Abstract

Abstract The minor actinides (MA) accumulated in the spent nuclear fuel of LWR are considered as very hazardous nuclear waste. One of potential options of their neutralization is a transmutation in accelerator driven systems (ADS). In the framework of the integrated project EUROTRANS (the 6th Framework Program of EURATOM) the European Facility for Industrial Transmutation (EFIT) of MA is being developed. One of the most important issues in this project is design and optimization of the fuel dedicated to MA transmutation. Two composite fuel candidates: CerCER with MgO-matrix and CerMET with Mo-matrix, both with (Pu,Np,Am,Cm)O2-x fuel particles, were selected for detailed studies and optimization. In the adopted strategy of MA burning it was postulated that Pu balance has to be close to zero by the end of fuel residence time. In order to fulfill this requirement, the composition of both candidates, the fuel element design and the cycle duration in EFIT with thermal power of 400-600 MW were optimized. An option to use the natural molybdenum as matrix in the CerMET fuel was also analysed, aiming the reduction of the fuel cost.
