DEVELOPMENT OF A REAL TIME LONG RANGE RADIOACTIVE PLUME TRANSPORT SIMULATION MODEL

THE FEASIBILITY OF DEVELOPMENT OF A NEW LONG RANGE RADIOACTIVE PLUME TRANSPORT CODE IS PROPOSED. NEW APPROACHES TO ESTIMATE THE RADIOACTIVE DECAY, WET AND DRY DEPOSITION, PARTICULATE COAGULATION, AND ATMOSPHERIC PARAMETERS WILL BE EXPLORED AND A SIMPLE, IDEALIZED EVALUATION OF THESE ALGORITHMS WILL BE MADE IN PHASE I OF THE PROPOSED EFFORT. BASED ON THESE STUDIES A) AN APPROPRIATE NEAR SOURCE RISE AND DISPERSION MODEL, B) AN APPROPRIATE OPERATIONAL HEMISPHERIC SCALE MODEL AND C) A WET AND DRY WIND DEPOSITION MODEL FOR RADIOACTIVE PARTICLES AND GASES WILL BE IDENTIFIED FOR INCORPORATION IN AN AIRSHED MODEL TO BE CARRIED OUT IN PHASE II.
