Responding to current decision of Japanese
government that it would continue the project of nuclear recycling, Asahi
Shimbun delivered featuring story about development of fast-breeder reactors in
major countries in the world. As realizing how current situation is far from
aimed achievement, one can realize that nuclear recycling is nothing but a
dream. The article concluded that the effort of the government is not for
making that dream come true but to justify resuming nuclear reactors in a
number of nuclear power plants in Japan.
The article quoted the project in France,
which is the top runner of nuclear recycling. France started nuclear recycling
in 1960s with development of experimental reactor. It evolved to prototype
reactor called Phoenix and proven reactor called Super Phoenix. However, the
greatest inferiority of FBR was using sodium, which explosively reacts to
water, for cooling reactor. Super Phoenix suffered from major accident of
leaking sodium in 1987. There is no working FBR in France now.
Plutonium derived from used fuel in nuclear
power plants in France is reprocessed to mixed oxide fuel for plutonium-thermal
power generation. Annual consumption of MOX fuel amounts to 120 metric tons,
which cost is higher than other method of electric power generation. Although
France has a plan of developing proven reactor called ASTRID, the process still
remains on the desk.
United Kingdom also made attempt of nuclear
fuel recycling. But, it ended the project in 1994, seven years after major
accident in a prototype reactor, realizing nuclear fuel recycling was not
economically efficient. Because U.K. kept on reprocessing used nuclear fuel
afterward, it still possesses 100 metric tons of plutonium going nowhere.
United States is the first country that
retreated from nuclear fuel recycling. Shocked by Indian development of nuclear
weapon from technology for nuclear power generation, the administration led by
President Jimmy Carter delivered new policy freezing reprocessing that would
cause nuclear proliferation and postponing development of FBR. President Bill
Clinton decided research and development of nuclear fuel recycle and stopped
all experimental reactors.
Having seen how nuclear fuel recycling is
far from commercial level, optimism of Japanese government looks strange. While
it decided to dismantle FBR called Monju this year, it still promotes nuclear
fuel recycling to next level, building a proven reactor. Asahi questioned that
the reason why Japanese government insists on nuclear fuel recycle can be because
used nuclear fuel loses its place to go, if reprocessing plant stops working. The
paper requires the government to wake up.
