EG G Rocky Flats TRAC 1991 Winter Validation Study

Technical Report ·
OSTI ID:5966339
The TRAC code consists of a computerized Gaussian puff model configured as an emergency response predictive technique that will employ regional topographic data, political and demographic data bases along with site specific emission source characteristics and meteorological data. The system developed around the TRAC code is intended to meet emergency response, emergency planning, risk assessment and regulatory compliance needs. The code provides on site and off site predictive information which can be used to diagnose and respond to nuclear and other hazard situations associated with the Rocky Flats Plant operation. The TRAC code has been developed by the Emergency Assessment Section of EG G Rocky Flats. This experimental plan describes one step in the evaluation and verification of the code. In total, the code is to be evaluated and verified by a multi-step program which because of its extent and complex nature is being carried out over a period exceeding five years in duration. The code will be evaluated and verified through employment of numerous field experimental data sets which are generated during a wide range of meteorological dispersion conditions. An initial experimental data set was generated for use in verification of the code during the summer of 1987 and late special site specific trajectory data were generated during an ongoing yearlong plume trajectory study that was initiated in 1990. The set of experiments which is described by this plan (called the Winter Validation Study, or WVS) will be used for further validation. It will span a representative portion of winter conditions during 1991 and will encompass several atmospheric dispersion experiments, all involving very detailed documentation of concurrent regional atmospheric transport, diffusion and meteorological conditions. 3 figs., 2 tabs.
