In order to obtain the optimal pipeline support and hanger layout plan during design of radioactive waste treatment system, a pipeline support and hanger layout optimization method was proposed, and the corresponding pipeline parameterized finite element model was established, with the pipeline stress as the optimization target and the relevant standards as constraints conditions, a combined algorithm of global scanning and zero-order optimization was used to determine the optimal position of the support and hanger to complete result accounting. An example was used to introduce the method flow and a comprehensive orthogonal test method was used, and the correct calculation of the built pipeline finite element model was verified with the help of CAESAR II software. The method in this paper avoids a lot of manual trial calculation in the pipeline layout process, greatly improves the design efficiency, and can obtain the maximum stress margin, and the safety performance of radioactive waste treatment system is improved.
