The FUSECRAC code, a modification of the CRAC code, was developed to estimate public health effects from released fusion radioactivity both for safety studies and for comparison of the hazards associated with candidate structural materials. This paper summarizes the key motivations, problems, and results of the FUSECRAC comparison. The evolving CRAC code is a product of the Reactor Safety Study and represents the state of the art in fission accident consequence assessments. It was found that potential public health effects from accidental releases of 316 SS are two orders of magnitude higher than from V-15Cr-5Ti or TZM per unit volume of activated first wall released. The probabilities for releases among these materials were not addressed here.
