Abstract

UN REACTOR NUCLEAR QUE ES ACCIONADO DURANTE LOS CAMBIOS DE CARGA CON UNOS CAMBIOS MINIMOS DE LA CONCENTRACION DE BORO A BASE DE MANTENER BARRAS GRISES TOTALMENTE INTRODUCIDAS EN EL NUCLEO DURANTE UNA OPERACION EN ESTADO ESTACIONARIO Y DE AJUSTAR EL DESPLAZAMIENTO AXIAL EN REPUESTA A LOS CAMBIOS DE POTENCIA. CUANDO SE ESPERA QUE SE PRODUZCA UNA REDUCCION DE LA DEMANDA DE POTENCIA, EL DESPLAZAMIENTO AXIAL DE LA DISTRIBUCION DE POTENCIA AXIAL EN EL NUCLEO DEL REACTOR SE AJUSTA HACIA ABAJO EN UN -10% APROXIMADAMENTE, A BASE DE INSERTAR UNA SERIE POTENTE DE BARRAS DE CONTROL DE DESPLAZAMIENTO AXIAL EN LA PARTE SUPERIOR DEL NUCLEO Y DE RETIRAR POCO A POCO LAS BARRAS GRISES. LA REACTIVIDAD DEL NUCLEO SE AJUSTA PREFERENTEMENTE INICIALMENTE UTILIZANDO UNA SERIE DE BARRAS GRISES CON UN VALOR PARECIDO AL DE LAS BARRAS GRISES QUE SE MANTIENEN TOTALMENTE INTRODUCIDAS EN EL NUCLEO Y SOLO CUANDO SEA NECESARIO UN CONTROL ADICIONAL DE LA REACTIVIDAD SE UTILIZAN BARRAS DE CONTROL NEGRAS CONVENCIONALES. LAS BARRAS GRISES QUE NORMALMENTE SE MANTIENEN TOTALMENTE INSERTADAS EN EL NUCLEO, SE PUEDEN UTILIZAR TAMBIEN PARA CONTROLAR LA REACTIVIDAD Y PROPORCIONAR UNA REACTIVIDAD MAYOR PARA UNA VUELTA A LA POTENCIA PLENA. PREFERENTEMENTE, HAY UNA SUPERPOSICION CERO ENTRE LAS BARRAS GRISES, DE MODO QUE UNA SERIE SE ENCUENTRA TOTALMENTE INSERTADA EN EL NUCLEO ANTES DE QUE SE INSERTE LA OTRA SERIE PARA REDUCIR LA REACTIVIDAD.
