In order to get more clean energy, many countries around the world are vigorously developing nuclear energy, but while developing nuclear energy, the treatment of nuclear waste has also been worrying the world, according to statistics, the world has produced more than 300,000 tons of nuclear reactor waste, their radioactivity needs thousands or even tens of thousands of years to fade, so much nuclear waste to deal with it? Recently China's new research and development of the Venus 2 reactor, to the world has brought a new direction, the full name of the Daystar 2 is lead bismuth-based zero-power reactor, is a reactor that produces almost no nuclear waste in operation, once it came out, it has aroused global concern, there are Western companies even door-to-door purchase, there are international experts believe that if China can eventually mature this technology, it is expected to completely solve the problem of nuclear waste pollution.

Nuclear power is the most promising technology to lead mankind out of the energy crisis, but until now nuclear power is still facing a serious problem, that is, a large number of nuclear waste pollution, nuclear reactors use nuclear fuel fission to generate electricity, and after the completion of nuclear fuel fission will produce nuclear waste containing a large amount of radioactive material, these nuclear waste human current technology can not be processed, can only seal them deep into the ground, waiting for thousands of years to let their radioactivity naturally fade, but with the increase in the number of nuclear power plants in the world, The amount of nuclear waste will also increase in the future, landfills will be filled sooner or later, and humans must consider the problem of disposing of nuclear waste in advance.

China's research and development of Daystar 2 is a special design reactor, its special feature is that it almost does not produce any nuclear waste when running, but also can convert the original non-radioactive material into radioactive materials for nuclear fuel, to achieve the self-added value of nuclear fuel, in other words, this reactor only needs to invest a small amount of nuclear raw materials after completion can be long-term operation, Daystar 2 not only will not discharge nuclear waste, but also can process nuclear fuel by itself, safety is greatly improved, but the cost is greatly reduced.
This kind of reactor strange performance has received global attention as soon as it is launched, many countries have asked China to disclose more technical details, but China has not yet agreed, the reason is that China itself has not completely broken through this technology, Daystar 2 although it has such a peculiar ability, but it is still a small test reactor, mainly used to verify whether this technology is feasible, can not be put into actual power generation, China must conduct more research on this technology, develop a more powerful reactor with practicality, It can be used to build nuclear power plants.

In fact, China's current technology in the nuclear reactor can be said to be the world's top, in addition to the development of Venus 2, China is currently developing a variety of different performance of the reactor, such as the world's first 4th generation reactor thorium-based molten salt reactor recently successfully achieved criticality, this reactor completely solves the existing reactor may occur nuclear accident risk, running almost no nuclear accident, at the same time smaller, can use cheaper nuclear fuel, is considered the direction of future nuclear power development.
In addition, there is a unique ball bed reactor, which also eliminates the risk of nuclear accidents, and can achieve in-operation material exchange, with the ability to operate in space, and the future human-developed nuclear-powered manned spacecraft is expected to use this reactor as power.
