FIELD: nuclear engineering.
SUBSTANCE: invention relates to the field of radiation monitoring and ensuring the radiation safety of nuclear facilities and can be used to detect the area of radionuclide leakage and assess its magnitude during the operation of light-water nuclear reactors. The method for determining the area of leakage of radioactive nitrogen in the steam generators of nuclear reactors of the KLT-40 type additionally contains stages at which the presence of radionuclide in the steam is determined by the measured value of the ionizing radiation dose rate and the vapor density at the steam outlet point to the turbine using the given dimensional coefficient characterizing the content of radioactive nitrogen in the mass unit of steam at the steam outlet point to the turbine during its passage through the steampipe.
EFFECT: providing the possibility of detecting the area of leakage of radioactive nitrogen in the steam generators of KLT-40 type nuclear reactors.
