I kinda wish there was a NASA equivalent for nuclear that would be given 10s of billions of dollars per year to R&D safer, next gen nuclear power plants. The organization could build/run those plants around the world in order to provide less developed countries with power while preventing proliferation.

An international version of this was Oppenheimer's vision (both for peaceful nuclear applications and weapons) which he expressed in his personal writings and in the Acheson–Lilienthal report. It was not looked favorably on by most of the US government and was the first step to the eventual revocation of his security clearance and removal from any position of influence.
