Analysis of Candidate Core Materials in SCWR Based on Boiler Materials of SCU
-
摘要: 堆芯材料是超临界水冷却反应堆(SCWR)能否实现的重要制约因素之一,而与其工作环境最为相近的当属超临界火电站(SCU)锅炉用材。本文对比分析了SCWR堆芯材料与SCU锅炉用材的力学性能、使用温度、工作介质等要求,提出SCU锅炉用材T23、T91、T122、316、TP347H(FG)、Super304H可作为SCWR堆芯候选材料。Abstract: The core material of supercritical water cooled reactor（SCWR）is one of the sticking points for SCWR,while the operational conditions of supercritical unit（SCU）are greatly similar to SCWR.Me-chanical property,operating temperature and service environment for the materials of both the core of SCWR and the boiler of SCU were compared and discussed.Candidate materials of supercritical water cooled reactor were been put forward in this paper,such as T23,T91,T122,316,TP347H（FG）and Super304H.
