Russia invents a new method for nondestructive testing of nuclear reactors

The new non-destructive testing (NDT) method for quality assurance of nuclear reactors invented by the Moscow State Nuclear Research University (MEPhI) has made it possible to discover potential weaknesses in reactor structures. With this new technology, it is possible for people to get information about them when cracks begin to form and other weaknesses in the materials used in the reactor. This method can identify fatigue cracks in the reactor steel material and predict where cracks will appear.

At present, there are four kinds of commonly used nondestructive testing equipments, including Portable Digital Radiography Systems, Ultrasonic flaw detection equipment, Magnetic detection equipment and liquid penetrant detection equipment. The emergence of new technologies will break the current pattern.
