A Conceptual SCWR with Vertical Pressure Tubes

摘要：

A conceptual super critical water reactor (SCWR) with vertical pressure tube (PT) is presented in this paper. The PT has re-entry flow path. The low temperature downward flow between the tube and fuel assemblies protects the tube from contacting high temperature heated fluid in fuel subchannels. A gas cylinder is established out of the PT to prevent heat loss from coolant at operation. This gas insulation can be removed out to cool PTs with heavy water moderator during severe accident. It can prevent any fuel pellets melting with the cooling from moderator.
