Abstract [en]

Efficient recycle of high level waste in spent nuclear fuel decreases the time required to isolate residual waste by a factor of 100 and reduces the volume of the waste repository by a factor of 4-6. Technical approaches to accomplish this feat include fast neutron Generation IV reactors and accelerator driven systems. Here, I present a novel design of a very small, passively safe lead-cooled reactor with (Np,Am)N fuel, which is shown to achieve maximum possible efficiency in transmutation of long-lived high level waste, while producing a nuclear fuel that is difficult to use for weapons production. Using this reactor for waste management minimises costs for demonstrating closure of the nuclear fuel cycle.
