For the purpose of monitoring for compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT), the International Monitoring System (IMS) is being established that includes 40 sensor systems for atmospheric xenon radioactivity. Its purpose is to monitor the atmosphere for signatures that may indicate a nuclear explosion. Normal operational releases of radioxenon from nuclear facilities can regularly be observed by these very high-sensitive noble gas systems. Existing best estimates of releases for a generic year are unlikely to apply for any specific year at the level of individual facilities because their releases are highly variable and can change by several orders of magnitude from year to year. In this paper, best knowledge of the radioxenon emission inventory from nuclear power plants (NPPs) is collected for the calendar year 2014. The distribution function for each CTBT relevant radioxenon isotope is derived from all releases from NPPs as reported for 2014. The data of this paper can be used for developing and validating methods based on atmospheric transport modelling that are designed to enhance understanding of the impact of known sources on the IMS background observations.

2014 日历年全球核电厂放射性氙排放清单

为了监测《全面禁止核试验条约》（CTBT）的遵守情况，正在建立国际监测系统（IMS），其中包括 40 个大气氙放射性传感器系统。其目的是监测大气中可能指示核爆炸的特征。这些非常高灵敏度的惰性气体系统可以定期观察到核设施放射性氙的正常运行释放。现有对通用年份释放的最佳估计不太可能适用于单个设施层面的任何特定年份，因为它们的释放变化很大，并且每年都可能发生几个数量级的变化。在本文中，收集了 2014 日历年核电厂 (NPP) 放射性氙排放清单的最佳知识。
