中文摘要：

针对火电厂安全评价工作的现状，基于网络技术开发了在线安全评价信息系统。该系统采用3层浏览器／服务器体系架构和动态服务器页面技术，弥补了当前火电厂安全评价手工作业的不足，使得火电厂安全性评价更加科学化、定量化。系统具有界面友好，简单实用，数据安全和可靠性高等特点，可以有效减轻安评人员的工作负担，提高工作效率，缩短安全评价周期。

英文摘要：

According to present situation of power plant security assessment by handwork or personal computer, a security assessment management information system （SAMIS） is developed based on intranet network technology. In SAMIS the 3-layer browser/server （B/S） architecture and active server page （ASP） technology are adopted to remedy the defects of present power plant security assessment by handwork, thus it makes power plant security assessment more scienfized and quantitized. The SAMIS possesses such advantages as friendly interface, simple and practicable, high reliability and data security, so it can effectively lighten workload of professional, improve working efficiency and shorten the period of security assessment.
