Beschreibung
Zusammenfassung:	Disclosed is a combined active and passive secondary-side reactor core heat removal apparatus, comprising an auxiliary water supply system and a secondary-side passive afterheat discharge system, wherein the auxiliary water supply system comprises two redundant water supply series, one end of each water supply series being connected to an auxiliary water supply tank (6), and the other end being connected to a main water supply pipe (10) of a steam generator (9); and the secondary-side passive afterheat discharge system comprises several passive afterheat discharge series, each passive afterheat discharge series comprising a passive afterheat discharge cooler (14) arranged in an emergency cooling water tank (13), the upstream steam pipeline thereof being connected to a main steam pipe (11) of the steam generator, the downstream condensed water pipeline thereof being connected to the main water supply pipe (10) of the steam generator, and a passive supplementary water tank (12) further being provided between the upstream steam pipeline and the downstream condensed water pipeline of the passive afterheat discharge cooler. The apparatus can ensure that heat from the reactor core can be removed in the long-term in an emergency situation, alleviating serious consequences from an emergency.
