Q. What do you mean by Fusion Reactors?
Ans.
It is pretty difficult to achieve fusion in the laboratory. A lot of energy is needed to initiate the fusion process and the reaction needs to proceed at a temperature of millions of degrees. Scientist are just now at the break-even point. The amount of energy needed to run the reactor is about the same as the energy removed.
Large-scale fusion reactors are the dream of many energy scientists. Fusion power plants would replace those now fueled by nuclear fission and fossil fuels. Because fusion power plants would not produce air pollutants they could minimize the environmental risks associated with the burning of fossil fuels and could substantially decrease demand for premium hydrocarbon fuels. Also, because fusion power plants would contain only small quantities of fuel at any time, they could eliminate the potential for runaway reactions that might lead to accidents. The development of low-activation materials or advanced fuel cycles for fusion reactors could make the amounts of high-level radioactive waste that result from fusion-produced energy far smaller than those produced by fission reactors, thus simplifying waste disposal problems.
Each element has a unique number of protons. This unique number is known as the element's atomic number . All atoms of a given element have the same atomic number. For example:
