Abstract
One main objective of IP EUROTRANS is the conceptual design of so-called European Facility for Industrial Transmutation (EFIT) of minor actinides (Np, Am, Cm). Two composite fuel systems were identified: the first (CERCER) is composed of plutonium and MA oxides in solid solution, dispersed in the ceramic magnesia (MgO) matrix, in the second (CERMET) an identical fissile phase is hosted in a molybdenum (92Mo) metallic matrix. In this paper it is planned to study the hot fuel pin in EFIT core by using different fuel performance codes: TRANSURANUS, FEMALE and TRAFIC. The codes, we are dealing with, have been customized by introducing a set of correlations recommended in the IP EUROTRANS reports and published documents to model main thermal and mechanical properties of the EFIT materials such as T91 steel cladding, CERCER and CERMET fuels, lead coolant. At this step, the adopted fuel modelling is partly validated by using the results of the experimental thermo-physical measurements performed in the AFTRA domain. The predictions of selected fuel performance codes are discussed aiming at a preliminary evaluation of uncertainties, firstly at the beginning of fuel rod life, as a fundamental step for the future calculations at higher burnup.
