Abstract

A principal goal of the US fusion materials program is to develop new materials so as to minimize the activation of future fusion reactor structures. The objective is to improve the environmental acceptability of fusion power. The current guideline is that structural materials should meet the requirements of 10CFR61 for near-surface burial as radioactive waste. Analyses of the bases for the concentration limits in 10CFR61, and the trend toward conservatism in radioactive waste disposal, strongly suggest that the criteria in 10CFR61 will not be conservative when applied to fusion reactor waste materials. It is recommended that emphasis be placed on developing a strategy for the controlled recycling of radioactive materials within the nuclear industry. It is also recommended that a systematic sampling of the public perception of fusion power be initiated.
