The paper introduces the pressure pulsation transducer at Tianwan Nuclear Power Station(TNPS), and summarizes the existing problem of using pressure pulsation transducer. The system operator put forward the optimization and modification,after the demonstration of Russian design manufacturer and the approval of the safety and importance reply from National Nuclear Safety Administration(NNSA), according to construction scheme and radiation protection scheme, the operator carry out the modification adding isolating valve and pulsation pipeline in outage at TNPS. The replacement of pressure pulsation transducer will get rid of restrict of reactor shut-down condition, and meet the needs of design. It could offer experience and reference for similar transducers' modification in civil nuclear plants.
