Abstract

Dispositivo de protección térmica de una estructura de reactor nuclear refrigerado por un metal líquido, incluyendo dicha estructura una pared que delimita, con una borde libre que forma un umbral de vertedero, un espacio que se extiende verticalmente y recorrido según el sentido ascendente por un caudal derivado de metal líquido detraído a partir de un volumen principal de este metal líquido, en el cual se sumerge la parte inferior de dicha pared, caracterizado porque dicha virola llevo en su superficie opuesta a dicho espacio, una guarnición de elementos calorífugos, de tal manera que la lámina de vertido que circula hacia la parte inferior, aguas abajo de dicho umbral de vertedero, atraviesa dicha guarnición antes de ser restituida a dicho volumen principal de metal líquido.
