The cost of nuclear power is tribute paid to the global evil empire that opposes anything that threatens its ability to rule the world, the British Empire! A country that has nuclear power is a country that is energy independent and has a basis for advanced industry and medicine.
To lower the cost of nuclear power 10-fold in the short term, exit NATO and exit Five Eyes, and expose the British imperial anti-science frauds, beginning with Isaac Newton and Bertrand Russell. Without the irrational fear of radioactive materials and nuclear accidents that these frauds create, by depriving the population of understanding of the method of scientific investigation that has proven fruitful throughout human history, nuclear power plants would be the cheapest plants you could build per gigawatt of actual capacity, if fuel and maintenance costs for the first 10 years are considered. In time, with experience, it would be the cheapest to build, period.
An honest evaluation of the risk would open the door to the use of molten salt breeder reactors, molten lead breeder reactors, and the very high temperature gas-cooled pebble bed reactors, all of which are far safer than the best light water reactor, which already has an excellent safety record (but irrational fears restrict us to already-approved designs, designs approved back in the days when anti-nuclear paranoia was less psychotic, and make the process of approving new designs, however meritorious, prohibitively expensive). The breeder reactors offer the advantage of using all isotopes of uranium, plutonium, transuranics and thorium as fuel, and the pebble bed provides the highest temperature industrial process heat possible by any method not requiring the production of electricity first, with the possible exception of using thermite. Fast neutron breeder reactors using the U238-Pu cycle can generate enough extra Pu to power the pebble bed.
