摘要：An apparatus and a method for detecting a leakage of heavy water in a nuclear

reactor system includes: a diode laser that generates a laser beam and injects thegenerated laser beam to a test sample placed in a light absorption cell; the lightabsorption cell accommodates a gathered test sample therein; a vacuum pump adjusts adegree of vacuum in the light absorption cell; a test sample introduction unit gathers anair test sample from a location with a high possibility of a leakage of heavy water or alight water test sample from a secondary side of a steam generator and transfers thesample to the light absorption cell; an optical detector detects the laser beam which haspassed through the light absorption cell; and a microprocessor controls the operation ofthe diode laser, the light absorption cell, the vacuum pump, the test sample introductionunit, and the optical detector, receives a detect signal from the optical detector, andanalyzes an absorption spectrum signal.
