Analysis of fission products emission of a leaking fuel pin. Thermal cycling effect
Creators
Description
Experimental study of fission products release mechanism of a fuel pin with a previous leak in the primary coolant circuit of a PWR. The zircaloy 4 cladding, containing uranium dioxide, has a leak 0.3-0.5 mm in diameter near the plug and is irradiated in a pressurized water loop (at 130 bars) in a temperature range 300-3300C. Fission products analysis is performed by gamma spectrometry. Rare gases and iodines production and composition are studied versus the linear power between 200 and 500 W/cm and the thermal cycling

Les travaux experimentaux presentes sont relatifs a l'etude des mecanismes d'emission des produits de fission par un crayon presentant un defaut initial d'etancheite dans le circuit primaire d'un reacteur PWR. La gaine en zircaloy 4 contenant les pastilles de dioxyde d'uranium presente un defaut d'etancheite de 0,3 a 0,5 mm de diametre pres du bouchon. Les irradiations ont ete conduites dans une boucle a eau pressurisee a 130 bars a une temperature de 300 a 3300C. L'analyse des produits de fission est effectuee par spectrometrie gamma. On determine l'evolution des gaz rares et des iodes en fonction de la puissance lineaire entre 200 et 500 W/cm et des cyclages thermiquesFiles
