Methodology to Estimating Aquatic Dispersion of Effluents from Accidental and Routine Releases

Abstract

This paper presents a methodology to analysis of dispersion of radioactive materials in an aquatic environment, specifically for estuaries, based on the Regulatory Guide 1.113. The objective is to present an adaptation of methodology for computational user, that it is possible by means of the use of numerical approximations techniques. The methodology to be present consist in a numerical approximation of the Navier-Stokes Equation applied in a finite medium with known transport mechanisms, such as Coriolis Effect, floor drag, diffusion, salinity, temperature difference and adhesion per water molecule. The basis of methodology is substantiated in a transport diffusive-convection equation, which has similarity with the Partial Differential Burgues’ Equation for one dimension and with the Kardar-Parisi-Zhang Equation for multidimensional cases
