BN800:定位于闭式燃料循环的先进钠冷快堆核电站

BN800:The advance sodium cooled fast reator plant based on dose fuel sycle

作为实际上快堆技术最先进的国家之一,俄罗斯始终站在快堆技术发展的前沿。在成功运行了电功率为600 MW的BN600快堆核电站近30年,以及在其基础上改进并完成数次设计优化数十年后,终于决定建设别洛雅尔斯基核电站4号机组(BN800快堆电站)。BN800快堆核电站被认为是世界上正在付诸工程的最为先进的快堆核电机组。我国的快堆技术发展已有数十年,随着中国实验快堆即将投运,中国示范快堆电站已经提上议事日程。同时,以快堆为关键环节的闭式燃料循环发展战略已经引起了我国相关领域专家和决策层的关注。本文作者在其多年从事中俄快堆技术合作积累的经验基础上,参考俄罗斯发表的最新并且权威的关于BN800快堆核电站的文献,编译成综合性介绍文章,供我国从事核燃料循环战略研究、快堆技术发展研究等相关领域的领导和专家参考。

As one of the advanced countries with actually fastest reactor technology, Russia has always taken a leading role in the forefront of the development of fast reactor technology. After successful operation of BN600 fast reactor nuclear power station with a capacity of six hundred thousand kilowatts of electric power for nearly 30 years, and after a few decades of several design optimization improved and completed on its basis, it is finally decided to build Unit 4 of Beloyarsk nuclear power station （BN800 fast reactor power station）. The BN800 fast reactor nuclear power station is considered to be the project of the world＇s most advanced fast reactor nuclear power being put into implementation. The fast reactor technology in China has been developed for decades. With the Chinese pilot fast reactor to be put into operation soon, the Chinese model fast reactor power station has been put on the agenda. Meanwhile, the closed fuel cycle development strategy with fast reactor as key aspect has given rise to the concern of experts and decision-making level in relevant areas. Based on the experiences accumulated in many years in dealing the Sino-Russian cooperation in fast reactor technology, with reference to the latest Russian published and authoritative literatures regarding BN800 fast reactor nuclear power station, the author compiled this article into a comprehensive introduction for reference by leaders and experts dealing in the related fields of nuclear fuel cycle strategy and fast reactor technology development researches, etc.
