What are the dominant costs foreseen in a fusion power plant?
As you might expect in a magnetic confinement system, the largest cost item is anticipated to be the superconducting magnets. The next largest cost is anticipated to be the buildings needed to house the plant. These two items together are estimated to make up more than half of the cost of a fusion power plant. There is the expectation that the cost of superconducting magnets will reduce with time.
