Abstract

EL INVENTO CONSTA DE UN SUB-MONTAJE DE TOBERA SUPERIOR (12) PARA UN MONTAJE DE COMBUSTIBLE NUCLEAR, QUE INCLUYE UNA PLACA INFERIOR O ADAPTADORA (26), UNA PLACA DE SUJECION O SUPERIOR (30) Y MUELLES DE SUJECION (60) DISPUESTOS ENTRE LA PLACA SUPERIOR Y LA PLACA ADAPTADORA PARA TRASMITIR A ESTA ULTIMA, FUERZAS DE SUJECION APLICADAS A LA PLACA SUPERIOR. LA PLACA SUPERIOR (30) ES PARTE DE UN ESTRUCTURA SUPERIOR (24) QUE INCLUYE UN CIERRE EN LA PARED LATERAL (32), INTEGRAMENTE CONECTADO CON EL BORDE PERIFERICO EXTERIOR DE LA PLACA SUPERIOR (30) Y DEPENDIENDO DE EL (30A). LA PLACA ADAPTADORA (26) ESTA DISPUESTA DENTRO DEL CIERRE DE LA PARED LATERAL PERMITIENDO UN MOVIMIENTO RELATIVO ENTRE ESTA Y LA ESTRUCTURA SUPERIOR (24). ESTA DISPOSICION PERMITE QUE LA PLACA ADAPTADORA (30) SE MONTE EN UN NIVEL MAS ALTO EN LOS MANGUITOS DE LA GUIA DE CONTROL DE BARRA (16) PERMITIENDO UN MAYOR CRECIMIENTO DE COMBUSTIBLE EN LAS BARRAS Y AUN DEJA ESPACIO SUFICIENTE ENTRE LAS PLACAS SUPERIOR Y ADAPTADORA PARA MANEJAR EL EQUIPO QUE SE HA DE AJUSTAR.
