American engineers have developed a microreactor for a nuclear power plant in which all hazardous waste is disposed of with salts; the device not only protects against the effects of the explosion, but also allows the use of useful elements in industrial production.
Nuclear elements can emit heat or radiation for hundreds of thousands of years while they slowly cool down, so they're so dangerous, in traditional nuclear reactors, there's a constant flow of water through the rods that protects them from overheating, but a shutdown of the cooling system can disrupt the reactor and cause an explosion like that in Chernobyl.
In the new system, all waste is stored in molten salt. It has an extremely high melting temperature of about 550 °C and is explained by scientists. In this environment, radioactive elements cool very quickly, and as soon as salt crystallizes, the heat emitted is absorbed, thus eliminating the risk of melting the nuclear power plant.
Another advantage of the salt melt reactor is that it can eliminate hazardous nuclear waste. Reaction products are contained in salt, and there is no need to store them elsewhere. Moreover, many of these products are valuable and can be separated from salt and sold.
For example, salt can provide a molybden-99 expensive element that is used in medical visualization and scanning procedures, and in the process of operation of the reactor, cobalt-60, gold, platinum, neodial and many other elements are stored in waste.
A typical nuclear power plant occupies giant squares, most of which are needed to reduce radiation risk, and a reactor created by scientists can be located 1.2 metres by 2.1 metres, and will be sufficient to provide electricity to about a thousand homes.
