Abstract

The EPA-approved model CAP-88 PC is a commonly used radiological atmospheric dispersion model. This model is approved for use in the demonstration of compliance with atmospheric emission regulations for radionuclides. The model includes a large library of meteorological data for use across the United States. While these files cover a large spatial area, and are generally acceptable for regulatory use, it may also be desirable to use onsite meteorological data as an input to the CAP-88 PC model. Currently CAP-88 PC does not include this capability in an easy to implement manner. This paper describes a work-around process for preparing onsite data for use in CAP-88 PC and the conversion of the data into the proper format for use in CAP-88 PC. Note that the use of site-specific data may not be acceptable for regulatory use.
