Abstract
An apparatus for promoting intermixing of heated fluid streams within a nuclear reactor vessel is implemented in such structural configuration and disposition as to be capable of not only promoting uniform temperature distribution of a heated fluid stream flowing into an outlet nozzle but also reducing flow resistance which the heated fluid encounters within a upper plenum of the reactor vessel. The apparatus is disposed within a upper plenum (,) defined within a nuclear reactor vessel (,) of a nuclear reactor above a core having a low temperature region (a) and a high temperature region (d) where a heated fluid flows at a low temperature and a high temperature, respectively. The upper plenum (,) is hydraulically communicated to outlet nozzles (,) installed at a side wall of the nuclear reactor vessel (,). The apparatus includes heated fluid guide members each having a predetermined short length and installed within the upper plenum (,) for guiding a heated fluid (b′) flowing out from the low temperature region of the reactor core to the vicinity of the outlet nozzle (,).
