3dsMax nuclear facility model radiation field dosage distribution simulation method

Abstract

The invention provides a 3dsMax nuclear facility model radiation field dosage distribution simulation method. The method comprises the steps that 1, 3dsMax software constructs a model according to determined nuclear facility parameters, and a file is saved as a 3DS format; 2, a 3DS nuclear facility model file is imported, and model parameters are obtained; 3, a bounding box and a tetrahedron are constructed; 4, determined voxel parameters and texture information are written as an input card; 5, a plane triangle is dispersed into pixels; 6, according to attribute values of voxels, entity voxels are constructed; 7, the determined voxel parameters and physical property information are written into the input card; 8, a point kernel integration method is used for calculating three-dimensional radiation field dosage distribution. Rapid assignment is directly performed on the facility size, texture and energy parameters inside the 3dsMax software; radiation field dosage distribution calculation of the complex nuclear facility model internally with a hole is achieved.

Description

technical field [0001] The invention relates to a nuclear decommissioning simulation method, in particular to a simulation method for the radiation field dose distribution of a 3dsMax nuclear facility model with a cavity inside. Background technique [0002] Maintenance and decommissioning of nuclear facilities is an important link in the life cycle of nuclear facilities. When formulating the maintenance or decommissioning strategy of nuclear facilities, it is necessary to optimize the maintenance and decommissioning scheme and the path of the staff during the decommissioning operation, so as to reduce the radiation damage to the staff, which requires an accurate understanding of the three-dimensional radiation dose distribution of nuclear facilities In this case, a radiation simulation is performed. In the radiation simulation process, in order to obtain accurate virtual radiation field dose distribution calculation results, it is necessary to perform radiation calculation...
