Neutron-induced fission of weapons plutonium in an accelerator/target/blanket system

PDF Version Also Available for Download.

Description

A proliferation-proof method for the disposition of weapons-grade plutonium using an intermediate-energy proton accelerator is presented in this paper. The method makes use of a spallation neutron source and a subcritical plutonium-loaded blanket assembly surrounding it. The neutron source consists of a heavy water-colled lead target, bombarded by a uniform-intensity 1 GeV, 100 mA proton beam. Plutonium is loaded in small graphite spheres (beads) which are enclosed in helium-colled zircalloy pressure tubes. A subcritical configuration of these tubes blankets the spallation neutron source. Uniformly-distributed erbium is used to control reactivity. The system, operating at constant power, is capable of burning ... continued below
