Reactor radiation affects the chemical and physical properties of materials. These changes can be very drastic in certain cases. Special test reactors have therefore been built since the 1950s. Specific skills were developed to expose materials specimens to the precise irradiation conditions required. Materials testing reactors are those research reactor facilities which are designed and operated predominantly for studies into radiation damage. About a dozen plants in European Community Member States and in the U.S. can be identified in this category, with 5 to 100 MW fission power and neutron fluxes between 5 x 1.0 E13 and 1.0 E15 /cm2s. The paper elaborates common aspects of development, utilisation and future prospects of U.S and EC materials testing reactors and indicates the most significant differences.
