International radiation damage tests in fusion materials: The oak ridge and beatrix exchange schemes

Abstract A number of RD — the Breeder Experiment Matrix (BEATRIX), concerning solid breeder material irradiation testing. Both schemes define about 20 tests each. The number of laboratories involved is 7 for the Oak Ridge and 11 for the BEATRIX test matrix. 10 test reactors in Canada, Japan, the United States, and Europe are used for the irradiations. The paper updates the present status of both schemes. An extensive list of publications is appended.
