Disposition of plutonium in a fusion driven subcritical assembly

Fusion is one of the options to destroy weapons and spent-fuel plutonium. A fusion reactor with high temperature helium cooled graphite blanket was investigated as a potential plutonium transmutation reactor. Neutronics performance and plutonium isotopic composition during the burn-up were calculated. In addition to the destruction of a large quantity of plutonium, the cost of electricity for the plutonium transmutation plant can be significantly lower than for a pure fusion power plant.
