Abstract
The present invention provides a dry interim storage container for spent nuclear fuel, precisely a dry interim storage container that can be filled with spent nuclear fuel wherein the storage container space is also filled with metal particles. The dry storage container for spent nuclear fuel of the present invention is filled with particles in its empty space for the spent nuclear fuel, which is advantageous in cooling efficiency and maintenance cost, compared with the conventional storage method using gas.
Claims13
An interim storage container containing spent nuclear fuel, wherein the storage room for spent nuclear fuel is filled with metal particles.
An interim storage container for spent nuclear fuel comprising:
- a cylindrical body;
- an inner container having multiple storage rooms for spent nuclear fuel that is located in the inside of the main body;
- a cylindrical outer shell on the outside of the main body;
- a neutron shield to block the neutrons wherein the neutron shield is located between the main body and the outer shell;
- and
- a lid connected to the top of the main body, and
- wherein metal particles are contained in the storage rooms for spent nuclear fuel.
A method for cooling spent nuclear fuel during a period of interim storage, comprising the following steps:
- preparing an interim storage container for spent nuclear fuel composed of a cylindrical body;
- an inner container having multiple storage rooms for spent nuclear fuel that is located in the inside of the main body;
- a cylindrical outer shell on the outside of the main body;
- a neutron shield to block the neutrons wherein the neutron shield is located between the main body and the outer shell;
- and a lid connected to the top of the main body (step 1);
- and
- filling the empty sections in the storage room with metal particles before, during or after loading the spent nuclear fuel in the storage room of the container prepared in step 1 (step 2).
