In recent years, a large amount of work has been carried out on the unloading and testing of witness samples from operating units of the Ukrainian NPP (including the reconstruction program). By this time, Ukraine has already produced enough experimental data of impact test specimens for further systematization and analysis. The issue of temperature dependence of scattering is poorly understood in our country, which adds additional uncertainty to the rationale for NPP safe operation. Matlab has developed code that performs calculations and systematization of the experimental data of the sample witnesses in the form of a table. Product Description popup.authors Holiak Mykola H.
