Abstract

BARRA DE CONTROL PARA REACTOR NUCLEAR. CONSISTE EN UNA SECCION ABSORBENTE (12) SOPORTADA POR UNA BARRA VERTICAL DE ACOPLAMIENTO (11). LA SECCION ABSORBENTE CONSTA DE CUATRO CHAPAS ABSORBENTES ALARGADAS (13-16) DOTADAS DE MUESCAS (17) Y PIEZAS DE CONEXION (27) EN EL CENTRO DE LA BARRA DE CONTROL Y QUE TIENEN UNA PLURALIDAD DE CANALES PERFORADOS (18). LOS SUPERIORES SE RELLENAN DE BARRAS DE HAFNIO, MIENTRAS QUE LOS QUE ESTAN SITUADOS POR DEBAJO SE LLENAN DE CARBURO DE BORO EN POLVO (20), SALVO LA PARTE MAS PERIFERICA (21) QUE SE RELLENA IGUALMENTE DE HAFNIO. PARA GUIAR LA BARRA DE CONTROL ENTRE LAS CAJAS DE COMBUSTIBLE DEL REACTOR, LLEVA UNOS SOPORTES DE GUIA (24) DE INCONEL Y TIENE TAMBIEN UN ASIDERO (25) PARA MANEJO DE LA BARRA CUANDO SE INSTALA Y SUSTITUYE.
