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。Abstract: 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．
