Chinese fast reactor nuclear power plant will likely supply electricity for Chinese electricity market 30 years later, said Wang Naiyan, the academician of Chinese Academy of Sciences and director of China Institute of Atomic Energy, on June 7th in Beijing.
China will strive hard to make commercial use of its fast reactor nuclear system in around 2035 and make it the main source of nuclear power after 2050, according to the Mr. Wang's academic report delivered at the 13th China Science Institute Academic Conference.
"Nuclear power plant is very safe. Due to the advancement of nuclear technologies, tragedies like Chernobyl nuclear disaster will not happen again. While upgrading heating reactor nuclear technologies, we should make great efforts to develop fast reactor nuclear technologies which have a bight future," said he.
Mr. Wang remarked that fast reactor nuclear system not only involves the faster reactor nuclear technologies, but also fuel-short after-treatment, fast reactor fuel, as well as other complicated technical and engineering issues. It will be an arduous task for China.
Sustainability of nuclear energy depends on the full use of uranium resources and minimization of nuclear wastes. Nowadays, however, just less than 1% of the uranium resources are fully used in the heating reactor nuclear power plants across the world. Not until most of uranium-238 are burnt while circulating in fast reactor is the utilization of nuclear resources optimized.
Mr. Wang said, "The known regular nuclear resources can last for several thousand years if we adopt fast reactor and closed nuclear fuel cycle technologies." "The researches on nuclear fuel cycle for fast reactor are very difficult. But China has never done any kind of this research before. So we should bring up a technical scheme and an implementation plan for fast reactor nuclear fuel cycle research on the basis of learning from foreign experience," he added.
