Mcu-PD Code Calculation of Personnel Irradiation Dose in an Accident with Coolant Leakage in Serviced Enclosures in NPP with VVER-1000

Calculations of the personnel irradiation dose rate were performed to assess the radiation consequences of the rupturing of a tube in the sampling line in a complex preparing samples for automated chemical monitoring of the primary loop of NPP with VVER-1000. The calculations were performed by the Monte Carlo method using the MCU-PD high-precision code based on data on the activity of fission products in the primary coolant using ICRP-developed anthropomorphic voxel-phantoms of a standard person.
