On the economic prospects of nuclear fusion with tokamaks
This paper describes a method of cost and construction energy estimation for tokamak fusion power stations conforming to the present stage of fusion development. The method is based on first-wall heat load constraints rather than beta limitations, which, however, might eventually be the more critical of the two. It is used to discuss the economic efficiency of pure fusion, with particular reference to the European study entitled "Environmental Impact and Economic Prospects of Nuclear Fusion". It is shown that the claims made therein for the economic prospects of pure fusion with tokamaks, on the basis of the present-day technology, do not stand up to critical examination. A fusion-fission hybrid, however, could afford better prospects. Support for the stated method is even derived when it is properly applied for cost estimation of advanced gas-cooled and Magnox reactors, the two very examples presented by the European study to "disprove"it.
