Abstract

In order to study the influence of fast neutrons on the behaviour of high heat flux components for ITER, miniaturized samples have been neutron irradiated. Neutron fluences were 0.2 dpa in carbon/0.15 dpa in tungsten (irradiation campaign PARIDE 3) and 1 dpa in carbon/0.6 dpa in tungsten (irradiation campaign PARIDE 4). Irradiation temperatures were 200 °C approximately for all samples. The irradiated mock-ups as well as un-irradiated reference samples were tested under thermal fatigue conditions by means of a high power electron beam facility. They were loaded up to several thousand cycles and later they were cut and investigated by hot metallography. In addition to these thermal fatigue experiments, the degradation of thermal conductivities for plasma facing materials has been investigated. Samples from CFCs and tungsten alloys have been tested. Thermal diffusivities were measured by a laser flash method, heat capacities by differential scanning calorimetry. © 2004 Elsevier B.V. All rights reserved.
