NUCLEAR POWER IS RENEWABLE - MATHEMATICS AND LOGIC PROVE IT!
Breeder reactors: A renewable energy source (Am. J. Phys. 51(1), Jan. 1983)

Since energy sources derived from the sun are called “renewable,” that adjective apparently means that they will be available in undiminished quantity at present costs for as long as the current relationship between the sun and Earth persists, about 5 billion years. It is the purpose of this note to show that breeder reactors using nuclear fission fulfil this definition of a renewable energy source, and in fact can supply all the world’s energy needs at present costs for that time period......
.....We thus conclude that all the world’s energy requirements for the remaining 5 [billion] yr of existence of life on Earth could be provided by breeder reactors without the cost of electricity rising by as much as 1% due to fuel costs. This is consistent with the definition of a “renewable” energy source in the sense in which that term is generally used.
Nuclear fusion has been advertised as a method for “burning the seas.” We see that nuclear fission with breeder reactors is an alternative method for “burning the seas,” and it has the considerable advantage that the technology for doing it is in hand.
So, 29 years ago the calculations were done, to prove we had enough fertile isotopes of thorium and uranium to last 'forever'. All we need is a breeder reactor to deliver it safely and cheaply and everyone on Earth can have a decent standard of living, from a source which does not pollute the environment and degrade the chemistry of the atmosphere any further.
Foot-soldier-members of Greenpeace and Friends of the Earth:For goodness sake,use your common sense! You must stop listening to the deluded siren calls of your 'experts' and their Energy [R]evolution wish-list.
If you get behind LFTRs you have the experience and wherewithall to make it happen, and make it happen quickly!
