Isotopically tailored HT-9 Steel for radioactive waste management

The Mirror Advanced Reactor Study (MARS) has developed the design of a first-generation tandem mirror reactor for commercial electric power applications. The goals for the MARS design include physics, technology, economics, safety and environmental compatibility of the reactor; we desired to minimize the volume of material that must be eventually disposed of as radioactive waste and to maximize the fraction of waste suitable for near-surface burial. These desires are somewhat conflicting because minimizing the volume of material is accomplished by increasing its life in the reactor which raises the radioactivity level. There are several questions that must be answered to address long term waste management. These are: What regulations govern disposal of radioactive waste from fusion. What methods can be used to affect the waste rating of a material. What is the cost of affecting the waste rating. The first question relates to governmental regulation. The authors have assumed that the rules for fission waste, as delineated in 10CFR61, could be applied to fusion
