| Abstract | The detect corrosion cracks at an early stage of formation and determination of their causes is important. For example, PWR-1000 corrosion cracking occurs in the welding unit coolant reservoir to the body of the steam generator (welded joint zone № 111). It is known to cause cracking of the deposits are iron and copper compounds in the form of sludge that accumulates with time in the pockets welding assembly. Objectives: The theoretical aspects of the method of scanning contact potentiometry underlying functional electrophysical diagnostics are discussed, and a summary of the mathematical model to build the profile of the surface diagnosed is given. Using portable electrophysical complex functional diagnostics will allow us to carry out non-destructive testing on the process equipment of nuclear power plants. A software package included in the settlement and software module that provides processing of incoming information creates the database and make the necessary calculations, contains test and diagnostic programs, as well as visualization of the results. |
| Keywords | electrophysical diagnostics and non-destructive testing, scanning the contact potentiometry, a mathematical model for the construction of the surface profile according to the electric potential difference function, NPP. |
