CONTROL OF A FAST REACTOR BURNING URANIUM-PLUTONIUM OXIDE FUEL IN A SELF-ADJUSTABLE REGIME WITHOUT EXCESS REACTIVITY

摘要

Mathematical simulation is used to show that a reactor burning oxide fuel can be controlled in a self-adjustable neutron-nuclear regime, making it possible actually to operate without excess reactivity (ρ/β < 0.1). Waste-uranium carbide is used for control. When control is switched off, an appreciable power perturbation appears in apporximately 1 day.
