JUPITER Pilot Plant

The 2-kg HM/day JUPITER pilot plant being built by Merz and associates [M7] at Julich will test a flow sheet for reprocessing high-burnup graphite-clad fuel generally similar to the two-stage process just described. In addition, the pilot plant will demonstrate fluidized-bed combustion of crushed gTaphite-clad fuel assemblies and refabrication of fuel from recovered uranium and thorium. Radiokrypton in combustion off-gases will be recovered by cryogenic absorption in liquid C02, and tritiated water vapor by adsorption on molecular sieves.
