1.   The reactor is widely regarded as the last step before design of commercial fusion reactors.

2.   They will also have developed a new technique for controlling reactions within a fusion reactor.

3.   Fusion researchers long have contended that fusion reactors would be cheaper than nuclear reactors and would produce substantially less radioactive waste.

4.   He spent millions on an unsuccessful attempt to develop small nuclear fusion reactors, financing a team led by Robert W. Bussard, a nuclear scientist.

5.   His plasma waves figured in various proposals for fusion reactors.

6.   Huge pulses of fusion power have already been generated by experimental fusion reactors in the United States and Europe.

7.   Insufficient financial support has thrown the future of a proposed international fusion reactor so much in doubt that the project could be killed by January.

8.   No other tokamak has yet produced surplus power, though the JET fusion reactor at Culham in Oxfordshire has come close.

9.   No longer are there target dates for completing a commercial fusion power reactor, nor even plans that go beyond the pursuit of relatively narrow and modest research goals.

10.   Some scientists and engineers have argued that fusion energy is inherently impractical because a fusion reactor costing billions of dollars would quickly wear out.
