我国高温气冷堆发展战略研究

Development Strategy of High Temperature Gas Cooled Reactor in China

高温气冷堆和在此基础上发展起来的超高温气冷堆是第四代核能系统研发重点的6种堆型之一。本文介绍了高温气冷堆的特点,对高温气冷堆技术在国内外的最新研发进展进行了简要综述,对高温气冷堆的发展定位等问题进行了讨论。在此基础上对我国高温气冷堆发展路线进行了展望。我国高温气冷堆技术历经跟踪、跨越和自主创新,目前在商业规模模块式高温气冷堆核电站技术上处于世界领先地位。在此基础上,我国正在启动部署后续60万千瓦级模块式高温气冷堆核电机组的研发和配套关键技术的攻关工作,以进一步推动高温气冷堆技术的产业化,保持我国在该领域的国际领先优势。

High temperature gas cooled reactor(HTGR)together with its successor,the very high temperature reactor,is one of the six nuclear energy systems identified and selected by the Generation IV International Forum for further development.The paper briefly summarizes the technical characteristics of HTGR and reviews the recent research and development status of HTGR technology at home and abroad.It also discusses the strategic positioning of HTGR in China and looks ahead to the HTGR technology development road map in China.China has gone through the stages such as tracking,stepping over,and independent innovation in the past years,and now is in the front-runner status with respect to the commercial-level HTGR nuclear power plant.On this basis,China is working on the design of 600 MW pebble bed HTGR(HTR-PM600),so as to further promote industrialization of the HTGR technology and stay ahead in this field.
