One attractive feature of fast reactors is that they can produce more fuel than they consume, avoiding the issue of the limited supplies of the uranium used in conventional nuclear reactors.

This makes the nuclear waste coming out of fast reactors decay to natural radiation levels much faster than traditional nuclear waste.

Also, recycling nuclear fuel (as is often but not always called for in fast reactor fuel cycles) brings up proliferation concerns that inspired the Jimmy Carter administration to cancel a large US effort to develop a fast - reactor system.

Also, one of the only ways to really destroy nuclear waste is to burn it in fast reactors.

«Unlike today's nuclear reactor, the IFR [integral fast reactor] can generate unlimited amounts of inexpensive clean power for hundreds of thousands of years... It provides an excellent solution for what to do with our nuclear waste because it can use our existing nuclear waste for fuel and it is significantly more proliferation - resistant than other methods of dealing with nuclear waste...
