摘要: 为了满足华龙一号(HPR1000)事故条件下的应急响应,需要开发一套应急工况评价系统,用于基于征兆的堆芯损伤评价和释放源项估算。本文给出了华龙一号应急工况评价系统(ECAS-HPR1000)的总体设计,包括软件框架、评价模块、平台和接口开发等,该系统采用跨平台的JAVA语言开发,以MySQL数据库作为数据存储,支持Windows 和Linux操作系统。该系统包括五个子系统,分别是基础数据采集和管理子系统、堆芯损伤评价子系统、释放源项计算子系统、评价结果展示子系统和用户权限管理子系统。该系统可以基于实时工况数据,评价堆芯损伤状态和程度,并计算出堆芯释放到一回路、安全壳和环境的放射性核素的量,并考虑了华龙一号双层安全壳对计算结果的影响。

Abstract: For meeting with the requirements of preparedness and response in case of a nuclear emergency of HPR1000,a system used to assess the core damage status and to estimate the source term released to the environment must be developed.The development of Emergency Condition Assessment System for HPR1000 (ECAS-HPR1000) was introduced,including its software framework,assessment modules,platform and data interfaces,etc.The system adopts the JAVA language as the platform,and open source MySQL as the data management system,supporting Windows and Linux OS.There are five subsystems,including 1) basic data acquisition subsystem,real-time acquiring the reactor operation parameters from Distributed Control System (DCS),2) core damage assessment subsystem,which used to assess the core damage status and degree,3) source term estimation subsystem,calculating the amount of radioactive material released from the core into the primary coolant system,containment and environment,4) assessment results display subsystem,5) user authorization management subsystem.

Key words: core damage assessment, source term estimate, nuclear emergency
