BACKGROUND
The development of core structural materials for fusion and advanced fission reactors will require the availability of suitable materials irradiation and testing facilities, and a supply of materials damaged under fusion and fast fission relevant conditions. The use of ion beam accelerators to simulate the intense neutron irradiations and high damages by fusion and fission neutron spectrums is helping to understand the main physical mechanisms of radiation damage resistance in materials.
During the last 10-15 years, many interesting experimental results on radiation swelling and creep, radiation hardening, and helium embrittlement of materials have been obtained under neutron and charged particle irradiations. However, a detailed comparison and understanding of these experimental results (temperature and dose dependencies, effects of accumulation of hydrogen and helium atoms in the matrix, etc) under neutron irradiations in fission reactors, spallation neutron sources and charged particle irradiations either does not exist or is very sparse.
- For the development of new future material technologies using charged particle accelerators, it is highly desirable and beneficial to improve consistency and correlations between ion beam radiation exposures and radiation damage effects in materials. There is a need to provide a better understanding of radiation effects and mechanisms of material damage and basic physics of accelerator irradiations under specified conditions, and to build more reliable and robust datasets by which to compare experimental results with computer simulations and theoretical modelling.
OBJECTIVES
The objective of this Technical Meeting is to enhance, through sharing of information and experience, the use of ion beam irradiations to effectively simulate neutron irradiations of future fusion and fission reactor materials at high damages. It is anticipated this will lead to an improvement in the standardization, comparison and evaluation of experimental data for a wider range of materials and for a greater range of operating conditions. Specific objectives are:
- To exchange recent results of research programs related to the fundamentals of radiation damage of core structural materials at high dpa; experimental, theoretical and computational
- To enhance the knowledge on applying ion beam irradiations to effectively simulate neutron irradiations at high dpa
- To better understand the dependency and evolution of radiation damage on irradiation conditions of ion beam type, energy, flux and fluence
- To better define observable quantities produced by ion beam irradiations that are important inputs for multi-scale modeling at engineering lengths and long time scales
- To help harmonize research efforts amongst interested Member States and research institutions
