Abstract

This paper describes the PETRA hot cell facility currently undergoing commissioning tests at the JRC-Ispra Establishment and illustrates the possibilities and objectives of experimental work that can be carried out in the field of radioactive waste management. The facility includes the typical HA-process steps of nuclear fuel reprocessing, i.e. dissolution, filtration, co-decontamination with on-line solvent regeneration) for the production of significant quantities of both medium and high level liquid and solid waste. These are to be used primarily for optimisation, cerification and demonstration studies at full radioactivity levels, for the study of safety and reliability of waste confinement and disposal. The facility operates on fuel batches of 6 kg low enriched U equivalent in a sequential processing mode. The waste streams can be treated by further extraction, concentration, precipitation, denitration and vitrification either as a whole or as separate fractions.
