Abstract
System for storing radioactive materials comprising: —a canister (4) containing radioactive waste; —a container (C), provided with a casing (1), a base (2) and a cover (3), and a passive helicoidal convection-based ventilation system provided with: lower air inlets (5); an area (6) of air circulation between the canister (4) and the inner surface of the container (C), and upper air outlets (7); the inlets (5) and outlets (7) have a decreasing variation of section in the direction of air circulation, are curved and facing an oblique direction with respect to the radial direction of the container, the air between said inlets (5) and outlets (7) describing an upward helicoidal path around the capsule or canister (4).
Claims7
A system for storing radioactive materials, comprising:
- a canister (4) containing radioactive waste;
- a container (C) provided with a casing (1), a base (2), and a cover (3), said container (C) delimiting a cavity for housing the canister (4);
- and a convection-based ventilation system provided with lower air inlets (5), an area (6) of upward air circulation defined between the canister (4) and the inner surface of the storage container, and upper air outlets (7);
- characterized in that the ventilation system consists of a passive helicoidal convection-based ventilation system, in which the inlets (5) and outlets (7) of the ventilation system have an outer mouth (51, 72) and an inner mouth (52, 71);
- in that at least the inlets have a decreasing variation in section in the direction of air circulation inside them, producing an increase in velocity, and a decrease in the pressure and temperature of air circulating therethrough;
- and in that said inlets (5) and outlets (7) are curved and facing an oblique direction with respect to the radial direction of the container, so that the air describes between the inlets (5) and the outlets (7) of an upward helicoidal path around the canister (4).
