Abstract

Piscina de combustible nuclear consumido. La presente invención se refiere a una piscina de combustible nuclear consumido (12) que tiene un volumen de agua en el cual pueden sumergirse conjuntos de combustible nuclear consumido (14), que incluye un sensor del nivel de agua (16), que comprende: una pluralidad de termopares calentados (34) respectivamente colocados a diferentes alturas dentro de la piscina (12), teniendo cada termopar calentado una primera salida eléctrica representativa de la temperatura a la altura de colocación correspondiente; un calentador (54, 56, 58) para calentar los termopares calentados (34); medios (18, 20) para transmitir las primeras salidas eléctricas a una posición remota blindada para su monitorización; y un comparador (22, 24, 26, 28, 30, 32) para comparar las salidas eléctricas de termopares adyacentes.
