Title:
核融合炉のブランケットモジュール構造
Document Type and Number:
Japanese Patent JP3582013
Kind Code:
B2
Abstract:

To eliminate the requirement of executing slit working for reducing the electromagnetic force requiring an expensive technique of high-level such as blanket structure, to eliminate the requirement of adopting the first separated type wall structure requiring the complicated leg structure, to eliminate the requirement of using a large HIP device by only replacing for a damaged portion when damaged partially, and to eliminate, in addition thereto, the requirement of working a cooling passage for letting cooling water flow in a rear wall part.

In this blanket module structure for a nuclear fusion reactor, a shielding blanket module is finely divided in a toroidal direction into a large number of shielding facets, attaching legs protrude in both upper and lower end parts of a rear face in each poloidal direction, the large number of shielding facets are juxtaposed with a fixed dimension of space in the toroidal direction to be fixed by welding to protruded parts provided in both front face upper and lower end parts of a rear wall by the attaching legs, and a cavity is formed with respect to the rear wall. Each of the shielding facets comprises the first wall of a U-shape and a boxlike shielding body, the first wall is engagedly attached to the shielding body, and is integrated by HIP joining.
