William Hannum, Gerald Marsh, George Stanford -As today’s thermal reactors reach the end of their lifetimes, they could be replaced by fast reactors. Should that occur, there would be no need to mine any more uranium ore for centuries and no further requirement, ever, for uranium enrichment. For the very long term, recycling the fuel of fast reactors would be so efficient that currently available uranium supplies could last indefinitely.
Charles Till and Yoon Chang describe the evolution of the Liquid Metal Reactor, the development of the Integral Fast Reactor. This is a key step to providing plentiful energy for the world for a very long time.
