大亚湾核电站反应堆保护系统T1试验台的研制与应用

The Development and Application for Protection System T1 Tester in Daya Bay Nuclear Power Station

保护系统是核电站最重要的安全系统之一。为了保证系统的可用性,根据核安全法规的要求,必须对系统的功能进行定期试验以便及时发现系统内部潜在的故障。大亚湾核电站的试验台由于老化,可靠性降低,影响了核电站的安全。遵循相关设计标准,充分考虑现场实际使用需求、技术可靠性等因素,研制了新型的试验台。大亚湾核电站一年多的现场运行表明,新研制的试验台完全达到了预定的设计要求。

Protection system is one of the most important systems in nuclear power station. According to the requirement of nuclear regulation, and in order to ensure the system availability, periodic test must be done to test system function to find potential fault. The reliability of tester in Daya Bay nuclear power station decreased because of aging, which affects nuclear safety. A new tester was developed by considering the related design standards, requirement from site operation and technique reliability. The more than one year operation in Daya Bay nuclear power station demonstrated that this new tester meets the expected requirement.
