Modification of the Monte Carlo method for calculation of the influence of unknown placement of solid radioactive waste on the uncertainty of dose fields at different overall container dimensions

An approach to estimating the uncertainty of initial data in calculations by the Monte Carlo method is considered. The relative geometrical position of parts of the analyzed system is assumed to be unknown. The influence of different approximations in the description of the geometrical shape of syst...

Summary:An approach to estimating the uncertainty of initial data in calculations by the Monte Carlo method is considered. The relative geometrical position of parts of the analyzed system is assumed to be unknown. The influence of different approximations in the description of the geometrical shape of system objects is studied. The effect of unknown location and approximate shape description of solid radioactive waste in the container on the magnitude of dose fields is considered for photon transport problems.
