Description
As the complementary work of IFMIF-EVEDA (International Fusion Material Irradiation Facility- Engineering Validation and Engineering Design Activities) project, WPENS (Work Package Early Neutron Source) project in the framework of EUROfusion activities is committed to the engineering design of an IFMIF-DONES (Demo Oriented Neutron Source) facility, which is an accelerator based intense fusion-like neutron source with the objective of qualifying structural materials that will be used in the DEMO fusion reactor. The test cell (TC) in IFMIF-DONES is the central place as the meeting point of the three major systems (test systems, lithium systems, and accelerator systems) to host the irradiation test module, lithium target assembly (TA) and the end section of the accelerator. Although the reference TC design of IFMIF-DONES, in a large extent, inherits that of IFMIF-EVEDA, design justifications have been proposed with the consideration of the issues on stability of the lithium flow, activation and maintainability of key components, configuration of TC biological shielding, arrangement of in-cell components, impacts on other systems, dose rates in adjacent rooms, and etc. Special attentions are put on the location selection of the lithium quench tank (QT), the shape of the connection channel between the TA and the QT, and the configuration of TC floor. In this paper, the advantages and drawbacks of the reference TC design as well as the proposed design justifications have been investigated and discussed based on updated CFD and neutronic calculations under IFMIF-DONES condition. As the output of the investigations and analysis, a converged IFMIF-DONES TC design has been derived and is described in this paper.
