Development of ultrasonic imaging technique used in sodium-cooled fast reactor is very important for improving the safety of the reactor. Therefore, many countries carried out study on under-sodium ultrasonic imaging technique. Based on the application of ultrasonic imaging technique to demonstrate the sodium-cooled fast reactor, and the introduction and study on the experimental data of sodium loop testing platform, this paper describes and analyzes the key factor of R＆D progress abroad in this regard, and propose the feasibility of using ultrasonic imaging system technique in sodium-cooled fast reactor and some problems need to be solved.
