Sciam: Fast neutron reactors and nuclear waste

A New Breed of Nuclear Reactors?: BLOG: SciAm Observations

Synopsis: Many are coming to believe that nuclear energy may be the most environmentally friendly way to generate electricity. Fast-neutron reactors could be fueled by what would otherwise be nuclear waste. But power utilities in the U.S. are not interested, in part because of the costs of developing a new generation of reactors.

"...the electrorefining method associated with fueling these reactors could also be used to process some of the existing mountains of radioactive fission waste."

"When the Energy Department decided to get rid of some surplus weapons-type plutonium by turning it into nuclear fuel, no utilities would take it, even at no charge."

Were the utilities concerned about accounting for the materials? The new reactor design would address such concerns, at least in part: "The actinides are kept mixed with the plutonium so it cannot be used directly in weapons."
