INTEGRATED SAFETY SYSTEM FOR REACTOR

Disclosed is an integrated safety system for reactor, formed at a reactor pool (10) in a reactor, and relating to the technical field of nuclear power. An accommodating cavity (11) is formed on the reactor pool (10), and the integrated safety system comprises at least one safety structure. Each safety structure comprises a residual heat export loop (100) and a first pressure relief loop (200), the residual heat export loop (100) comprising a heat exchange apparatus (110), a liquid supplementing apparatus (120), a water tank (130), and a cooling apparatus (140) disposed in the water tank (130). A heat exchange water inlet of the heat exchange apparatus (110) is connected to a liquid supplementing water outlet of the liquid supplementing apparatus (120). A heat exchange water outlet of the heat exchange apparatus (110) is connected to a cooling water inlet of the cooling apparatus (140). A cooling water outlet of the cooling apparatus (140) is connected to a liquid supplementing water inlet of the liquid supple
