While they have improve the design with newer technologies, it still means that there is a much shorter learning curve to get personnel familiar with a new plant. In the U. There are the three types of very high temperature reactors thermal of the six preliminary designs that have been approved.
Because of the high temperatures, these reactors are also capable of producing hydrogen in addition to electricity. Also they are safer because the are built to withstand very high temperatures making accidents less likely as well as the gas being less dangerous than water-cooled plants where the water is able to absorb neutrons.
The fuel is incased into "pebbles" of tennis-ball sized graphite spheres see photo below which control the nuclear reactions making this a safer design. The Super Critical Water Reactor uses supercritical water, not a gas such as helium, as the moderating medium.
Similar in design to the older plants, but capable of handling high pressures and producing electricity cheaper and more efficiently. The Molten Salt Reactor uses molten salt as the main coolant.
Because of the molten salt, they are considered to be safer than current reactors. They are also smaller systems, so they are faster to build and get on line.
There is also no high pressured steam associated with these reactors, but there is very little experience in actual large-scale reactors numerous experimental models do work well. A single pellet contains as much energy as there is in one tonne of coal.
A typical reactor requires about 27 tonnes of fresh fuel each year. In contrast, a coal power station of a similar size would require more than two-and-a-half million tonnes of coal to produce as much electricity. Like any industry, the nuclear industry generates waste. However, unlike many industries, nuclear power generates very little of it — and fully contains and manages what it does produce. The vast majority of the waste from nuclear power plants is not very radioactive and for many decades has been responsibly managed and disposed of.
The used fuel which comes out of the reactor can be managed in different ways, including recycling for energy production or direct disposal. Electric vehicles. Start EV journey.
