New NDT Documents in the Field of Nuclear Energy. Radiographic Inspection

A. V. Makarov

The article discusses some inconsistencies in the regulatory documentation for radiographic inspection in the field of atomic energy use. Attention is drawn to differences in permissible values of the heat-affected zone for fillet welds in two regulatory documents NP-105-18 and GOST R 05.05.07-2018, intended for nuclear energy. The pros and cons of selective inspection of joints along the length or quantity are discussed. Possible ways to correct the situation are proposed. It is noted that in GOST R 05.05.07-2018 the approach to calculating images on fittings and nozzles for the first time is explained in a similar way to the calculation when monitoring pipelines through one wall. This is a useful working tool for calculating the number of images, very popular in the practice of inspection.
