The use of the built digital twin for the assessment and prediction of radiation exposure to humans in the area of the PDEC location

The results of the use of the built digital twin for the assessment and prediction of radiation exposure to humans in the area of the Pilot Demonstrative Energy Complex (PDEC) location are presented. Information on radioactive releases from the BREST-OD-300 reactor during the reactor normal operation was collected, the impact of releases from developed different types of emergency scenarios was estimated as well. Based on these data, the radiation doses to the humans exposed to releases from the normally operated reactor were measured. The doses from designed and beyond-designed accidents were calculated. Based on the prognostic estimates obtained with the use of initial information, vector maps of the digital twin were created to assess and predict the radiation impact on humans in the area of the PDEC location. The results obtained can be used for the assessment of compliance with radiological safety, as well as to optimize radiation control programs for the PDEC.
