... Within this time frame, it may be expected that further confirmatory results will be obtained from similar large Tokamak experiments being planned in Europe, the Soviet Union, and Japan. It may be of value when trying to form some outside judgment on the progress and rate of progress in fusion reactor development to note that the PLT, ORMAK Upgrade, PDX, Doublet III, and TFTR devices mentioned above are physics experiments.

... We note again that while scientific feasibility may be demonstrated within the next several years in one or more devices, any reactor based on these results may turn out to be far from optimum in terms of the performance attainable eventually in practical fusion reactors. However, demonstration of scientific feasibility, besides providing a test bed for the performance of relevant physics experiments, should provide a realistic basis for further optimization of designs leading to economically attractive reactors.
