d-d Compact reversed field pinch reactor technology assessment

A quantitative comparison of the technology requirements, safety performance, and cost of a d-d compact reversed-field pinch reactor (CRFPR) relative to a d-t/CRFPR has been performed. The first wall/blanket and energy-recovery cycle for the d-d reactor is simpler and more efficient than the d-t reactor. In other technology areas (such as magnets and vacuum systems) d-d requirements are not significantly different than the d-t reactor. Tritium technology for processing the plasma exhaust is required for d-d reactors, but no tritium containment around the blanket or heat transport system is needed. Safety analysis shows similar consequences for the release of activated corrosion products or activated first wall/blanket structure. Consequences of all postulated d-d accidents for tritium releases are significantly smaller than those from the d-t reactor. Cost studies have been performed for a series of d-d reactors and compared with a d-t reactor
