This consensus standard 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.
