Abstract

UN SISTEMA DE PROTECCION PARA UNA INSTALACION DE ENERGIA NUCLEAR, CERRANDO EL REACTOR EN RESPUESTA A LA DETECCION DE UNA CANTIDAD DE FLUJO NEGATIVA DETERMINANTE DE UNA VARILLA DESPRENDIBLE, PARA PROTECCION DEL DISPOSITIVO DE DESCONEXION SI LA CANTIDAD DE FLUJO NEGATIVA ESPECIFICADA ES PRECEDIDA EN UN INTERVALO DE TIEMPO POR UNA CANTIDAD DE FLUJO POSITIVA DETERMINANTE DE UN RECHAZO DE UNA RED DE CARGA CUANDO EL MODERADOR DEL COEFICIENTE DE TEMPERATURA ES ALTAMENTE NEGATIVO.
