Abstract

The PETRA plant is an experimental facility (fully active), intended for the implementation of various treatment and conditioning processes on waste streams (LWR fuel material at high burn-up (33000 MWd/t) for uranium and plutonium extraction; successive treatment of high active waste etc generated during the Purex type operations). Installation will be in the ADECO complex within the ESSOR reactor. Maximum throughput will be 10 batches of 6 kg U per annum. The proposed research programme emphasizes, in conformity with the general mandate of the JRC research objectives, safety aspects related to the management of long-lived fractions of radioactive waste, like the transuranium actinides or technetium. In-depth studies of both the pattern of individual isotopes (e.g. Np, Tc) over the complete process scheme and the behaviour of composite streams under particular process conditions (e.g. evolution of concentrated HAW composition) are scheduled. The facility is proposed in the frame of international collaboration agreement for fully active verifications of processes developed by other laboratories at simulated or tracer level.
