More Information
Summary:The invention relates to the field of nuclear engineering, and more particularly to systems for the passive removal of heat from water-cooled, water-moderated reactors via a steam generator, and is intended for cooling a reactor by the natural circulation of a coolant (water) in a loop within the system. The technical result is the improved efficiency of a heat sink, the improved stability of the flow of coolant in the loop and, as a result, the improved operating reliability of the system. The present passive heat removal system comprises at least one loop for circulating a coolant (water), containing a steam generator and a sectional heat exchanger, the latter being disposed inside a cooling water reserve tank, higher than the steam generator, and being connected to the steam generator by a supply pipe and a discharge pipe. The heat exchanger comprises an upper collector and a lower collector, connected by heat exchange pipes; start valves with different flow areas are mounted on the discharge pipe. Furthermore, the heat exchanger is divided into parallel sections according to the condition L/D=20, where L is the length of half of a section (i.e. a half-section), and D is the inside diameter of a collector. Portions of the supply and discharge pipes of the circulation loop are configured in the form of a set of branched parallel pipes which are connected individually to each of the aforementioned sections of the heat exchanger.
