Modelos de crecimiento de burbujas en residuos radiactivos

Abstract

Se propone un modelo para el crecimiento de burbujas de helio en material nuclear que reproduce el comportamiento cualitativo observado experimentalmente para la distribución de tamaños de burbujas. El modelo tiene estructura de sistema infinito de ecuaciones diferenciales acopladas con una restricción no local y una fuente no acotada. Se sugiere una reformulación mediante transformadas de Laplace que reduce el sistema a una ecuación integrodiferencial para la densidad de monómenos y expresa las demás densidades como convoluciones de la densidad de monómeros con núcleos aproximables por gaussianas. Esta reformulación permite establecer resultados de existencia global y obtener información sobre propiedades cualitativas, así como sobre el impacto de distintos parámetros en la evolución de la población de burbujas, fundamentales para controlar su dinámica.
