Abstract
EL ARMAZON NUCLEAR SUPERIOR E INFERIOR (3,4) EN ESTRUCTURAS NUCLEARES GENERICAS (3,4) PORTA UNA SERIE DE CLAVIJAS CENTRADAS (10), QUE SE ELEVAN CON SUS EXTREMOS LIBRES HACIA LAS ESCOTADURAS DE UNA PIEZA EXTREMA DEL ELEMENTO COMBUSTIBLE. ESPECIALMENTE, LAS TUERCAS DE SUJECCION DE LOS PASADORES, SITUADAS EN EL ARMAZON NUCLEAR SUPERIOR, RESULTAN DE DIFICIL ACCESO CUANDO SE QUIERE CAMBIARLAS. HAY QUE PROCURAR, POR TANTO, QUE HAYA INSTALACIONES NUCLEARES, QUE NO POSEAN UNA SUJECCION DE SEGURIDAD POR MEDIO DE TUERCAS EN LAS ESPIGAS CENTRALES. PARA ELLO SE PROPONE QUE HAYA UNA ESPIGA CENTRAL (10) CON UNA PERFORACION CENTRAL CONTINUA (22). LA PERFORACION CENTRAL, EN SU EXTREMO ADOSADO AL ELEMENTO COMBUSTIBLE, ESTA CONFIGURADA COMO PERFORACION GRADUAL (23) DE RECORRIDO CONICO. LA PERFORACION GRADUAL TIENE UN TAPON RELATIVO A LA ESPIGA CENTRAL, QUE SE PUEDE AJUSTAR EN DIRECCION AXIAL. CUYA SUPERFICIE LATERAL ESTA CONFIGURADA EN LA MISMA DIRECCION E IDENTICO GRADIENTE DE LA MISMA FORMA CUNEIFORME QUELA PERFORACION CENTRAL. LA ESPIGA CENTRAL IMPLANTA CON LA PERFORACION (18) UN ENLACE DE AJUSTE SIN HOLGURA. A LA ALTURA DE LA PERFORACION GRADUAL, LA SUPERFICIE LATERAL DE LA ESPIGA CENTRAL ESTA DOTADA CON UNA MUESCA QUE, TRAS EL MOVIMIENTO RELATIVO DEL TAPON, ESTABLECE UN ENLACE, CON FORMA DE CIERRE, CON LA PARED DE LA PERFORACION (18).
