So long as they are built to the highest standards and operated by well trained staff, I see no reason why not.
Uranium
See www.world-nuclear.org and do your own research
Uranium fuel.
It is used for electricity in nuclear power plants == == Nuclear power is used to heat steam which then turns turbines, which generate electricity in nuclear power stations and also to provide propulsion and power on board nuclear submarines.
Fossil-fuel power stations, hydroelectric power stations and nuclear power stations.
Predominantly enriched uranium, but some reactors can use natural uranium.
Coal, natural gas, and nuclear mostly, very little oil now. Also some wind power.
cooling medium in nuclear power plants,and other power stations,melted liquid sodium is being used
Yes - some power stations located on the coast use sea water to cool the condensers. Examples of this include:Gladstone Power Station in Queensland, AustraliaKoeberg Nuclear Power Station in South Africa
there are pros and cons for using nuclear power (as with all power sources). pros of using nuclear power are: it can produce at lot more power than a combustion reaction can e.g burning coal, uranium and plutonium (used in the reactors of nuclear power stations) is fairly cheap. cons of using of using nuclear power include: the waste products of nuclear reactions are incredibly dangerous and take thousands of years to become un-reactive, nuclear power stations also have hefty maintenance requirements, cost a lot to build and don't last as long as more conventional power stations. So to address your question- people are divided over whether the pros of nuclear power outweigh the cons. it may be realistic to nuclear power, however it is very unlikely that it will be the world's main power source.
Certainly yes
Most nuclear power stations use uranium enriched to 3% uranium-235 isotope. The nuclear power stations in France include some reprocessed plutonium mixed with the enriched uranium. A small number of nuclear power stations were designed with fast neutron breeder reactors and used uranium enriched to as much as 93.7% uranium-235 isotope. As more of the uranium-238 (or thorium-232) in the breeding blanket was transmuted to fissionable plutonium (or uranium) isotopes, the breeding blanket material would be reprocessed and these fissionable isotopes would be used to replace the original spent uranium. But only a small number of such nuclear power stations were built and the system for reprocessing of the breeding blanket material was not set up.
