Virtual simulation system for nuclear safety emergency

Abstract

The invention relates to the technical field of nuclear power plant three-dimensional simulation, and discloses a nuclear safety emergency virtual simulation system which comprises a three-dimensional virtual static scene, and a nuclear power plant geometric model, a pipeline fluid model, a radiation dose display model and a virtual roaming user model are arranged in the virtual static scene. The radiation dose display model comprises a profile dose calculation module and a maintenance dose evaluation module, and the profile dose calculation module is used for performing dose rate calculation on the sectioned pipeline fluid model; the maintenance dose evaluation module is used for calculating the dose value of the virtual roaming user model in the process of simulating the maintenance displacement in the three-dimensional virtual static scene; the system estimates the injury degree of the maintenance personnel under the actual condition, so that the injury degree of the maintenance personnel under the actual condition is estimated, an area with high radiation intensity is avoided, a path where a small dose of radiation is accumulated in the decommissioning process is selected, the injury of the maintenance personnel is reduced, and the safety of the personnel is ensured.

Description

technical field [0001] The invention relates to the technical field of three-dimensional simulation of nuclear power plants, in particular to a virtual simulation system for nuclear safety emergency. Background technique [0002] Due to the imperceptibility of nuclear radiation dose, with the help of multi-perception, immersion, interaction and conception of virtual reality technology, the complex and dangerous nuclear power plant environment can be simulated, which is helpful for employees in the process of nuclear power plant inspection and maintenance. In the design of radiation protection, the existing research is relatively simple in the form of virtual reality, only simulating the nuclear power environment, assisting personnel to understand the structure and scale of the entire nuclear power plant, and has not solved how to reduce the number of actual workers based on the virtual simulation system. The nuclear radiation dose received during maintenance in the nuclear p...
