During the last 10 years, WSI has developed a costing model in collaboration with Decysive Systems and most recently with Bechtel for the costing of most of the major fusion subsystems. We have worked under contract with ARPA-E to produce the cost analysis for 4 of the ALPHA program fusion concepts.
