Passive cooling system for liquid metal cooled nuclear reactor.

摘要

A liquid metal cooled nuclear reactor (10) having a passive cooling system for removing residual heat resulting for fuel decay during reactor shutdown, or heat produced during a mishap. The reactor system is enhanced with sealing means (48) for excluding external air from contact with the liquid metal coolant (20) leaking from the reactor vessel during an accident. The invention also includes a silo structure (24) which resists attack by leaking liquid metal coolant, and an added unique cooling means.
