Abstract

Un reactor nuclear de neutrones rápidos contiene un núcleo de reactor nuclear que tiene una serie de ubicaciones de dispositivo. Algunas ubicaciones de dispositivo en el núcleo de reactor nuclear contienen dispositivos de montaje de combustible nuclear fisionable y fértil. Una o más de otras ubicaciones de dispositivo en el núcleo de reactor nuclear contienen los dispositivos de aumento de reactividad Doppler que amplifican la negatividad del coeficiente de reactividad Doppler dentro del núcleo de reactor nuclear. En algunas implementaciones, un dispositivo de aumento de reactividad Doppler también puede reducir el coeficiente de temperatura del fluido refrigerante dentro del núcleo de reactor nuclear. En consecuencia, el dispositivo de aumento de reactividad Doppler contribuye a un núcleo de reactor nuclear más estable.
