Abstract

Abstract: In order to ensure that the temperature of the main feed water and the main steam pipe is at the design value, there is a thick insulation layer outside the main pipe line. According to the requirements of the specification, after a certain period of time, the insulation layer here needs to be replaced. However, due to the relatively high dose of radioactivity here, maintenance personnel are subject to a certain dose of radiation. We use 3D ergonomics simulation method to establish a 3D model of the scene here, simulate the correct disassembly and installation process of the operator, make the maintenance personnel familiar with the environment and operation process, reduce errors, shorten the operation time, and finally shorten the inspection cycle. This achieves increased safety and reduced overhaul time at low cost.
