Embodiment Construction

[0041] See first figure 2 , The figure shows a manifold storage system 100 according to an embodiment of the present invention. Such as figure 2 As shown, the manifold storage system 100 is taken out of the ground. However, as will be described in detail below, the manifold storage system 100 is specifically designed to achieve dry storage of multiple sealed waste tanks containing spent nuclear fuel in an underground environment.

[0042] The manifold storage system 100 is a vertical, ventilated, dry spent fuel storage system, which is fully compatible with 100-ton and 125-ton transfer shielded tanks used for spent fuel waste tank transfer operations. The manifold storage system 100 can be modified / designed to be compatible with transfer shielding tanks of any size or form. The manifold storage system 100 is designed to replace an on-ground packaging structure (e.g. figure 1 The Independent Spent Fuel Storage Installation ("ISFSI") of the prior art (VVO1) shown in the prior art...

Abstract

A system and method for storing multiple canisters containing high level waste below grade that afford adequate ventilation of the spent fuel storage cavity. In one aspect, the invention is a system comprising: an air-intake shell forming a substantially vertical air- intake cavity; a plurality of storage shells, each storage shell forming a substantially vertical storage cavity; a hermetically sealed canister for holding high level waste positioned in one or more of the storage cavities so that a gap exists between the storage shell and the canister, the horizontal cross-section of each of the storage cavities accommodating no more than one canister; a removable lid positioned atop each of the storage shells so as to form a lid-to-shell interface, each lid containing an outlet vent forming passageways between an ambient environment and the storage cavity; and a network of pipes forming a passageway between a bottom portion of the intake cavity and a bottom portion of each of the storage cavities.

Description

[0001] Cross-references to related applications [0002] This application claims the benefits of U.S. Provisional Patent Application No. 60 / 652,363 filed on February 11, 2005, the entire content of which is incorporated herein by reference. Technical field [0003] The present invention generally relates to the field of storing high-level waste, and in particular, to a system and method for storing spent nuclear fuel in a vertical ventilation module, which adopts a passive convection cooling method. Background technique [0004] In the operation of a nuclear reactor, the fuel assembly is usually removed after its energy has been consumed to a predetermined level. When the fuel assembly is removed, this spent nuclear fuel is still highly radioactive and generates a lot of heat, so special care needs to be taken during its packaging, transportation, and storage. In order to protect the environment from radiation, the spent nuclear fuel is first placed in a transportable waste tank. ...
