Abstract

METODO PARA INSTALAR Y RETIRAR UNA BARRA DE VENENO COMBUSTIBLE EN REACTORES NUCLEARES. EL NUCLEO DE UN REACTOR DE POTENCIA, DEL TIPO DE AGUA BAJO PRESION, ESTA CONSTITUIDO POR GRUPOS DE CONJUNTOS DE COMBUSTIBLE DISPUESTOS EN UNA CONFIGURACION CILINDRICA, ESTANDO FORMADO CADA GRUPO POR UNAS DOSCIENTAS BARRAS DE COMBUSTIBLE, PARALELOS ENTRE SI, Y CON PASTILLAS DE DIOXIDO DE URANIO EN SU INTERIOR. EL PROCESO DE MANIPULACION DE LAS BARRAS, QUE VAN MONTADAS SOBRE UNAS ARAÑAS MECANICAS, SE COMPONE DE LAS SIGUIENTES OPERACIONES: 1) INTRODUCIR UNA ESPIGA, DISPUESTA SOBRE LA BARRA, EN EL INTERIOR DE UN AGUJERO DE LA ARAÑA, SIGUIENDO UNA DIRECCION AXIAL. 2) APLICAR UNA PRESION A LA ESPIGA SUFICIENTE PARA REBASAR LA FUERZA QUE LA SUJETA AL AGUJERO, Y 3) EXTRAER LA ESPIGA DEL AGUJERO.
