Abstract

The International Fusion Materials Irradiation Facility - Demo Oriented NEutron Source (IFMIF-DONES) is a single-sited novel Research Infrastructure for testing, validation and qualification of the materials to be used in a fusion reactor. Recently, IFMIF-DONES has been declared of interest by ESFRI (European Strategy Forum on Research Infrastructures) and its European host city would be Granada (Spain). In spite the first and most important application of IFMIF-DONES related to fusion technology, the unprecedented neutron flux available could be exploited without modifying the routine operation of IFMIF-DONES. Thus, it is already planned an experimental hall for a complementary program with neutrons. Also, a complementary program on the use of the deuteron beam could help IFMIF-DONES to be more sustainable. In the present work, we study radioisotope production with deuterons of 177Lu. The results show the viability of IFMIF-DONES for such production in terms of the needs of a territory of small-medium size. Also the study suggests that new nuclear data at higher deuteron energies are mandatory for an accurate study in this field.

Highlights

IFMIF will be an installation for irradiation tests that will simulate the conditions inside a fusion reactor in terms of neutron fluence and neutron energy [1]
In order to reproduce the same hard radiation conditions inside a fusion reactor, it is necessary to build a specific neutron source based on the nuclear reaction that occurs between deuterium and lithium nuclei
The convection loss coefficient can be calculated as [18]: h where k f is the coefficient of thermal conductivity of the fluid, r is the radius of the target (1 cm), we have considered the same radius for the deuteron beam, ρ is the density of the water, μ is the dynamic viscosity of the fluid and cp is the specific heat at constant fluid pressure

Summary

Introduction

IFMIF will be an installation for irradiation tests that will simulate the conditions inside a fusion reactor in terms of neutron fluence and neutron energy [1]. In order to reproduce the same hard radiation conditions inside a fusion reactor, it is necessary to build a specific neutron source based on the nuclear reaction that occurs between deuterium and lithium nuclei. The need to build a first fusion reactor, ’early DEMO’, has imposed some urgency in the construction of a neutron irradiation plant. It was decided, in the European framework, the design and construction of a plant that was able to generated that level of damage. The IFMIF project will consist of two accelerators, DONES will consist of a single accelerator in an attempt to achieve this urgency
