Abstract

Appareil pour réduire le niveau de puissance d'un réacteur nucléaire en cas de défaillance de la circulation du réfrigérant primaire. Il comporte un absorbeur 30 de neutrons et un élément 34 s'allongeant sous l'effet de la chaleur et sensible à la température du réfrigérant primaire. Lorsque cette température augmente, l'allongement de l'élément 34 provoque un déplacement de l'absorbeur de neutrons vers l'intérieur du coeur du réacteur, afin de diminuer la puissance produite par ce dernier. Domaine d'application : réacteurs nucléaires, surrégénérateurs, etc.
