Solución numérica de la reactividad en reactores nucleares

Abstract

La reactividad nuclear y la densidad de la población de neutrones son los parámetros más significativos al momento de cuantificar y describir físicamente el comportamiento de un reactor nuclear. Conocer el valor de la reactividad con suficiente precisión permite realizar el control y la operación segura de un reactor nuclear. Existen varios enfoques y métodos para calcular la reactividad reportados en la literatura. Sin embargo, en este artículo se propone usar la fórmula de Euler-Maclaurin para la solución numérica de la reactividad mediante la ecuación inversa de la cinética puntual que ha sido un modelo clave en el diseño de medidores de reactividad digital. Considerando la aproximación de una integral como una suma, en el desarrollo de la expansión de la integral continua en una versión discreta y tomando en cuenta únicamente los tres primeros números de Bernoulli y una aproximación que reduce las derivadas de mayor orden, es posible deducir un modelo que permite el cálculo de la reactividad nuclear en función de la densidad de la población de neutrones y de las constantes física en reactores térmicos que usan uranio como combustible nuclear.
