Abstract

The present invention relates to reactor design technology, and more particularly, to a combined active and passive secondary-side reactor core heat removal apparatus. The said apparatus comprises an active subsystem and a secondary-side passive residual heat removal system, wherein the active subsystem comprises two redundant water supply trains, each of which is connected to an auxiliary feedwater tank (6) at one end and to a main feedwater piping (10) of a steam generator at the other end; the secondary-side passive residual heat removal system comprises a plurality of passive residual heat removal trains, each of which comprises a passive residual heat removal cooler (14) disposed in an emergency cooling water tank (13), an upstream steam line of the passive residual heat removal cooler (14) is connected to a main steam piping (11) of the steam generator (9), a downstream condensate line of the passive residual heat removal cooler (14) is connected to a main feedwater piping (10) of the steam generator (9), a passive make-up water tank (12) is disposed between the upstream steam line and the downstream condensate line of the passive residual heat removal cooler (14). The present invention allows long-term removal of heat from cores under emergency conditions thereby mitigating the consequence of a severe accident. (Fig. 2)
