The USA are to participate in the negotiations on construction
and operation of the ITER international experimental fusion reactor, as
announced by Energy Secretary Spencer Abraham in Princeton on 30 January.
He rates the research device as an important element „to feed the energy
needs of growing economies around the world“. The USA wants to contribute
about 10 per cent of the total cost of the project – part of this by
producing individual components of the device – and be accordingly
involved in management and research.
In a recent letter to the ITER partners China also offered to cover about
10 per cent of the budget, as reported in „NATURE“ on 23. January
2003: „China intends to make a major contribution to the project in
the form of material or funding“, stated China’s Minister of Science,
Xu Gusnhua.
The ITER experimental reactor is the next major step in international fusion
research, whose goal is to develop a power plant which, like the sun, will
generate energy from fusion of atomic nuclei.
To ignite the fusion fire, the hydrogen plasma fuel has to be confined in
magnetic fields and heated to very high temperatures. The purpose of ITER,
which has been in preparation since 1988 as an international cooperation
between European, Japanese, Russian, and US research scientists, is to demonstrate
the physical and technical feasibility of fusion. With a fusion power of
500 megawatts, the device is to produce a burning, energy-supplying plasma
for the first time. The construction cost is estimated at about four billion
euros.
In 1998 the United States withdrew from the project. The final construction
plans were completed by the other partners in July 2001; essential components
of the device have been built as prototypes and tested. Sites for the device
have been offered by France, Spain, Canada, and Japan. This decision of
the USA to rejoin the international venture was prompted by several scientific
expertises (see IPP Press Release
9/02) confirming
ITER as the appropriate next step in fusion research.
The negotiations conducted since November 2001 by the international partners,
Europe, Canada, Japan, and the Russian Federation, will now involve the
USA and China as well. To be regulated are the legal entity of the international
project, its organisation, the site, and the allocation of costs and production
contracts among the partners. The appropriate agreement can possibly be
drawn up this year already and submitted to the governments of the partners.
