摘要
"华龙一号"示范工程是我国自主研发的三代核电机型,其控制系统采用全数字化仪控系统和先进控制室设计(简称DCS系统设计)。"华龙一号"首堆DCS系统设计符合国内以及国际上最新的法规、导则和标准的要求,吸收了国内多个数字化核电厂的建设和运行经验,并充分借鉴国际先进核电厂DCS系统设计理念。与二代加核电厂相比,"华龙一号"首堆工程DCS系统设计充分吸收了福岛核电厂事故后一系列的技术改进,提高了自动化控制水平,满足事故后30 min不干预的设计原则;提高了仪控设备的鉴定水平,满足0.3g地面最大加速度的抗震要求;提高了对设计扩展工况(包括严重事故工况)的防御能力,在发生严重事故且全厂断电工况下,仍能在72 h内为核电厂的严重事故缓解提供必要的监控手段。
The HPR1000 demonstration project of is a third generation nuclear power plant which is designed and developed by China independently. The fully digital technology based on the distributed control system and advanced main control room is employed in the I＆C system （known as the DCS design） to implement the con trol and monitoring function. In this project, the design of I＆C system complies with the latest national nuclear safety codes, standards and criteria, refers to related international codes and standards, absorbs the construc tion and operational experience of most domestic power plants, and takes advantages of advanced DCS design of international power plants. The DCS design for the HPR1000 demonstration project implements a series of tech nical improvements based on the Fukushima accident. The automatic control level has been improved so that the plant can be operated automatically for 30 min without intervention during the accident. The qualification for the I＆C system and components has been largely improved, such as the seismic qualification can meet the 0.3g maximum ground acceleration. The I＆C system defense capabilities for the design extension conditions （included severe accident） have been improved, and it can still provide necessary operational and monitoring means for 72 h during the severe accident condition when occurring the station blackout.
