ABSTRACT
The primary mission of the Reduced
Enrichment in Research and Test Reactors (RERTR) Program is to facilitate the
conversion of research and test reactor fuel and targets from high-enriched
uranium (HEU) to low-enriched uranium (LEU).
One of the current goals at Argonne National Laboratory (ANL) is to
convert 99Mo production at Argentine Comisión Nacional de Energía
Atómica (CNEA) from HEU to LEU targets.
Specifically addressed in this paper is ANL R&D related to this
conversion: (1) designing a prototype production vessel for digesting
irradiated LEU foils in alkaline solutions, (2) developing means to improve
digestion efficiency, and (3) modifying ion-exchange processes used in the CNEA
recovery and purification of 99Mo to deal with the lower volumes
generated from LEU‑foil digestion
