Abstract

EN UN ELEMENTO COMBUSTIBLE SE HAN INSERTADO Y/O ATORNILLADO LOS EXTREMOS FINALES (121) DE LAS BARRAS COMBUSTIBLES, TUBOS GUIA, TUBOS DE REFRIGERANTE, ETC. EN UNA PLACA BASE (1), Y SE HAN ASEGURADO CON UN BULON (124) PARA EVITAR QUE SE LEVANTEN. EN BARRAS COMBUSTIBLES, ESPECIALMENTE EN BARRAS COMBUSTIBLES QUE NO SE EXTIENDEN A LO LARGO DE TODA UNA BARRA NORMAL, SE HA ATORNILLADO EL BULON A LAS PIEZAS DE UNION DE TAL MODO QUE, RESULTA UN CIERRE DE BAYONETA DESMONTABLE. EN TUBOS DE REFRIGERANTE DE REACTORES DE AGUA EN EBULLICION, SE HA PREVISTO ESPECIALMENTE UNA UNION ATORNILLADA, LA CUAL ESTA ASEGURADA FIJAMENTE MEDIANTE UN BULON CONTRA LA TORSION.
