Abstract
One-time deep burnup of actinides (up to burnup >90% h.a.) followed by burial in geological formations without reprocessing is of great interest. In this paper, a method is proposed for deep burnup of americium and neptunium in special assemblies, containing actinides in an inert (stone-like) matrix and a strong moderator (zirconium hydride). Placing ∼130 such assemblies into a BN-800 core with oxide fuel permits 90–95% h.a. burnup in a realistic time – 2–3 runs (2.5–3.5 yr). Such a reactor permits utilizing up to 110 kg of americium and neptunium per year.
