Abstract

Abstract:

Background: The driving force and resistance in nitrate natural circulation loop(NNCL) are almost in the same magnitude. The system performance of NNCL can be influenced by lots of parameters, such as environment, material, structural and operation condition, thus selection of key parameters affecting NNCL is very important. Purpose:The aim is toidentify the key parameters affecting NNCL reliability. Methods: The analytic hierarchy process(AHP) is an effective method to analyze the importance of each parameter to the NNCL reliability using experts' judgment to structure judgment matrix and calculate the parameters' weight. In this paper, an AHP model and judgment matrix is established for the 40 parameters. Results: 12key parameters are selected including physical parameters, structural parameters and operating parameters. Conclusion: The results show that the most important parameters affecting NNCL reliability are air temperature, heating power and air flow rate in the NNCL operational phase.
