Dissolution of HFIR control plates

Creators

Description

A process was developed for the dissolution of High Flux Isotope Reactor (HFIR) control plates. These plates consist of aluminum metal, intensely radioactive europium oxide, and a small amount of tantalum metal. The radioactive solution will be diluted, mixed with grout, and disposed of by shale fracture. The plates are dissolved in nitric acid using a mercury catalyst. Conditions were determined that would produce a reaction rate compatible with existing equipment. 3 references, 1 figure, 3 tables
