Or is it too dangerous to have any C around? Can you further explain the potential benefit of Thorium? Finally, I have a question about the radiation shielding layers... if the reactor is operating between 400 and 600C optimally, how can the lead shielding remain solid? or if the borated water solution is used, won't that vaporize? thanks to you all for your insightful contributions and engagement. > * * >
