In situ in-reactor testing of fusion materials and components

Abstract: Radiation hardness assurance for ITER is based on extensive radiation testing. To be representative, these tests must involve an in situ follow-up of the radiation induced changes. SCK·CEN—the Belgian Nuclear Research Center is operating different irradiation facilities with broad possibilities of environmental control and on-line instrumentation. We describe those facilities and outline several recently completed and on-going experiments to illustrate capabilities for testing under conditions relevant for ITER. [Copyright &y& Elsevier]
