TERMINAL REPORT-DESIGN OF A DAREX DISSOLUTION FACILITY IN ORNL BLDG. 3019 FOR ENRICHED POWER REACTOR FUEL ELEMENTS

Technical Report ·
OSTI ID:4210168

The design drawings and specifications for a Darex pilot plant to be constructed at ORNL were about 75% complete when the project was terminated in September 1959. As a feed preparation step, this plant was designed to dissolve enriched, stainless-steel-clad, power reactor fuel elements in dilute aqua regia. The pilot plant design included a dissolver column, evaporator, clarifier, scrubbers, storage vessels, and condensers, for a total of about 31 major pieces of equipment, of which about 16 were to be constructed of titanium and most of the remainder of Type 304L stainless steel. These were arranged into nine units inside the cell and in three major service areas outside the cell. The unitized concept for arrangement of the cell equipment reduced the required number of high- grade field welds significantly. About 50 drawings were essentially completed and five specifications were written. This terminal report emphasizes the phases of the mechanical design having general application tc other Darex facilities. (auth)
