Nuclear Product Design Knowledge System Based on FMEA Method in New Product Development

Abstract

Nuclear power product manufactories are continually striving to reduce both the amount and the cost of product maintenance, whilst at the same time ensuring that the nuclear power product safety, reliability, and integrity are not compromised. The demand for high-quality and low-cost products with short development time, especially for complex nuclear power products, e.g., nuclear power reheat valve, has forced the product development team to focus on the various effective product development strategies. In this paper, authors explore the applicability of knowledge-based technologies to competitive new reheat valve product design and development. Based on the proposed approach and methodologies, a web-based and service-oriented system supporting new reheat valve product design has been developed, which can assist inexperienced users to perform failure modes and effects analysis (FMEA) analysis,and most important, to get knowledge stored in database for future quality and reliability improvement. The system will help to enhance new reheat valve product stability at the stage of product conceptual design. A framework of system based on FMEA approach for new reheat valve product design is proposed in this paper.
