Abstract

"MONTAGEM DE COMBUSTìVEL PARA UM REATOR NUCLEAR, E, BOCAL DE FUNDO DE FILTRO DE DETRITOS PARA A MESMA". Um bocal de fundo de filtro de detritos para uma montagem de combustível nuclear tendo uma saia de suporte e uma placa de topo. A placa de bocal de topo tem definidos por ela uma pluralidade de furos de fluxo. A cavidade axial por cada furo de fluxo é contornada como um venturi. Preferivelmente, o venturi é formado com a entrada chanfrada dupla.
