Abstract

UN HAZ DE COMBUSTIBLE DE UN REACTOR NUCLEAR, EN EL QUE UNA PLURALIDAD DE BARRAS DE COMBUSTIBLE Y AL MENOS UNA BARRA DE AGUA SE EXTIENDEN ENTRE UNA PLACA SUPERIOR DE ANCLAJE Y UNA PLACA INFERIOR DE ANCLAJE, INCLUYE ADAPTADORES EXTREMOS SUPERIORES ASEGURADOS A UN PAR DE BARRAS DE AGUA Y QUE POSEEN PORCIONES DE MUESCA DEFINIDAS POR ASIENTOS SUPERIOR E INFERIOR. UN MECANISMO DE ENGANCHE PARA ASEGURAR EL PAR DE BARRAS DE AGUA A LA PLACA SUPERIOR DE ANCLAJE INCLUYE UNA BARRA DE ENGANCHE MONTADA SOBRE LA SUPERFICIE SUPERIOR DE LA PLACA SUPERIOR DE ANCLAJE Y QUE GIRA ENTRANDO Y SALIENDO DE LAS PORCIONES DE MUESCA DE LOS ADAPTADORES EXTREMOS CUANDO ESTOS SE EXTIENDEN POR ENCIMA DE LA SUPERFICIE SUPERIOR DE LA PLACA, TRAS LA INSTALACION DE LA PLACA SUPERIOR DE ANCLAJE SOBRE LA ESTRUCTURA DEL HAZ DE COMBUSTIBLE. SE HA DOTADO DE UN PERNO DE INMOVILIZACION QUE EVITA QUE LA BARRA DE ENGANCHE SE SEPARE ACCIDENTALMENTE.
