Nuclear Power is a viable alternative power source to fossil-fuels since our demand for electricity is ever increasing and nuclear reactors can easily support the major demand as well as sustaining cost-efficiency of operation and maintenance of the plant. The fuel supplies are abundant and it is a low carbon energy source with low emissions.
Advances in technology are turning reactors from health and safety hazards into safe and efficient sources of electricity. True there are issues with waste disposal but again with future developments the waste can be re-used and the idea is that the final waste will be put into corrosion-free containers.
Ever since the sting of Chernobyl the public has always been extremely sceptical and doubtful about having a nuclear power plant in their back garden, but there have been major breakthroughs in design and even if a meltdown does occur and the reactor is destroyed a surrounding shell will prevent any radioactive material from being launched into the atmosphere.
For the foreseeable future at least I believe that nuclear power is a very good answer to our immense needs especially since the price per KW it produces is also low compared to any other power source.
