ANS 3.11-2015（R2020）规定了在商业核电站、美国能源部/国家核安全局核设施以及其他国家或国际核设施收集、组装、处理、存储和传播气象信息的标准。虽然充分讨论了成熟的监测和分析方法，但本次修订提供了更新系统（包括硬件和软件）的信息，以及跟上科学发展的更现代的方法。通过实施本标准收集、处理、存储和传播的气象数据用于支持核设施的整个生命周期（即选址、建造、运行和退役）。气象数据被用于与确定环境影响相关的大量应用中，以便在常规发布和设计中进行后果评估- 基础事故评估，支持应急准备和响应计划，以及其他重要应用，例如评估超出设计基础的事件。气象数据的使用也可以在各种类型的环境、净化和退役、空气质量、风荷载和工程研究中发挥重要作用。气象数据的其他用途包括评估环境修复活动、工业卫生、建筑和废物管理。关键词:环境、核安全、选址

ANS 3.11-2015 (R2020) provides criteria for gathering, assembling, processing, storing, and disseminating meteorological information at commercial nuclear electric generating stations, U.S. Department of Energy / National Nuclear Security Administration nuclear facilities, and other national or international nuclear facilities. While well-established monitoring and analysis methods are adequately addressed, this revision provides information on newer systems, both hardware and software, and more modern methods to keep up with the state of the science.Meteorological data collected, processed, stored, and disseminated through implementation of this standard are utilized to support the full life cycle (i.e., siting, construction, operation, and decommissioning) of nuclear facilities. The meteorological data are employed in a large number of applications associated with determining environmental impacts, enabling consequence assessments in routine release and design-basis accident evaluations, supporting emergency preparedness and response programs, and other important applications, such as evaluating beyond design-basis events.The use of meteorological data can also play an important role in various types of environmental, decontamination and decommissioning, air quality, wind loading, and engineering studies. Other uses of meteorological data include assessments of environmental remediation activities, industrial hygiene, construction, and waste management.Keywords:environmental, nuclear safety, siting
