Are there safer plants still, that focus on eliminating the daughter nuclei? I understood that one benefit of molten salt reactors is that the fission products were easier to process or burn. Edit: "MSRs enable cheaper closed nuclear fuel cycles, because they can operate with slow neutrons. Closed fuel cycles can reduce environmental impacts: chemical separation turns long-lived actinides into reactor fuel. Discharged wastes are mostly fission products with shorter half-lives. This can reduce the needed containment to 300 years versus the tens of thousands of years needed by light-water reactor spent fuel." https://en.wikipedia.org/wiki/Molten-salt_reactor https://en.wikipedia.org/wiki/Molten-salt_reactor
