Abstract

INSTALACION TERMOMETRICA DE RAYOS GAMMA PARA REACTORES NUCLEARES. CARACTERIZADA PORQUE INCLUYE UN AGUJERO (22), PRACTICADO EN EL NUCLEO DEL REACTOR NUCLEAR, Y UN TERMOMETRO GAMMA (21), INTRODUCIDO EN EL Y CALENTADO POR LOS RAYOS GAMMA DEL NUCLEO. EL TERMOMETRO (21) Y EL AGUJERO (22) ESTAN CONECTADOS TERMICAMENTE CON EL FIN DE QUE LA TEMPERATURA MARCADA POR EL TERMOMETRO SEA REPRESENTATIVA DE LA DEL REACTOR. EL TERMOMETRO (21) SE COMPONE DE UNA GRAN MASA DE METAL (23) Y OTRAS MAS REDUCIDAS (24, 25), CON UNA VAINA (26) ESTAMPADA SOBRE LA MASA (23), DEJANDO LOS ESPACIOS VACIOS (27, 28) QUE AISLAN TERMICAMENTE LAS MASAS (24, 25) QUE SE CALIENTAN MAS QUE LA GRAN MASA (23). EL PUENTE TERMICO ESTA CONSTITUIDO POR UNOS ANILLOS (29) ALOJADOS EN UNAS RANURAS (31) Y UNOS MUELLES (30) QUE PERMITEN QUE SE ADAPTEN A LA CONFIGURACION Y DIAMETRO DEL AGUJERO (22). R
