Hydropneumatic accumulator

Description

The invention proposes a hydropneumatic accumulator with bladder. It may be used on a nuclear reactor to inject borated water in the primary circuit in case of accident. The invention proposes a hydropneumatic accumulator in which the risks of explosion, especially by diesel effect, are suppressed or at least considerably reduced. This result is obtained by the presence on the accumulator transfer tube of diffusers realized in a material compatible with the material of the bladder and provided with holes having an important section

Abstract (French)

La presente invention a pour objet un accumulateur hydropneumatique a vessie. Il peut etre utilise sur un reacteur nucleaire pour injecter de l'eau boree dans le circuit primaire en cas d'accident. L'invention propose un accumulateur hydropneumatique dans lequel les risques d'explosion, notamment par effet diesel, sont supprimes ou au moins considerablement reduits. Ce resultat est obtenu par la presence, sur le tube de transfert de l'accumulateur, de diffuseurs realises en un materiau compatible avec celui de la vessie et comportant des orifices ayant une section de passage importante
