Abstract
Dispositivo de media de la potencia local de un conjunto de elementos combustibles de un reactor nuclear, caracterizado porque incluye a) un cuerpo alargado, hecho de un material que es buen conductor del calor y de la electricidad, b) una serie de zonas configuradas como termómetro de rayos gamma, distribuidas axialmente a lo largo del citado cuerpo alargado conductor, donde cada zona configurada como termómetro de rayos gamma incluye un puente térmico y una fuente fría , así como un par de uniones, constitutivos de termopares dispuestos de manera que midan la diferencia de temperatura a través de un trayecto térmico que se extiende, sensiblemente según una sola dimensión, entre el citado puente térmico y la citada fuente fría, y porque la potencia creada por el conjunto de elementos combustibles en las proximidades de cada zona configurada como termómetro de rayos gamma, se deduce de las señales representativas de la citada diferencia de temperatura.
