“…Deuterium-Lithium sources: like IFMIF [11], Internation Fusion Materials Irradiation Facility/DEMO Orientated Neutron Scource (IFMIF/DONES) [12,13] or other similar facilities [14,15] as well as fusion-dedicated material irradiation facilities [16] are very important and will contribute substantially to gaining information about the degradation of material properties under neutron exposure at high neutron fluence that DEMO blankets will experience. This is deemed mandatory for materials qualification and the development of licensing codes.…”

The purpose of this paper is to critically review the testing and qualification strategy for the DEMO breeding blanket in Europe, identifying the potential risks and weaknesses and recommending, where necessary, the changes required to strengthen or accelerate the programme. Based on the information presented in this paper, a risk mitigation strategy is required to reduce the technological, licencing, and regulatory risks associated with the performance and reliability of the breeding blanket technologies for DEMO. An attractive mitigation option, which was originally proposed more than 30 years ago, but that was not implemented, is to perform testing and qualification of breeding blanket technologies and design concepts in a dedicated nuclear plasma device that serves as a 14 MeV Volumetric Neutron Source (VNS).

The IFMIF-DONES fusion oriented neutron source: evolution of the design

et al. 2021

View full text Add to dashboard Cite

IFMIF-DONES is a powerful neutron irradiation facility for the study and qualification of materials planned as part of the European roadmap to fusion-generated electricity. Its main goal is to study properties of materials under severe irradiation in a neutron field similar to the one in a fusion reactor first wall. It is a key facility to prepare for the construction of the DEMO power plant envisaged to follow ITER. The decision to start the construction of IFMIF-DONES is expected imminent. In this paper we present and discuss several key technical studies and decisions to improve and optimize the engineering design of IFMIF-DONES which were carried out as part of the activities in the framework of the EUROfusion Early Neutron Source work package (2015–2020). The following topics are discussed in this paper: the new layout of the IFMIF-DONES SRF LINAC accelerator and high-energy beam transport line, 7Be impurity management approach for the lithium loop, a maintainable test cell concept, a revised layout of the access cell for the remote maintenance operations, and facilities for complementary experiments.

“…Table 1 summarized the goal of the beam characterizations of LIPAc. In addition, for earlier realization of the neutron source for the material irradiation test, Fusion Neutron Source Design (FNSD) activities such as IFMIF/DONES in Granada, Spain and A-FNS in Rokkasho, Japan have been started [5,6]. Thus, all the results, experiences and lessons learned and to be learned from the LIPAc will be used for those accelerator designs as well.…”

The Linear International Fusion Materials Irradiation Facility Prototype Accelerator (LIPAc) is under commissioning in Rokkasho Fusion Institute in Japan and aims to accelerate 125 mA D+ at 9 MeV in Continuous Wave mode for validating the IFMIF accelerator design. To ensure a fine characterization and tuning of the machine many beam diagnostics are installed spanning from injector to the beam dump. The beam operations in 1.0 ms pulsed D+ at 5 MeV were successfully completed with a low power beam dump in 2019. Despite the challenges posed by the pandemic, the crucial transition to a new LINAC configuration was also finalized to enable operation in 1.0 ms — CW D+ at 5 MeV with the high-power beam dump. The 1st beam operation of the configuration was carried out in 2021. The experiences and challenges encountered during these beam campaigns are described in this paper.
