SYSTEM FOR STORAGE AND TRANSPORTATION OF SPENT NUCLEAR FUEL

摘要

A concrete storage module (26) is adapted to slideably receive a cylindrical canister assembly (12) therein. Heat dissipation fins (62) and a tubular heat shield (96) are disposed within the module to help dissipate heat emitted from the nuclear fuel assemblies stored in the canister to air flowing through the module. The canister assembly (12) is composed of a basket assembly (70) constructed from multi-layer structural plates disposed in cross-cross or egg carton configuration. A single port tool (106) is provided for draining water from the canister (12) and replacing the drain water with make-up gas. The single port tool is mounted in the cover (100) of the canister and is in fluid flow communication with the interior of the canister.

主权项

1. A storage module for storing canisters containing nuclear fuel assemblies, said storage module comprising:
concrete bottom, side and top walls; said module configured for airflow through the module by natural convection to dissipate the heat emitted from the nuclear fuel assemblies; at least one heat transfer structure disposed within the module and positioned to transfer heat from the canister to the air flowing through the module; and at least one heat shield disposed in the module to shield the interior of the module from the heat emitted from the nuclear fuel assemblies.
