A new method for controlling the damageability of a material used in the equipment of nuclear power plants and the hard-and software for its realization

摘要

Scientific, methodological, and technical aspects of the problem of control over the state of a material used in vital heavy-duty elements of the equipment of nuclear power plants in the stage of dispersed damage accumulation are considered. An interpretation of the function of damageability that allows its hardware determination on the basis of a complex of spectral-acoustic measurements is proposed. A spectral-acoustic system intended for controlling the damageability of a material is described. The results of its application to the estimation of the damage accumulated in specimens made of steel 12Cr18Ni9Ti are presented for the case of low-cycle loading.
