Abstract

Procedimiento de control de los efectos de reactividad debidos a las variaciones de potencia en los reactores nucleares de agua a presión que utilizan el desplazamiento, en conjuntos combustibles, de racimos móviles de material absorbente, así como el boro soluble, para la corrección de los efectos a largo plazo de reactividad, caracterizado por el hecho de que: se desplazan en función de la potencia solicitada a la turbina únicamente, grupos compuestos de racimos de material absorbente, en que uno, por lo menos, tiene una anti-reactividad inferior a 700 pcm, para hacer variar la potencia del reactor, se desplaza simultáneamente un grupo, denominado grupo R, compuesto de racimos muy absorbentes, en función de la diferencia que existe, en cada instante, entre la temperatura media del núcleo del reactor y una temperatura de referencia, función del nivel de potencia solicitada, pudiéndose desplazar este grupo entre bornes de regulación definidos por el modo de funcionamiento del reactor y el estado de evolución del núcleo de este reactor, finalmente, porque se hace variar la concentración en boro soluble del fluido primario del reactor, con objeto de mantener el grupo R en su gama, en el curso de la corrección de los efectos a largo plazo de reactividad
