Abrégé

A health monitoring system and method for a sphere pipeline of an HTR-PM fuel unloading system. The monitoring system comprises a first non-shielding section transducer, a second non-shielding section transducer, a first shielding section transducer, a second shielding section transducer, and a multi-channel acoustic emission detector; the first non-shielding section transducer, the second non-shielding section transducer, the first shielding section transducer, and the second shielding section transducer are electrically connected to the multi-channel acoustic emission detector; the first non-shielding section transducer and the second non-shielding section transducer are respectively fixed on the upstream and downstream of a non-shielding section fuel unloading system pipeline fitting; and the first shielding section transducer and the second shielding section transducer are respectively fixed on the upstream and downstream of a fuel unloading system pipeline fitting. The monitoring system can continuously monitor the state of fuel spheres in a sphere pipeline of a fuel loading and unloading system for a long time, and can track and position the flow track of the fuel spheres.
