Non-hurtful inspection of neutron radiation generated embrittlement of reactor pressure container steel is an intensely important task in nuclear manufacturing. The aim of the present study search out suggest and to test experimentally a novel drawing method, named magnetic adjusting testing (MAT). The influence of neutron irradiation depravity on reactor pressure bowl steel was investigated. Large blocks were irradiated by neutrons at a depressed irradiation hotness. Samples were measured by MAT method before and subsequently the neutron irradiation. It was proved that the modification of the recorded drawing parameters on account of the neutron irradiation was well perceptible by this non-destructive method. It was likewise shown that the influence of neutron improvement could be detected accompanying a reasonable signal-to-clamor ratio even through the cladding. In two together cases (on the cladded side and from the bottom base material) a good, nearly linear equating was found between drawing parameters and crazily determined ductile to tense transition hotness. It was also demonstrated, by what method the base material and the cladding itself maybe inspected separately from each one by this non-destructive drawing measurements. It was raise that with the proper choice of the magnetizing yoke measure, these two different fabrics could be measured alone of each other. Our results can help for the future efficient application of magnetic forms in the regular check of nuclear power plants.
