Abstract
METODO Y SISTEMA PARA CONTROLAR LA ESTABILIDAD DE UN REACTOR DE AGUA HIRVIENDO. SE UTILIZA UN ORDENADOR DIGITAL PARA CALCULAR DURANTE EL FUNCIONAMIENTO, A PARTIR DE VALORES DE ESTADO ESTABLE DISTRIBUIDOS DE POTENCIA, CIRCULACION, ENTALPIA Y PRESION SOLAMENTE, UN INDICE DE ESTABILIDAD PARA CONJUNTOS DE COMBUSTIBLES ELEGIDOS, TENIENDO EN CUENTA LA REALIMENTACION NUCLEAR ASI COMO LOS EFECTOS HIDRODINAMICOS DETALLADOS. ESTOS CALCULOS SE HACEN SOLO PARA CONJUNTOS DE COMBUSTIBLE ELEGIDOS POR SER MAS PROPENSOS A INESTABILIDAD DE NIVEL Y DISTRIBUCION AXIAL DE POTENCIA GENERADA. SI EL CONJUNTO MENOS ESTABLE ES INESTABLE SE RECALCULA ITERATIVAMENTE SU INDICE DE ESTABILIDAD UTILIZANDO CAMBIOS INCREMENTALES DE CIRCULACION O DE POSICION DE BARRAS DE CONTROL HASTA OBTENER UN ESTADO ESTABLE. EL AJUSTE ACUMULATIVO DE LA CIRCULACION O DE LA POSICION DE LAS BARRAS NECESARIO PARA LA ESTABILIDAD SE COMUNICA AL OPERARIO YPUEDE SER EFECTUADO MANUALMENTE O DE MANERA AUTOMATICA.
