摘　　要：经过堆型论证、试验堆建设、商用堆攻关、系列堆型开发等四个阶段的发展,低温供热堆技术的固有安全性和技术成熟性已得到充分验证。作为清华大学核能与新能源技术研究院(简称“清华大学核研院”)最新开发的小型模块化压水堆,NHR200-Ⅱ保持了低温堆系列堆型的技术特点,采用一体化布置、全功率自然循环、自稳压方案,设有中间隔离回路和非能动安全系统,可实际消除大规模放射性释放、技术上无需采取场外应急措施,系统简化、运行操作简单,能够满足居民供暖、工业蒸汽、海水淡化、热电联供等多种需求。随着节能减排、空气污染治理等需求的逐步增强,NHR200-Ⅱ有望成为我国北方地区率先部署实施的供热堆型。Through reactor type arguments,test reactor construction,commercial reactor research,reactor series development,the inherent safety and maturation of low temperature nuclear heating reactor technology have been approved.As the latest small modular PWR type developed by the Institute of Nuclear and New Energy Technology(INET)of Tsinghua University,NHR200-Ⅱmaintains all the technological advantages,including integrated arrangement,full-power natural circulation,self-pressurization,intermediate loop isolation and passive safety.As the large-scale radioactivity release is essentially eliminated,the off-site emergency measures are technically unnecessary.Because of the high simplification of auxiliary systems,the operation of NHR200-Ⅱis quite simplified.NHR200-Ⅱcan satisfy various market requirements,such as district heating,industry steam supplying,seawater desalination and cogeneration.With the increasing needs of greenhouse gas emission reduction and air pollution control,NHR200-Ⅱis hoped to be the first deployed nuclear heating reactor in northern China.
