Abstract

REACTOR NUCLEAR DE AGUA LIGERA A PRESION Y CON VARIACION DEL ESPECTRO DE ENERGIA.COMPRENDE UN TABIQUE MACIZO (18) DE UN MATERIAL QUE REFLEJA LOS NEUTRONES DE ALTA ENERGIA EN LA PERIFERIA DEL NUCLEO (7) DEL REACTOR, DOS CAPAS (19 Y 20) DE MATERIAL QUE ABSORBE LOS NEUTRONES DE BAJA ENERGIA, Y QUE CONTIENE MATERIAL FERTIL, DISPUESTAS UNA EN LA PARTE INFERIOR Y LA OTRA EN LA PARTE SUPERIOR DEL NUCLEO (7), Y UN CONJUNTO DE BARRAS (27) DE VARIACION DEL ESPECTRO DE ENERGIA DE LOS NEUTRONES. LAS BARRAS (27) ESTAN ASOCIADAS A MECANISMOS QUE PERMITEN, YA INSERTARLAS COMPLETAMENTE EN EL NUCLEO (7), YA EXTRAERLAS COMPLETAMENTE. ESTAS BARRAS (27) SON DE UN MATERIAL QUE ABSORBE LOS NEUTRONES DE BAJA ENERGIA, Y QUE PERMITE UN DESPLAZAMIENTO DEL ESPECTRO DE LOS NEUTRONES HACIA LAS ALTAS ENERGIAS.
