Determination of atmospheric dispersion factors in emergency situations in Almirante Alvaro Alberto nuclear power plant - unit 1
Description
The necessity of Knowing the atmospheric dispersion factor, used to obtain the first estimation dose in the public case for accidents with releasing of radioactive material to atmosphere in Almirante Alvaro Alberto nuclear power plant - unit I, lead to the development of a fast and efficient method to determine the dilution factors, in a pre-determined distance from the source, to be used in the dose estimate. The ACID computer program for pocket calculation allow to obtain the meteorological information to evaluate the dose. In this work the mathemathical models used and the program developed are described. (Author)
Abstract (Portuguese)
A necessidade de se conhecer os fatores de dispersao atmosferica, usados para avaliacoes iniciais de dose no publico em caso de acidente com liberacao de material radioativo para atmosfera, na Central Nuclear Almirante Alvaro Alberto - Unidade I, implicou na obtencao de um metodo rapido e eficiente, que possibilitasse com um minimo de informacoes meteorologicas, determinar os fatores de diluicao, a uma distancia pre-estabelecida da fonte, a serem aplicados nas estimativas de dose. O programa ACID, elaborado pelo autor para uma calculadora de bolso programavel, permite que se obtenha rapidamente as informacoes meteorologicas para avaliacao de dose. Neste trabalho sao descritos os modelos de calculo utilizados e o programa ACID. (Autor)Files
