The results of 3D modeling of personnel’s working conditions in radiation hazardous conditions of the "Ukryttya" object performed with the HVRC VRdose Planner software. Dose loads were assessed for personnel during the dismantling of the metal frame on the roof of the "Ukryttya" object. The obtained modeling data showed good convergence with the data that was obtained during the development of a working design for the dismantling of this construction. These simulations are very well correlated to the results of the safety analysis report. For operations with similar radiation conditions, radiation levels are also the same. However, the HVRC VRdose Planner software allows for more accurate modelling of radiation doses in space, and for this reason, for certain operations, exposure levels are 20 – 30 % higher than the design levels. This is explained by more precise estimates of radiation conditions compared to calculations performed by conservative methods. With a more detailed understanding of the radiation situation at the work site, it is possible to increase the level of personnel protection and reduce the time spent in high radiation fields. The values of radiation doses, which are calculated not by the conservative, but by the actual method, may be used for further activity on the "Ukryttya" object.
