Creators

Description

Purpose: To improve the earthquake proof property of a pressure vessel and increase the degree of freedom of the pipeline of each circulation pipe system, thereby to improve the safety of the reactor. Constitution: A container having a containment liner and a pressure vessel holder concurrently used as a heat shielding wall are provided concentrically on the foundation concrete, and a pressure vessel is deposited at the upper opening support portion of the pressure vessel holder. By the constitution as described above, the strength of the pressure vessel holder can be enhanced and the center of gravity of the pressure vessel is lowered to improve the earthquake-proof property of the vessel.
