The invention discloses a leakage detection method for a nuclear island emergency raw water system. In the leakage detection process of the nuclear island emergency water generation system, on the premise that it is ensured that a leakage column meets the leakage detection condition, all water columns formed at the tail end of a vacuum pipe section serve as natural isolation media, and therefore when tracer gas is inflated through an exhaust valve on the vacuum pipe section, the water columns can serve as the pressure bearing boundary of the pressure of the tracer gas.
