Scientists are developing a new generation of nuclear reactors

Climatologists perhaps right in saying that the world need nuclear energy, if the world wants one day to slow down or completely stop climate change and global warming. However, while there is a risk of disasters – a tragic example of that occurred in March 2011, is Fukushima . It will be difficult to convince people that nuclear energy is not only able to destroy all life, but also to save .

Portal Our World writes that, according to scientists, this dilemma can be solved by the construction of nuclear reactors of the new generation. They are unlike those currently used, will be substantially less. And due to the small size of their construction will be easier and faster. In addition, they will be much safer, and partly due to the fact that they will work underground. Experts believe that, unlike the current, new reactors will be less vulnerable to potential terrorist attacks and natural disasters.

Another interesting feature of the new compact reactors is that they will be modular, ie not built as a single structure, and as a designer. Work in this case will only need to collect all the pieces together. At the same time the largest of these reactors will be able to generate a little less than 300 megawatts of power, and the smallest of them and even less – about 25 megawatts. In fact these plants will produce only five times more energy than wind turbines.

Sounds crazy yet, but among scientists there are already those who believe that such compact modular reactors could one day efficacy and safety be on par with renewable energy sources and to help people living in the most remote parts, reduce dependence or even refuse to diesel generator sets. Scientists attribute this to the fact that the principle of modular reactors allow people to adjust the generated power, adjust it with their needs and at the same time they will work on the basis of green (safe) sources.

Such reactors have to refuel only once in ten years, and thanks to the new cooling system, increase the autonomy of their work. Reactors will not require daily checks. All the necessary inspection will be held once a week.

To date, experts around the world are developing about 20 different concepts for new reactors. World Association of Nuclear Operators believes that by 2030 the world will appear about 96 such facilities. Among all the countries around the world the U.S. marked one of the most active in the study of this question. Over the past two years the country has invested 452 million dollars in the company NuScale and Gen4 Energy, working on two different designs of compact nuclear reactors.
