Chris Wagner: The role of Eden Radioisotopes in the future of nuclear medicine
Chris Wagner has more than 40 years of experience in nuclear medicine, beginning as a clinical practitioner before moving into leadership roles at companies like Mallinckrodt (now Curium) and Nordion. His knowledge of both the clinical and the manufacturing sides of nuclear medicine laid the groundwork for helping to found Eden Radioisotopes, a start-up venture that intends to make diagnostic and therapeutic raw material medical isotopes like molybdenum-99 and lutetium-177.

The Transient Reactor Test (TREAT) Facility is a graphite reactor capable of delivering tailored power histories to unique experiment designs. Frequently, these experiments are designed to simulate a specific reactor transient to perform detailed studies of reactor fuel behavior. The reactor core is uniquely designed to allow a limited energy release and resulting peak fuel cladding temperature such that thermal feedback mechanisms shut the reactor power transient down in a passive manner, thus maximizing the lifetime of the reactor fuel cladding. The reactor is air cooled; however, the cooling system does not serve a safety function. The air cooling is typically used for four main functions: (1) accelerate cooling of the reactor core to ambient temperature post transient operations, (2) remove activated gases from the reactor cavity, (3) perform heat balance for power calibration, and (4) maintain criticality on extended steady-state runs or shaped transients. With the restart of the reactor, these systems are now fully operational and have been exercised during the past year for the first time in more than 20 years. This paper summarizes the thermal properties of the core and the thermal-hydraulic design of the TREAT Facility and presents selected results of temperature profiles resulting from operation. Conservatively estimated maximum transient energy and steady-state power is provided.
