Gamma spectroscopy in water cooled reactors

Creators

Description

Gamma spectroscopy analysis of spent fuels in power reactors; study of two typical cases: determination of the power distribution by the mean of the activity of a low periodic element (Lanthanum 140) and determination of the burnup absolute rate by examining the ratio of Cesium 134 and Cesium 137 activities. Measures were realized on fuel solutions and on fuel assemblies. Development of a power distribution map of the assemblies and comparison with the results of a three dimensional calculation of core evolution

Abstract (French)

Analyse par spectrometie gamma du combustible irradie dans les reacteurs de puissance; etude de deux cas caracteristiques: determinations de la repartition de la puissance a l'aide de l'activite d'un corps a periode courte (le lanthane 140) et determination du taux de combustion absolu grace au rapport des activites du Cesium 134 et du Cesium 137. Les mesures ont ete effectuees sur des solutions et sur des assemblages. Etablissement d'une carte de distribution de puissance dans les assemblages et comparaison avec les resultats d'un calcul d'evolution du coeur a trois dimensions
