This work was carried out in the framework of the EU FP7 CDT project: it deals with the core design of a LBE cooled reactor (FASTEF) that should be able to demonstrate transmutation and associated technology through a system working in sub-critical and/or criticai mode.

In spite of the planned work (see title), and since the project is strictly linked with the design of the MYRRHA reactor (planned to be built by 2023 at SCK-CEN research centre in Mol, B), the last year of activities was devoted to characterisation studies in ADS mode. Therefore, thanks to an additional effort by all the partners, the outcome of the present work (D2.2) is a detailed analysis of MYRRHA-FASTEF working in both critical and sub-critical modes.

Abstract

This work was carried out in the framework of the EU FP7 CDT project: it deals with the core design of a LBE cooled reactor (FASTEF) that should be able to demonstrate transmutation and associated technology through a system working in sub-critical and/or criticai mode. The aim of Task 2.2 was to identify the design changes to operate in criticai mode, starting from the XT-ADS sub-critical core defined in the EU FP6 EUROTRANS project. Actually, the FA / core / reactor design were significantly modified during the WP1 phase and at the beginning of WP2 (e.g.: from 57 MW up to 100 MW core power, enhanced flexibility, etc.). Afterwards, a detailed characterisation (neutronic, TH, TM, shielding and activation analyses) was performed by choosing, as reference layout, the max envelope of the criticai core. In spite of the planned work (see title), and since the project is strictly linked with the design of the MYRRHA reactor (planned to be built by 2023 at SCK-CEN research centre in Mol, B), the last year of activities was devoted to characterisation studies in ADS mode. Therefore, thanks to an additional effort by all the partners, the outcome of the present work (D2.2) is a detailed analysis of MYRRHA-FASTEF working in both critical and sub-critical modes.
