IFMIF/EVEDA achievements overview

Abstract

The International Fusion Materials Irradiation Facility (IFMIF) is conceived to generate fusion relevant neutrons with a broad peak at 14.1 MeV through Li(d,xn) nuclear reactions. IFMIF will enable high intensity neutrons to irradiate materials at above 20 dpa/fpy (displacement per atom per full power year) of a volume around 500 cm3 in the high flux test module. IFMIF is presently in its Engineering Validation and Engineering Design Activities (EVEDA) phase under the Broader Approach (BA) Agreement signed between EURATOM and Japanese Government in 2007. This agreement mandates to validate the design of the different systems of IFMIF and to produce an integrated engineering design of IFMIF, together with the data necessary for future decisions on the construction and operation of the plant. While the Engineering Validation Activity (EVA) of the Lithium Target Facility and the Test Facility was completed by constructing prototypes, the EVA of the Accelerator Prototype Facility with the Linear IFMIF Prototype Accelerator (LIPAc) is still on-going. This article overviews the achievements in the previous phase ended on 31 March 2020 and the progress in a new phase to complete the commissioning of the LIPAc and to enhance the sub-systems in order to prepare for the design of the future Fusion Neutron Source facility.
