Yes, a LFTR needs a sort of spark plug, a strong source of neutrons to get the cycle going. Only about 1000 pounds of Uranium enriched to 20% is required (90% would be needed for a bomb). After that initial start Uranium is never needed again, just more thorium. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
