Abstract

A mixing chamber structure for a prismatic high-temperature gas-cooled reactor, and a prismatic high-temperature gas-cooled reactor structure. The mixing chamber structure comprises an annular sidewall and a bottom plate (3); the annular sidewall is supported on the bottom plate (3) and sealedly connected to the bottom plate (3); the prismatic high-temperature gas-cooled reactor is supported on the annular sidewall and sealedly connected to the annular sidewall; the annular sidewall and the bottom plate (3) define a mixing chamber (5); the mixing chamber (5) is communicated with all coolant channels of the prismatic high-temperature gas-cooled reactor and used for mixing coolants flowing out of the coolant channels; an outlet flow channel (6) is further arranged on the annular sidewall and used for communicating the mixing chamber (5) with a reactor core outlet channel. The mixing chamber structure for a prismatic high-temperature gas-cooled reactor is capable of collecting, mixing, and transporting coolants, improving the uniformity of the coolants flowing out of a reactor core fuel zone, and improving the operating safety of the reactor.
