PURPOSE: To properly judge the degree of the effectiveness of hammering of a tube by particles projected to the inner face of the steam generator tube by providing a piezoelectric sensor arranged in contact with the wall of an outer housing near the end section of the outer housing kept in contact with the tube plate. CONSTITUTION: A moving unit 10 is inserted into a tube 3, a particle jet in gas is moved in a flexible tube 11 at a very high speed, and hammering is applied for compression toward the wall of the tube 3 in the radial direction by a contour portion, i.e., a tulip-like head 13a. The moving unit 10 lowers the inside of the outer housing 5 of a hammering tool to the original position at the end of this work. When the head 13a reaches the height of a piezoelectric sensor 20, the particles colliding with the inner wall of the outer housing 5 generate ultrasonic waves, and the ultrasonic waves are detected by the piezoelectric sensor 20 and converted into electrical signals. The electrical signals are measured by a voltmeter as a voltage measured value, and the degree of the effectiveness of particle hammering is judged.
