Abstract

CONEXION DE BARRA DE AGUA EN UN HAZ DE COMBUSTIBLE PARA REACTORES NUCLEARES. EN UN CONJUNTO DE HACES DE COMBUSTIBLE (B) PARA UN REACTOR NUCLEAR, EN DONDE UNA PLURALIDAD DE BARRAS DE COMBUSTIBLE (R) Y, AL MENOS, UNA BARRA DE AGUA (W), SE EXTIENDEN ENTRE UNA PLACA SUPERIOR DE ANCLAJE Y UNA PLACA INFERIOR DE ANCLAJE. UNA MEJORA INCLUYE LA UTILIZACION DE UNA CONEXION FIJA ENTRE LA BARRA DE AGUA (W) Y LA PLACA INFERIOR DE ANCLAJE (L) QUE FIJA INCLUYE UN TAPON INFERIOR ROSCADO DE FONDO DE LA BARRA DE AGUA Y UN ORIFICIO ROSCADO SITUADO EN LA PLACA INFERIOR DE ANCLAJE ADAPTADO PARA RECIBIR EL TAPON INFERIOR ROSCADO DE FONDO (50) QUE ESTA CONFORMADO CON UNA RANURA DIAMETRAL (54) Y EL REFUERZO (56) ESTA CONFORMADO CON UN PAR DE RANURAS (60, 62), DE MANERA QUE ESTAN ALINEADOS CUANDO EL TAPON INFERIOR ROSCADO DE FONDO (50) ESTA ROSCADO DENTRO DEL REFUERZO (56); Y UNA LLAVE (64) PARA FIJAR LA BARRA DE AGUA, EVITANDO SU MOVIMIENTO ROTACIONAL.
