The method of ultrasonic nondestructive testing (USNDT) of the temperature fields and thermal tensions in the bodies of nuclear reactors of indicated type in unstationary thermal conditions has been grounded on the obtained results. The expedience of subsequent industrial introduction of proposed method is shown . Product Description popup.authors popup.nrat_date 2020-04-02 Close
