FRANCE: Doubts Rise Over the Great Nuclear Promise
By Julio Godoy
 
PARIS, Jul 12 (IPS) - The euphoria over a decision to base the 
International Thermonuclear Experimental Reactor (ITER) in France seems to 
be evaporating. What remains is a growing doubt over the feasibility and 
cost of the project.
 
The project seeks to introduce new nuclear technology. It will seek a 
nuclear fusion of two hydrogen isotopes (deuterium which exists abundantly 
in nature, and tritium, a synthetic isotope) to produce helium with massive 
release of energy to produce electricity.
 
The ITER is an international project co-financed by China, the European 
Union, Japan, Korea, Russia and the United States under the auspices of the 
International Atomic Energy Agency. It is scheduled to be operative by 2016.
 
An international commission announced last month that the ITER would be set 
up at the French nuclear research centre Cadarache in Provence, 900km south 
of Paris.
 
French President Jacques Chirac called the decision to base the project in 
France ”an enormous success” because the project ”opens the way for 
technology essential in the search for alternative energy sources to 
counter global warming.”
 
The daily Le Parisien greeted the announcement as ”good news for France, at 
last.” Most French newspapers welcomed the decision.
 
But scientists and environmental groups are warning that the ITER would 
drain resources that could fund the search for better alternative energy 
sources. The project itself, they say, brings no guarantee of success in 
the immediate future.
 
Former minister for science and technology Claude Allegre, also a renowned 
researcher in geochemistry, described the ITER as ”just another prestige 
project” with ”very few chances of success.”
 
The estimated 12 billion dollars needed for the project will drain 
resources from other research projects ”certainly more urgent than the 
ITER,” he said. Just the construction is expected to cost more than 5 
billion dollars. France has promised to pay half the cost.
 
The ITER at Cadarache will be a research reactor. If the technology proves 
promising, a first working thermonuclear reactor could get going some time 
after 2050.
 
The reactor will introduce brave new technology. Officials say the fusion 
at the plant would take place around 100 million degrees Celsius. The plant 
would seek to produce 500 megawatts (MW) of power.
 
The temperatures alone are a problem because no known material can resist 
such heat. ”The official announcements describe the ITER processes as 
putting the energy of the stars in a box,” says Sébastien Balibar, 
professor of nuclear physics at the prestigious Paris-based École Normale 
Superieure. ”The problem is, we do not know how to build the box.”
 
Balibar and his colleagues Yves Pomeau and Jacques Treiner said in a paper 
published last year in Le Monde that a thermonuclear reactor poses three 
technical problems: production of the elements to undergo fusion (deuterium 
and tritium), their resistance to fusion, and control of this reaction. The 
scientists said that the ITER project is only interested in the last, ''and 
ignores the other two, the solution of which, nevertheless, is essential.''
 
Edouard Brézin, president of the French Academy of Sciences, says 
expectations of the ITER are overly optimistic. ”We need to be extremely 
confident in scientific development to believe that the industrial use of 
nuclear fusion will be ready in less than 50 years,” Brézin told IPS.
 
Research in this technology should continue, he said, but ”fossil 
combustibles and global warming are urgent problems, and we do not have 50 
years to find solutions for them. We need urgent measures, and the ITER 
should not drain resources from this research.”
 
Stephane Lhomme from the anti-nuclear group Sortir du nucléaire ('Get rid 
of nuclear power') told IPS that the ITER represents a dangerous technology 
without a future.
 
It is probable that the ITER will never produce energy, Lhomme said. The 
French government had invested almost 9 billion dollars in the nuclear 
reactor Superphénix before deciding to close it down in 1998, he said. The 
Superphénix never generated a watt of power.
 
 
”The ITER will certainly be connected to the French electricity network, 
but only to get power for its functioning,” Lhomme said.
