Abstract
In this contribution we discuss analytical modelling of radioactive substance
dispersion that results from either controlled or accidental release by nuclear power
plants. Our model is based on the three-dimensional advection–diffusion equation
with mean wind velocity field from observation. All meteorological parameters
are determined using the meso-scale Weather Research and Forecasting (WRF)
platform. The obtained solution permits us to simulate radioactive substances
dispersion in a turbulent regime in the environment around a power plant, which
is of interest for nuclear reactor accident scenarios and their related emergency
actions.We discuss the closed form method for solving the equation which is then
applied to radioactive substance dispersion. Finally, the results of the model are
presented.
Keywords: advection–diffusion equation, pollutant dispersion, analytical solution,
integral transform.
1 Introduction
While the renaissance of nuclear power was motivated by the increasing energy
demand and the related climate problem, the recent history of nuclear power,
more specifically two disastrous accidents, have forced focus on nuclear safety.
Although, experience gathered along nuclear reactor developments has sharpened
the rules and regulations that lead to the commissioning of latest generation
Keywords
