CDT/FASTEF Task 1.2 state of the art at the end of WP1

This work has been carried out in the framework of the CDT/FASTEF EU FP7 project: it deals with the preliminary FA/core design far MYRRHA-FASTEF, a 100 MW LBE cooled reactor (working in both critical and sub-critical modes) that should be able to demonstrate transmutation and associated technology. This analysis is focused on the critical option, even if the main features of the sub-critical one (having the same FA structure) have to be foreseen since the beginning. The present report summarizes the state of the art of the project at the end of WP1 - Task 1.2. The neutronic and T/H analyses (carried out by the ERANOS 2.1 and RELAP codes, respectively) identify the range of feasibility for FASTEF. The remaining uncertainties (pointed out by this study) will be addressed during the WP2, when the FA design will be frozen and the MCNPX reactor model will be available. The second part of the presentation (done at the kick off meeting of WP2, on 9-10 March 2010 in Brussels) defines the work plan for the WP2 - Task 2.2 (in which ENEA is responsible as in Task 1.2).
