Abstract: A ventilated system for storing high level radioactive waste, environment, such as nuclear fuel, in a below-grade environment, in one embodiment, the invention is a ventilated system comprising an air-intake shell and a plurality of storage shells that are interconnected by a network of pipes configured to achieve double redundancy and/or improved air delivery. In another embodiment, the invention is a ventilated system that utilizes a mass of low level radioactive waste contained in a hermetically sealed enclosure cavity, the low level radioactive waste providing radiation shielding for high level radioactive waste stored in a storage cavity of said ventilated system.
