Lay it out for me then. There are roughly 40,000t of accessible fissile material (U235 and Pu239) on earth. You need about 3.5t to run a GW of PWR for 6 years

Lay it out for me then. There are roughly 40,000t of accessible fissile material (U235 and Pu239) on earth. You need about 3.5t to run a GW of PWR for 6 years. This generates up to half a tonne of Pu239. Primary energy is about 17TW. You need about 12TWe to meet this. We'll assume 5TW of heat needs can be met with a geographically isolated low head steam generator. Assume your reactors are free and all mining capacity grows at 100% p.a. from the current ~200t of U235 that isn't in inaccessible tails per year and reactors are constructed in record times of 5 years. Make it make sense. Provide a net zero solution for 2050.
