Abstract

LA PLACA DE FILTRACION (10) DISPUESTA EN LA PARTE INFERIOR DEL ENSAMBLAJE COMBUSTIBLE, QUE PROPORCIONA LA RETENCION DE LAS PARTICULAS CONTENIDAS EN EL FLUIDO DE REFRIGERACION DEL REACTOR, CONSTA AL MENOS DE UNA ZONA ACTIVA PERFORADA CON ORIFICIOS (12) DE TAMAÑO DETERMINADO EN FUNCION DEL TAMAÑO DE LAS PARTICULAS A RETENER. LAS ZONAS ACTIVAS DE LA PLACA DE FILTRACION QUEDAN FRENTE A UN ORIFICIO DE CONDUCCION DE AGUA A TRAVES DE LA PLACA INFERIOR DEL NUCLEO DEL REACTOR CUANDO EL ENSAMBLAJE ESTA EN SERVICIO. LAS ABERTURAS DE CONDUCCION DEL AGUA DE LA PLACA DE FILTRACION (10) PUEDEN ESTAR CONSTITUIDAS POR CORTES DE FORMA CUADRADA, TRIANGULAR O POR UNAS PARTES EMBUTIDAS DE LA PLACA E INCLUSO ESTAR DELIMITADAS POR UNAS LAMINAS PARALELAS QUE CONSTITUYEN UNA REJILLA.
