2017年8月31日,由中核集团自主设计的华龙一号首堆示范工程——福清核电5号机组首台主泵泵壳在中国一重集团大连基地顺利通过验收完成交付。这标志着我国核电装备国产化设计、制造能力实现了新的跨越,设计、制造水平实现了新的提高。主泵是核电厂的心脏,而泵壳是主泵的关键设备之一。华龙一号的安全性和寿命对主泵泵壳设计、制造提出了更高要求。此次通过验收完成交付的首台华龙一号主泵泵壳是中核集团与中国一重、哈电集 On August 31, 2017, the first Hualong-1 head-stack demonstration project independently designed by CNNC, the first main pump casing of Fuqing NPP Unit 5, was successfully passed the inspection at China Yizhong Group Dalian Base and delivered. This marks a new leap forward in the localization design and manufacturing capability of nuclear power equipment in our country, and has achieved new improvements in the level of design and manufacture. The main pump is the heart of a nuclear power plant, and the pump housing is one of the key equipment for the main pump. Hualong on the 1st of the safety and life of the main pump casing design, manufacturing put forward higher requirements. The first Hualong-1 main pump casing that passed the acceptance inspection was delivered by China Nuclear Group and China First Heavy Industries
