Abstract
Based on the previously created model of a promising passive heat removal system directly from the primary circuit of the WWER-1000 reactors, based on the use of ordinary two-phase thermosiphons (OTPT), which was used for calculations using the RELAP5/Mod3.x software, a completely similar calculation model was built for the KORSAR program. The calculated results of the operation and efficiency of the PHRS RP channel obtained using both models are compared. It is established that, despite the differences in the design parameters within the actual OTPT, the design characteristics of the PHRS RP channel as a whole, obtained using both PS, differ insignificantly. This is explained, in particular, by the damping properties of a closed two-phase intermediate circuit, which performs heat transfer from the condensing section of the OTPT to the heat exchanger – condenser of the intermediate circuit, which, in turn, removes heat to the end sink – atmospheric air or water outside the containment. Nevertheless, the results of the work performed allow us to conclude that a series of experimental studies of heat and mass transfer processes inside the OTPT on the simplest stands, followed by a comparison of experimental data with calculated results obtained using both of the above-mentioned programs.
