Abstract

This report summarises the results of work performed at the Institute for Transuranium Elements of the JRC in 1988. Studies with transient-tested LWR fuel were further extended, accompanied by investigations simulating the presence of fission products at high burn-up. An optimal procedure was sought for the fabrication of a fuel which can be operated safely up to high burn-up. Radiative properties of uranium oxide have been measured up to 4000K. The impact of recycling minor actinides was assessed. In large scale fire experiments, glove-box size pieces of "contaminated" plexiglass and other substrates were burnt. Tests were performed on the destruction of ammonium ions in solutions of nitride fuels for reprocessing and the extraction and purification of actinides from waste actinide mixtures. The search for new actinide materials with interesting magnetic properties was directed towards various ternary compounds. Equipment for analysis of fission products was developed and improvements made to the TRANSURANUS code. The characterisation of glass and cement matrices for nuclear waste continued, and an expert system was developed for the destructive analysis of fissile materials. Work for third parties and in support of Community policies included a large number of analyses performed for the EURATOM safeguards inspectorate.
