Method and device for storing the fuel elements irradiated or brules of the top plug pressurized or a boiling water

摘要

For storage purposes, the fuel elements located in appropriately shaped sleeves (4) are arranged vertically in a concrete chamber (1) and cooled with air. The concrete chamber has at least one horizontal grid plate (3) for accommodating the sleeves vertically, and is provided with supply-air and exhaust-air ducts (5, 6) which open into a common vent stack (7) having separate air guidance. Owing to the complete elimination of storage in water basins, the previously high consumption of cooling water and the environmental stress due to cooling towers are also eliminated, with the result that storage is simplified and reduced in cost.
