Natura’s research reactor is designed to first prove the LFMSR concept at megawatt scale, then be converted to prove that MSR reactors can reprocess existing nuclear waste as a percentage of its fuel. Which means we could take all of the current stockpile of nuclear waste and re-burn it to the point that it’s 90% consumed (instead of 5% consumed today) and leave a waste product that decays to safe levels extremely quickly (tens of years).
