The Reliability Optimization Allocation Method of Control Rod Drive Mechanism Based on GO Method

Abstract

In order to improve the reliability of The Control Rod Drive Mechanism (CRDM), a reliability trade-off method was proposed, which aims at the total cost-reliability. Firstly, the Goal-Oriented (GO) model of the CRDM was established. Then, the total cost-reliability composed of Research and Development (R&D) production cost and operation and maintenance cost was used as the objective function of the model. Finally, based on GO methodology and Genetic Algorithm (GA), the reliability trade-off optimization allocation results of the CRDM were obtained, which proves the feasibility of the proposed method.
