A group of scientists say they are close to being able to build a system that breaks down nuclear waste into safer material using excess neutrons from a fusion reactor. (Via Instapundit.) No one has yet been able to build a fusion reactor that generates more power than it uses, but one isn’t be needed for the system to work.
Other technologies to dispose of most nuclear waste (mostly through re-use) have existed for decades, but were discontinued in the United States in 1976 due to concerns that they might lead to nuclear proliferation. I’d be interested to hear how the new technology compares.
