France has not done well with nuclear power. Sure they get most of their electricity from nuclear power plants, however despite their lead in reprocessing France still has trouble with storage. While reprocessing allows spent fuel to be reused and shortens it's half-life doing so creates toxins and hotter fuel.
As far as building nuclear power plants go state planners on free market determines what gets built. CATO, that is the institute "dedicated to the principles of individual liberty, limited government, free markets and peace" printed the article "Hooked on Subsidies that was first published in the November 26, 2007 issue of "Forbes". The opening statements is "Why conservatives should join the left’s campaign against nuclear power." Further down it says:
"How do France (and India, China and Russia) build cost-effective nuclear power plants? They don’t. Governmental officials in those countries, not private investors, decide what is built. Nuclear power appeals to state planners, not market actors."
Now if private businesses want to build nuclear power plants they should get, and pay for, their own insurance. They would also have to finance the construction, not government. I might even invest in such a company that uses thorium as it's fuel. Provided the finances come out good.
