WAA's position in the nuclear industry

The Jülich reprocessing plant (JUPITER) was a German nuclear facility for the reprocessing of nuclear fuels . It was a pilot plant for the reprocessing of the spent fuel element balls from the test nuclear power plant AVR (Jülich) and the thorium high-temperature reactor in Hamm .

history

As part of the research and development work on the uranium - thorium fuel cycle, the Jülich nuclear research facility is building the JUPITER semi-technical test facility.

The "JUPITER" pilot plant (Juelich Pilot Plant for Thorium Element Reprocessing) in Jülich was built for the pebble bed reactors AVR (Jülich) and the THTR-300 nuclear power plant in Hamm. The WAA was completed, but never went into "hot" operation because a mistake in the structure of the spherical fuel elements made the processed fuel unusable for reuse in pebble bed reactors.

It was expected that cold operation would start at the end of 1976 and that “hot” test operation would start at the end of 1977. The plant was dismantled by 1990.

technology

Graphite ball for high temperature reactor

In addition to the main components (incinerator to remove the carbon coating, dissolver, evaporator to adjust the feed solution, mixer settler ), the system also contained facilities for cleaning the combustion and dissolving waste gases, for recovering the nitric acid produced during the feed solution adjustment and for solvent washing . The system contained five mixer settlers and an intermediate evaporator and allowed with this equipment, the study of different extraction - flow diagrams . The capacity of the plant was set at approx. 2 kg of heavy metal oxide per day. That corresponded to 330 AVR fuel elements per day.
