Abstract
A thermal expansion-absorbing structure for piping, which is attached to a pipe end, is provided. A semicircular form of torus shell is joined to a cylindrical form of short double pipe to define together a U-shaped longitudinal section, which is deformed due to the expansion or contraction displacement of the pipe, thereby absorbing thermal expansion. This achieves a piping reduction, compactness of a reactor building and a reduction in the construction cost of a fast reactor plant, and ensures great safety.
