Abstract EN
The capabilities of the SCALE6.1/MAVRIC hybrid shielding methodology (CADIS and FW-CADIS) were demonstrated when applied to a realistic deep penetration Monte Carlo (MC) shielding problem of a full-scale PWR containment model.
Automatic preparation of variance reduction (VR) parameters is based on deterministic transport theory (SN method) providing the space-energy importance function.
The aim of this paper was to determine the neutron-gamma dose rate distributions over large portions of PWR containment with uniformly small MC uncertainties.
The sources of ionizing radiation included fission neutrons and photons from the reactor and photons from the activated primary coolant.
We investigated benefits and differences of FW-CADIS over CADIS methodology for the objective of the uniform MC particle density in the desired tally regions.
Memory intense deterministic module was used with broad group library “v7_27n19g” opposed to the fine group library “v7_200n47g” used for final MC simulation.
Compared with CADIS and with the analog MC, FW-CADIS drastically improved MC dose rate distributions.
Modern shielding problems with large spatial domains require not only extensive computational resources but also understanding of the underlying physics and numerical interdependence between SN-MC modules.
The results of the dose rates throughout the containment are presented and discussed for different volumetric adjoint sources.
