Abstract
The present inventive concept provides a method for manufacturing a multi-layered nuclear fuel cladding pipe, comprising the steps of: providing a preliminary cladding pipe in which an inner pipe having a rod-shaped insertion body inserted thereinto is disposed in an outer pipe; reducing the diameter of the preliminary cladding pipe by applying pressure from the outside to the inner side of the preliminary cladding pipe; and removing the insertion body from the inner pipe by providing a force in the direction in which the insertion body extends, wherein the inner pipe and the outer pipe may be formed of different metals from each other.
Claims12
A method for manufacturing a multi-layered nuclear fuel cladding pipe, comprising:
- providing a preliminary cladding pipe in which an inner pipe, into which a rod-shaped insertion body is inserted, is disposed in an outer pipe;
- reducing a diameter of the preliminary cladding pipe by applying pressure from outside the preliminary cladding pipe to an inner side of the preliminary cladding pipe;
- and
- removing the insertion body from the inner pipe by providing a force in parallel to direction in which the insertion body extends,
- wherein the inner pipe and the outer pipe are formed of different metals from each other,
- wherein the reducing of the diameter of the preliminary cladding pipe comprises moving the preliminary cladding pipe between a plurality of rollers pairing up with each other, by arranging in a longitudinal direction of the preliminary cladding pipe a plurality of rolling units each comprising the plurality of rollers, and
- in the reducing of the diameter of the preliminary cladding pipe, the outer pipe and the inner pipe are tightly fixed to each other to manufacture the multi-layered nuclear fuel cladding pipe.
