For those who would like further information, the August 2011 issue of POWER magazine has an excellent article by James M. Hylko about small modular fast-neutron reactors. Here is a link: http://www.powermag.com/issues/features/PRISM-A-Promising-Near-Term-Reactor-Option_3887.html
Instead of allowing emotional, political, technically ignorant opinions to steer policy, as in Japan and the United States, the engineers who run China (the Politburo is all engineers) are taking a prudent course in satisfying power demand. They know better than to buy into the delusion of renewable baseload generation, which will wreck the grid by forcing coal plants to go into cycling mode to accommodate intermittent wind and solar. The inescapable fact is that wind is available mostly at night, when demand is low and lots is available from the spinning reserve and hydro, so it can't be sold except through compulsion (renewable energy standards) and subsidies (feed in tariffs)..
Japan took another big step away from a nuclear power future, as its Cabinet approved a five-year science and technology plan that de-emphasizes next generation nuclear technologies – meant to be safe – in favor of renewables.
As the Mainichi Daily News notes, the Cabinet measure supports the position of Prime Minister Naoto Kan, who has advocated against nuclear following the March earthquake and tsunami that led to a meltdown at the Fukushima nuclear plant.
The five-year plan runs through March, 2016. The Cabinet was to have originally approved it last March, but postponed action until the Council for Science and Technology Policy could revise their draft recommendations following the disaster.
“As a result, references to promoting research and development on fast-breeder reactor fuel cycle, including the Monju prototype, and the next-generation light-water nuclear reactor for practical use, were omitted,” the paper reports.
Fast breeders and next-generation light-water reactors are two technologies that the nuclear industry say can improve safety and effectiveness. Monju is a troubled fast breeder test reactor in Japan.
While the Cabinet was in action, other wheels of Japanese government were also spinning. Bloomberg reports that, “Japan’s lower house of parliament is set to pass legislation to subsidize renewable energy amid a push to reduce dependence on nuclear power.” The subsidies include feed-in tariffs requiring utilities to buy electricity generated from solar, wind and geothermal sources.
Kan is expected to resign after the bill passes, as it would complete legislative goals he set before fulfilling a pledge to step down, Bloomberg notes.
Even though Japan and other countries like Germany and Italy are walking away from nuclear, many people believe the technology has a bright future.
In contrast to the sentiment in Japan, China last month connected a small test fast neutron reactor – similar to a fast breeder – to the grid.
Although China temporarily suspended approval for new nuclear plants following Fukushima, some industry observers believe it will construct as many as 100 nuclear reactors over the next 20 years. Given that the world has about 440 reactors today, that would spell decent growth for the nuclear industry.
