Recommendations for Portable Supplemental Meteorological Instrumentation for Incident Response

摘要

The document is intended to provide the Nuclear Regulatory Commission with specifications for a Supplemental Meteorological System (SMS) to aid in the response to an incident at nuclear power plant sites. At the time of an incident, there is an immediate operational need to define evacuation areas and to evaluate the consequences of radioactive releases to the atmosphere. Releases can be at any elevation, and knowledge of the upper level winds must be obtained to determine correct trajectory patterns. Sites are situated in nonuniform terrain; therefore, trajectory determination requires knowledge of winds at several points. A measure of stability is required to forecast the degree of horizontal and vertical spreading of effluents.
