas Department of State Health Services. Apparent cause was [common carrier] accidentally switching labels/paperwork on two similar Lu-177 packages. The package originally intended for InviCRO was forwarded to a customer licensed in Indiana. Indiana customer (Endocyte) notified by Radiomedix. All US parties identified above are aware of incident. Radiomedix continuing its internal investigation. Agency left detailed voicemail messages (including circumstances, package receipt date and activity) at Indiana Department of Homeland Security and Indiana Department of Health. Agency determined this to be a 30-day reportable event and considers this event currently still open." MA Event Number: 20-4230 |

| REACTOR SCRAM AFTER LOSS OF FEEDWATER - GRAND GULF "On August 24, 2020 at 2305 CT at Grand Gulf Nuclear Station (GGNS) an Automatic Reactor Scram occurred after a trip of the Reactor Feed Pump B and subsequent lowering of reactor water level to 11.4 inches Narrow Range. The scram occurred with Reactor Power at 14% and the main generator offline. "All control rods fully inserted and there were no complications. All systems responded as designed. "Main Steam Isolation Valves were manually closed to control reactor cooldown, Currently GGNS reactor pressure is being maintained at 450-600psig. Reactor water level is being maintained with condensate through startup level control. "No radiological releases have occurred due to this event from the unit. "The NRC Resident has been notified." Decay heat is being removed via the main condenser. Notified R4DO. |
