摘　　要："华龙一号"是由中核集团和中广核集团共同开发,具有完整自主知识产权的百万千瓦级压水堆核电机组,"华龙一号"核岛厂房外部事件防护设计按照现行核安全法规要求进行了技术改进。在抗震设计方面,建立核岛厂房三维实体有限元模型,在提高抗震设计加速度水平下采用多组地基参数进行包络分析,提高了核岛厂房抗震设计的安全性和适用性;采用流固耦合动力非线性分析方法计算安全相关重要水池和水箱中水体在地震作用下的晃动效应。遵照新版HAF102的要求,将大型商用飞机撞击作为一种超设计基准外部事件进行评估。HPR1000 Units are developed by CNPE GNPE jointly.They are independent designs of 1000 MWe PWR nuclear power units.In the design of nuclear island buildings,technical improvements are involved according to up to date nuclear safety rules comparing to Generation 2 NPPs.In the aspect of seismic design,3D FE models are established,the input design basis earthquake acceleration level is increased,and muti-sets of foundation parameters are considered to enhance the safety and feasibility of the seismic design for NI buildings.Sloshing effects of liquids restored in safety related tanks are analyzed through use of nonlinear fluid-structure interaction FE analysis methods.Conforming to newly published HAF 102,large commercial aircraft crash are considered as an exceeding design basis event.Impact assessments are conducted for NI buildings.
