Partitioning and Transmutation (P&T) aim to reduce the inventories of long-lived radionuclides (actinides and long lived fission products) in radioactive waste by transmuting them into radionuclides with a shorter half-life in dedicated burners.

In the framework of the specific programme 'Nuclear fission safety 1994-98', nine projects lasting three years on average have been covering these tasks; five in the field of strategy studies, two in partitioning techniques and two in transmutation techniques. The strategy studies aimed at assessing the capabilities of different burners (critical reactors and accelerator-driven systems) and fuel cycle double strata (thorium fuel) to limit the production or even destroy the stock of actinides (plutonium and minor actinides).

The two projects on transmutation dealt with the fabrication and irradiation of americium oxide fuel in an inert matrix in the high-flux reactor in Pet ten and the adiabatic resonance crossing method for long lived fission product incineration in CERN.

This report gives an overview of the main achievements of the research activities on P& T from 1994 to 1998, together with the executive summaries of the nine projects. Some conclusions are drawn from the scientific and technical results obtained during this period, which have been used for the preparation of the work programme on p & T in the fifth framework programme (1998-2002).

The work on partitioning included synthesis of new molecules for minor actinide extraction (e.g. macrocycles, heterocyclic poly-nitrogen ligands) and testing of their selectivity on high-level liquid waste.
