Overview of achievements and outlook of the IFMIF/EVEDA project

The Engineering Validation and Engineering Design Activities for the International Fusion Materials Irradiation Facility (IFMIF/EVEDA) project have been conducted as one of the three projects (IFMIF/EVEDA, IFERC and JT60SA) within the Broader Approach (BA) agreement between EURATOM and the Japanese government since 2007. The IFMIF is intended to deliver accelerator-based deuterium-lithium (D-Li) neutrons at energies and intensities sufficient to enable the qualification of candidate materials for future fusion energy reactors, such as DEMO. The primary objective of the IFMIF/EVEDA project is twofold: (i) to develop a detailed engineering design of the IFMIF and (ii) to validate its major components, namely the accelerator facility, the lithium target facility and the test facility. During Phase I of the BA, which concluded in March 2020, the engineering validation activity (EVA) for the lithium target facility and the test facility were successfully completed through the construction and testing of prototypes. In contrast, the EVA for the accelerator facility, implemented through the Linear IFMIF prototype accelerator (LIPAc), remains on-going. ... mehrThe current phase (Phase II) focuses on the continued commissioning of the LIPAc and the enhancement of some sub-systems to support the development of the Fusion Neutron Source Design (FNSD). This article presents an overview of the progress achieved in the LIPAc commissioning and FNSD activities and outlines the future directions of the activities.
