Method for locating failed fuel elements in a nuclear reactor

Creators

Description

Process for locating failed fuel elements in a nuclear reactor, particularly in the case of a fast reactor. The characteristic of this process is that the age of the defective fuel element is measured by determining the ratio between two fission substances constituted by two stable gaseous isotopes having available gas formation kinetics differing according to the specific burnup, for example the stable isotopes of xenon

Abstract (French)

Procede de localisation de ruptures de gaine dans un reacteur nucleaire, ce procede s'appliquant plus specialement a un reacteur a neutrons rapides, caracterise en ce que l'on effectue la mesure de l'age de l'element combustible defectueux en determinant le rapport entre deux produits de fission constitues par deux isotopes gazeux stables ayant des cinetiques de formation de gaz disponible differentes en fonction du taux de combustion, par exemple les isotopes stables du xenon
