Development of Subchannel Code for Plate-Type Fuel Plus Verification

Abstract The fuel shape and flow path structure of the plate-type reactor are different from those conventional rod-bundle reactor, which leads to difference between thermal-hydraulic phenomenon thermal conduction in rod bundle assembly. Therefore, this thesis, subchannel analysis model code applied developed. calculation results compared with simulation FLUENT MATRA experimental heat transfer rectangular channel, so that is verified. This thesis first fully investigated friction models applicable channels, developed redistribution model. On basis existing two-fluid three-field code, software for plate type was comparison channel experiment shows can accurately predict coefficient under channel. verification MTR steady-state conditions codes show simulate phenomena Finally, according by characteristics analyzed, safety evaluated.
