Abstract
Application of optimal complex of nondestructive testing (NDT) methods
can contribute significantly to the extension of life expectation, reliability and,
finally, safety, especially for very complex systems like nuclear power plants,
ground rocket complexes, etc.
The NPP is a complex system and its safety is related to the safety of each of
the system elements. Safety of power supply systems occupies one of the most
important roles in the NPP safety, because cables are potential source of fire.
This article deals with the task of complex optimization of NDT methods and contains
the idea to detect the set of possible and dangerous defects for NPP power system
cables taking into account the criteria of defect detection and efficiency level.
The application of multilevel one-criterion task of discrete programming is presented
and discussed. Efficiency of complex application of NDT methods depends on scheme
of testing organization, planning, data acquisition and processing and personnel
qualification.
Keywords: NDT methods; discrete optimization model; safety; power systems; cables
