It is presented the review of published data about different dangerous damaging of critical equipment at a nuclear power unit during industrial operation, which indicate the urgency of the problem of evaluation of structural materials operability in elements of nuclear power plants equipment. Limited opportunities of experimental approaches are noted, and in connection with this circumstance, based on mathematical modelling evaluation for structural materials operability in elements of equipment of nuclear power plants is discussed. The general approach, in which evaluation for structural materials operability in elements of nuclear power plants equipment is reduced to a system of several related initial-boundary-value problems, is proposed. The correspondences rules between the mathematical objects and relationships of the proposed approach and the processes in equipment and structural materials of elements of nuclear power plants equipment are considered.
