Abstract

Las unidades de varilla de control (10) incluyen sistemas totalmente digitales de monitoreo, alimentación y control (100) para operar las unidades; cada sistema de control (100) incluye distintos canales controlados por microprocesador (120, 130) que monitorean y manejan de forma independiente la información de posición de la unidad de varilla de control informada desde múltiples sensores de posición (18a, 18b) por unidad; los sistemas de control (100) funcionan como sistemas de control e información de varillas con hardware de nivel superior interconectado con operadores de plantas nucleares y otros sistemas de plantas; el hardware de nivel superior puede recibir instrucciones del operador e informar la posición de la varilla de control, así como informar errores detectados utilizando datos redundantes de los sensores múltiples (18a, 18b); los datos de posición recibidos de cada unidad se multiplexan a través de canales redundantes plurales (120, 130) para permitir la verificación del sistema utilizando datos de posición independientes, así como la operación del sistema en caso de que falle un solo canal o detector; las unidades de varilla de control (10) son capaces de posicionar y detectar la posición de los elementos de control en incrementos finos, como incrementos de 3 milímetros, con sensores de posición plurales (18a, 18b) que informan digitalmente el estado y la posición de la unidad.
