摘要：和睦系统（FirmSys）是一套成熟可靠的核电站安全级数字化仪控平台，已成功应用于多个百万千瓦级核电机组的保护系统。为满足各类型核电机组的改造需求，FirmSys平台越来越多地应用到小型核电项目中。按照法规和标准要求，需对安全级保护系统进行定期试验。定期试验方案设计是数字保护系统的关键设计技术之一。本文以某试验堆为例，基于FirmSys平台进行小型核电保护系统的定期试验设计，提出了一套完整的定期试验解决方案，简化了定期试验操作流程，优化了定期试验步骤。可为同类型的小型核电保护系统的定期试验方案设计提供思路与参考。

Abstract:FirmSys is mature and reliable digital nuclear safetyinst rument and control system platform, which has been applied tothe protection system of many million kilowatts nuclear power plant.In order to meet the needs of renovation and reformation project ofnuclear power plant, FirmSys is increasingly applied to small reactor protection system. According to the require ment of related standards and regulations, the reactor protection system should be periodically tested. The periodic test design is one of the key design technologiesfor digital protection systems. Taking a research reactor as an examplea complete set of periodic test solutions are presented in this paper，which simplifies the operation program of the periodic test scheme and optimizes the procedure of the periodic test. It can provide ideas andreferences for the design of periodic test scheme of the same type of small nuclear power protection system.

Key words: Periodic test scheme; FirmSys; Research reactor; Protectionsystem
