摘　　要：作为先进压水堆核电站关键技术研究项目之—,参照西屋电气公司和法马通公司的相关技术,研制了线功率密度保护的物理模型。通过限制线功率密度,可以限制燃料芯块的温度。在保证安全运行的基础上,能更准确地描述堆芯的运行状况,提供更大的灵活性。本文叙述了线功率密度保护的基本原理和物理模型。As one of the term for the research on the key technology studied in advanced PWR nuclear power plant, a theoretic model of linear power protection is developed, based on the relevant technologies from Westinghouse Electric Corporation and FRAMATOME. The temperature of fuel pellets can be limited by linear power density restriction. The operation status of reactor core can be described accurately and larger dexterity is obtained. This report presents its basic principles and physics model.
