Abstract
Perfeccionamientos introducidos en reactores nucleares con refrigeración por agua; con recipiente a presión que tiene una entrada así como una salida para el líquido de refrigeración; con un núcleo reactor dispuesto en el referido recipiente y por el cual pasa el líquido refrigerante en sentido ascendente, con un conjunto de sujeción para el núcleo reactor, con el fin de compensar las fuerzas de elevación de éste núcleo reactor debido a la caída de presión en el flujo del líquido refrigerante a través del núcleo reactor; caracterizados porque dentro del referido recipiente está dispuesta una pared transversal de estancamiento, por encima de la cual una primera cámara de combustión es sometida a una presión que es esencialmente igual a la presión de entrada del líquido refrigerante existiendo dentro de una segunda cámara de combustión, dispuesta por debajo de la mencionada pared y por encima del referido núcleo reactor, una presión que es esencialmente igual a la presión de salida del líquido refrigerante; y que la mencionada pared transversal de estancamiento tiene unos dispositivos verticales de guía para unos pistones desplazables de forma relativa cuyas caras superiores son expuestas a la presión existente en la mencionada primera cámara de combustión, mientras que la cara inferior de los mismos está expuesta a la presión existente en la referida segunda cámara de combustión, estando el mencionado pistón acoplado con el referido núcleo reactor, con el fin de servir como dispositivo de sujeción para éste último.
