INSTALLATION FOR VERY LONG TERM STORAGE OF HEAT-GENERATING PRODUCTS SUCH AS NUCLEAR WASTE

摘要

A very long term storage installation for calorific products such as nuclear waste, comprising at least one closed cavity (10) receiving at least one container (14) for the containment of said products. In order to evacuate the heat emitted by the products thus stored, a jacket (26) is placed around each container (14), whereby a thermosiphon (24) is associated with said jacket and the cold source thereof consists of an air-cooled refrigerant condenser arranged above a slab (20) which closes the cavity towards the top. The container(14) is enclosed by the preferably interchangeable jacket (26) in a tight manner.
