Embodiment Construction

[0042] The present invention proposes a method for determining the working path of radiation dose based on the nuclear island, such as figure 1 Shown. It includes the following steps. Step 1: Measure the radiation value of the nuclear island on site and generate a three-dimensional radiation dose zone map. The tool used to generate the three-dimensional map is Intergraph's SmartPlant 3D; Step 2: According to the three-dimensional radiation dose zone map, define the operator’s Multiple optional work routes to obtain multiple three-dimensional work paths for the operator; Step 3: Calculate the radiation dose value corresponding to each path according to the multiple three-dimensional work paths; Step 4: Manage files and steps according to the radiation dose of the operator 3 Obtain the radiation dose value corresponding to each path, and give the operator and the optimal work path arrangement for the operator. Three-dimensional radiation map generation

Abstract

The invention relates to a method and a system for determining a working path based on radiation dosage of a nuclear island, belonging to the field of nuclear radiation monitoring. The method comprises the following steps of: field measuring a radiation value of the nuclear island and generating a three-dimensional radiation dosage zoning picture; defining a plurality of selective working paths of workers according to the three-dimensional radiation dosage zoning picture to obtain a plurality of three-dimensional working paths of the workers; calculating radiation dosage values corresponding to the various paths according to the plurality of three-dimensional working paths; and giving an optimal working path of the workers according to a worker radiation dosage management file and the radiation dosage values corresponding to the various paths obtained in the step 3. According to the method and the system disclosed by the invention, workers and paths can be determined rapidly and effectively so that the workers are protected safely; and the method has the advantages of high efficiency and direct viewing.

Description

Technical field [0001] The invention belongs to the field of nuclear radiation monitoring, and in particular relates to a method and system for three-dimensional display of radiation zones based on a three-dimensional nuclear island layout model, and radiation dose designation for travel routes. Background technique [0002] A nuclear island is a collective term for the nuclear reactor and various systems related to the reactor in the reactor building of a nuclear power plant. It is a work area that may have radiation effects. For the personal safety of the staff, employees who enter the nuclear island operations usually need to carry radiation dose monitoring equipment with them to record the radiation dose received by the individual, and then send the current measurement results back to the "monitoring and dose management system" after the operation. This method is an afterthought, it lacks the planning of the detection area path and the safety analysis of the personnel dose, t...
