摘　　要：阳江核电厂采用改进型压水堆CPR1000堆型,为确保安全壳截锥体超大环形预应力混凝土浇筑质量,经一系列配比试验和现场模拟试验研究,4号机组成功应用了自密实混凝土施工技术,并取得良好效果。作为核电行业同类结构应用自密实混凝土的首例,阳江核电4号机组安全壳截锥体自密实混凝土施工方法可为相关工程提供借鉴。Upgraded pressurized water reactor of CPR1000 was adopted in Yangjiang Nuclear Power Plant （NPP）. Based on a series of mixing tests and site mockup test studies, self-compacting concrete （ SCC ） technique was successfully applied to containment truncated cone of No.4 unit for the first time in NPP building industry, which could provide references for relevant projects with similar prestressed concrete structures.
