Tokamak closure leaves a hole at centre

Article Abstract:

The US' largest experimental tokamak at Princeton Plasma Physics Laboratory in New Jersey will close down after 15 years of successful operation, leaving the laboratory with an uncertain future. A reorganization that may result in the layoff of as many as 200 of the laboratory's 500 staff members is scheduled in Jun 1997. The country's magnetic fusion community expects Princeton to continue to lead efforts in magnetic fusion research despite the shutdown of the Tokamak Fusion Test Reactor. Many plasma physicists, however, lament the closure, saying it will take decades to build a strong laboratory again.

Japan's tokamak success boosts its bid for reactor

Article Abstract:

An upgraded version of the JT-60 tokamak fusion reactor, Japan's JT-60U, has succeeded in its goal of obtaining energy output equal to the energy input. The achievement has boosted Japan's bid to host the International Thermonuclear Experimental Reactor (ITER). Japan has informally proposed to pay up to 70% of the total costs of $10 billion of the ITER if it is allowed to host the reactor at one of its three locations. However, detractors feel that fundamental restructuring of the project is required before research work and location are discussed.

A steady course towards the next tokamak

Article Abstract:

The Japan Atomic Energy Research Institute (JAERI) researchers has started designing a steady-state tokamak fusion reactor to replace the JT-60 tokamak and to keep Japan at the forefront of fusion research. JAERI wants to build a tokamak capable of maintaining a heated deuterium-deuterium plasma for 100 to 1,000 seconds, far longer than existing tokamaks can do. However, JAERI's project may not get government approval if it conflicts with Japan's participation in the International Thermonuclear Experimental Reactor.
