WWER-1000堆型安全壳通风放射性监测

Containment ventilation radioactivity monitoring of WWER-1000 reactors

介绍了田湾核电站WWER-1000堆型安全壳通风系统放射性监测的通道设置及相应的功能。通过蒸汽发生器间循环冷却系统监测通道1KLA20CR002报警的实例,表明WWER-1000堆型安全壳通风系统放射性监测具有及时警报、准确定位报警区域、方便确认报警的真实性、便于维护监测通道的特点。

This article introduces the setting and function of containment ventilation system radioactivity monitoring channels of WWER-1000 reactors in TNPS. And it focuses on analyzing the warning of 1KLA20CR002 monitoring channel of steam generator recirculation cooling system, which proved that the containment ventilation radioactivity monitoring of WWER-1000 reactors have the characters of warning on time, locating the warning areas accurately, easily affirming the trueness of warning and maintaining the monitoring channels convenientty.
