Problems solved by technology

[0004] 1. Due to the lack of effective path planning, it is difficult to ensure the lowest possible exposure dose level and the shortest stay time during the process of stepping out, which increases the risk of personnel exposure dose
[0005] 2. Relying solely on the actual experience of the staff to carry out path checkpoints, lack of effective maintenance path optimization means

Abstract

The invention discloses a maintenance path planning method and device for a nuclear power station. The method comprises the following steps: according to the radiation zoning and the distribution of the radiation hot spots in the nuclear power station, the three-dimensional digital nuclear power station is made into a navigation grid needed for path searching; according to the preset heuristic search algorithm, the appropriate maintenance path is selected in the navigation grid, so that the radiation dose to the maintenance personnel passing through the maintenance path is the lowest. The radiation data information is introduced into the three-dimensional scene of the nuclear power station and the maintenance exposure dose level is taken as the evaluation criterion of route search, a heuristic search method is used to search the path automatically in the three-dimensional scene of nuclear power plant, the maintenance personnel can effectively approach the maintenance target area underthe condition that the radiation dose level of the maintenance personnel is kept at a reasonable and low level, and the maintenance path plan efficiency is greatly improved, so that the maintenance work of the nuclear power plant can be carried out quickly and reliably.

Description

technical field [0001] The invention relates to the technical field of route planning, in particular to a method and device for planning a maintenance route of a nuclear power plant. Background technique [0002] At present, before the maintenance of nuclear power plants starts, radiation protection personnel must measure the radiation level of the work area in advance. Only within the allowable radiation dose range, maintenance personnel can enter the work area for on-site environmental investigation. At present, the on-site inspection of nuclear power maintenance can only rely on the actual experience of the maintenance personnel, and the distribution characteristics of the radiation dose field cannot be analyzed in advance, and the radiation dose during the operation cannot be pre-evaluated, so that the maintenance path cannot be effectively planned in advance. Ensure that exposure doses are kept as low as possible. [0003] Therefore, the existing selection of maintenan...
