China makes nuclear power breakthrough
BEIJING — China said Friday it had hooked its first so-called "fourth generation" nuclear reactor to the grid, a breakthrough that could eventually reduce its reliance on uranium imports
The experimental fast-neutron reactor is the result of more than 20 years of research and could also help minimise radioactive waste from nuclear energy, the state-run China Institute of Atomic Energy (CIAE) said.
China is the ninth country to develop a fast-neutron reactor, which uses uranium 60 times more efficiently than a normal reactor, helping the country to reduce its reliance on imports of the mineral.
Beijing has stepped up investment in nuclear power in an effort to slash its world-leading carbon emissions and scale down the country's heavy reliance on coal, which accounts for 70 percent of its energy needs.
But China's uranium reserves are limited, and it will have to import increasingly large amounts as its civilian nuclear programme gathers speed.
China -- the world's second largest economy -- currently has 14 nuclear reactors and is building more than two dozen others. It aims to get 15 percent of its power from renewable sources by 2020.
According to the World Nuclear Association, it aims to increase nuclear power capacity to 80 gigawatts by 2020 from 10.8 gigawatts in 2010.
The fourth-generation reactor, located just outside Beijing, has a capacity of just 20 megawatts. Other recently launched nuclear reactors in China had a capacity of more than one gigawatt, or 1,000 megawatts.
The latest technological step comes after China succeeded in reprocessing spent nuclear fuel in an experimental reactor in the northwestern province of Gansu in January.
Authorities said this would help extend the lifespan of proven uranium deposits to 3,000 years from the current forecast of 50-70 years.
Beijing has also pledged to improve emergency procedures and construction standards at its nuclear power plants, after Japan's devastating earthquake and ensuing tsunami triggered an atomic crisis.

The high-speed rail crash, in which at least 40 people died, was a blow to a gigantic project which, like China's nuclear strike force, is linked to the Communist party's prestige. It prompted open argument over a rush to development that many Chinese
The Russian region of Chelyabinsk, blighted by decades of nuclear waste dumping and accidents, has embarked on a controversial campaign to clean up its image on the internet. By Andrew Osborn Here is a list of the ten most polluted places in the world.
Russia & China are nowhere near and making no moves in that direction, and Iran, North Korea etc. won't be capable for many many decades, if ever. Since Trident will never be used against the USA, it is clearly a waste of money. If we need a nuclear
China takes another nuclear step - UraniumBlog
China continues to push the envelope in the nuclear space.
Officials said Friday it had connected its first so-called "fourth generation" nuclear reactor to the grid, a breakthrough that could eventually reduce its reliance on uranium imports, according to an AFP story .
Fourth generation here means a fast-neutron reactor, a result of two decades of research. It apparently uses uranium 60 times more efficiently than a normal reactor, helping the country to reduce its reliance on imports of the mineral.
China managed to reprocess spent nuclear fuel in an experimental reactor in the northwestern province of Gansu in January. This fourth generation breakthrough will help extend the lifespan of proven uranium deposits to 3,000 years from the current forecast of 50 to 70 years, Beijing said.
If successful, it could also help minimize radioactive waste from nuclear energy, the state-run China Institute of Atomic Energy (CIAE) said.
The government is pushing ahead with investment in nuclear power to reduce its reliance on coal-based power plants, which accounts for 70% of its energy needs. The rule of anecdotal thumb is that a new coal-fired plant goes into operation every day in China.
While uranium could prove to be the salve to its energy needs, the country’s reserves are limited, meaning more and more of the yellow cake will have to be imported as its civilian nuclear program is ramped up.
