Fission reactor sources for fusion materials testing

A comprehensive survey of fission reactors for potential application as sources for testing fusion reactor materials has been performed in connection with a much larger study for the development of a fusion reactor materials data base. A range of experimental reactors, both in this country and abroad, were surveyed to ascertain if they could be used to perform irradiation of three alloys (HT-9, PCA, and V-15Cr-5Ti) of high interest for fusion reactor construction. In addition, a selected group of breeder materials were identified for inclusion in the fission reactor testing. The study included implications for subcomponent testing since the primary goal of the larger program was to identify a series of small scale tests where interactive materials properties effects could be studied. The conclusion of this study is that fission reactor sources are necessary for fusion reactor materials testing, and that such sources are presently available
