Abstract

The invention provides a 3dsMax-based nuclear facility model radiation field dosage simulation method. The method comprises the following steps of: constructing a model by 3dsMax software according to determined nuclear facility parameters, and storing a file in a 3DS format; importing a 3DS nuclear facility model file and obtaining model parameters; decomposing the 3dsMax nuclear facility model into voxels by using an octree method; writing determined voxel parameters and material information into an input card; importing the input card into a point nuclear integration program; calculating an accumulation factor; calculating a mean free path, in a radiation field, of a gamma ray; establishing a flux rate-dosage rate conversion factor, quality decay factors of chemical elements and materials and a single-layer accumulation factor database by utilizing an SQLite database engine; carrying out combined operation on a box by using a Boolean connective operator, and constructing a complicated radiation field geometric structure; and calculating a three-dimensional radiation field dosage by using a point nuclear integration method. The method provided by the invention is capable of realizing radiation field dosage calculation of complicated 3dsMax nuclear facility models with sizes, materials and energy parameters.

Description

technical field [0001] The invention relates to a nuclear decommissioning simulation method, in particular to a method for simulating the radiation field dose of a nuclear facility by using 3dsMax. 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 calculation results, it is necessary to perform radiation calculations on complex models. [0003] At present, t...
