The conceptual design of the European Facility for Industrial Transmutation, EFIT has been carried out in the framework of the EUROTRANS European Integrated Project for the study of a European Transmutation Demonstrator, ETD, a modular sub-critical system for high level waste burning. The present configuration considered for evaluation is a 400 MWth lead cooled sub-critical reactor, loaded with Uranium-Free MA-based (about 50%) oxide fuel, with at least –3000 pcm of reactivity, any time, and a target variation for k-effective of about 300 pcm/cycle (1 year). The fuel composition and geometry have been optimised in order to reduce the radial peak factor, enhancing the burning efficiency with respect to a short-life core (3-5 years). The Beginning Of Life (BOL), Beginning Of Cycle (BOC) and End Of Cycle (EOC) configurations were studied with the Monte Carlo MCNP-5 code for criticality calculations, in order to complement the reference calculations performed with the ERANOS deterministic code.

Abstract
The conceptual design of the European Facility for Industrial Transmutation, EFIT has been carried out in the framework of the EUROTRANS European Integrated Project for the study of a European Transmutation Demonstrator, ETD, a modular sub-critical system for high level waste burning. The present configuration considered for evaluation is a 400 MWth lead cooled sub-critical reactor, loaded with Uranium-Free MA-based (about 50%) oxide fuel, with at least –3000 pcm of reactivity, any time, and a target variation for k-effective of about 300 pcm/cycle (1 year). The fuel composition and geometry have been optimised in order to reduce the radial peak factor, enhancing the burning efficiency with respect to a short-life core (3-5 years). The Beginning Of Life (BOL), Beginning Of Cycle (BOC) and End Of Cycle (EOC) configurations were studied with the Monte Carlo MCNP-5 code for criticality calculations, in order to complement the reference calculations performed with the ERANOS deterministic code.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
