A MAJOR BREAKTHROUGH IN CHINA’S NUCLEAR TECHNOLOGY, URANIUM UTILIZATION WILL INCREASE 60 TIMES
Recently, Chinese scientists in nuclear research has made significant technological breakthrough to achieve nuclear power reactor uranium-plutonium fuel for combustion material recycling, and if we can achieve plutonium recycling in the dynamic heap, which means the size of our existing nuclear power , China has proven uranium resources can only be used from about 50 to 70 years into the year 3000 to spend enough.
Professional name of this technology is called "Power reactor spent fuel reprocessing technology," experts said the nuclear power generation by nuclear fission reactions that occur in nuclear reactors release energy, and coal-fired power stations to continue to increase as the maintenance of nuclear fuel can not be certain when power, they also need to be replaced, these are for down the nuclear fuel is called spent fuel assemblies, popular to say, spent fuel similar to the thermal power station in the "cinder", but it is definitely not cinder, it is the baby, because the world's only nuclear power technology under the nuclear fuel burned for about 3% to 4% to rated power can not sustain, while the nuclear fuel in the combustion process will produce new nuclear fuel.
This time need to be reprocessing nuclear fuel, which is the chemical process through a number of columns, the complete combustion of fuel for nuclear power plants do not produce nuclear fuel and the new extract, then the point of the fuel needed to make nuclear fuel elements. The principle sounds simple recycling operation is extremely difficult, how these have a strong nuclear radiation on human body parts were cut fatal injury, separation, extraction, purification, etc., each step is difficult, our scientists through 24 The study of trial and error finally broke a complete set of technical system. Entirely on their own country we design, self build, self-commissioning, independent research and development facilities, the last test was prepared by a qualified products of uranium and plutonium products, so it is a success.
In the international nuclear fuel inside the industry, China is a very few countries capable of forming one of the nuclear fuel cycle, so for the whole level of technology at the technical level of the existing right to speak, and even play a guiding role. Prior to France, Britain, Russia, Japan, India and other countries to grasp power reactor spent fuel reprocessing technology, and thus became the first of eight countries with fast reactor technology.
Introduction to fast reactor technology:
Fast neutron reactor (referred to as the fast reactor) is the world fourth-generation nuclear energy systems technology, and is currently running and is building the second generation, third generation nuclear power plants compared to the formation of closed nuclear fuel cycle, uranium resources can utilization rate to 60% or more (only 1% of existing nuclear power plant, which is enhanced 60 times.)
Increase the utilization, relatively depleted uranium has been mined value. On the world scale, recoverable uranium resources would thus increase thousands of times. The current proven reserves of natural uranium speculated that the use of fast reactors can make sustainable use of uranium resources in 3000 years.
