Abstract

Perfeccionamiento en los aparatos para la comprobación in situ de la integridad de tubos en los generadores de vapor, que contienen enfriador procedente de un rector nuclear, caracterizados porque el aparato comprende en combinación; un detector que produce un efecto eléctrico que corresponde a cambios en la integridad del tubo, un cable conectado a dicho detector y a un grupo de accionamiento situado alejado del generador de vapor para arrastrar dicho detector a través del tubo, un conducto atravesando por dicho cable entre dicho grupo de accionamiento y dicho tubo y teniendo un extremo abierto junto a la boca de dicho tubo y medios que producen una circulación de medio secante a través de dicho conducto que se descarga a través de dicho extremo abierto a fin de eliminar de esta manera el enfriador que se adhiere a la superficie de dicho cable mientras se arrastra dicho detector a través de dicho tubo.
