Anyhow we can shift to surgenerators and use Uranium 238 or Thorium 232 (which are available in quantities that could last us thousands of years).

(cf. Superphénix, which was abandoned due to countless minor technical flaws, led mass opinion to accept that surgeneration was impossible ... people have forgetten that Superpéhix was only a prototype, which actually produced electricity for years before being shut down, not the least because the Greens came to power with the Socialists and said "schtoppen zi").
