Conference Article: Out-of-pile helium loop for liftoff experiments
Blanchard, R.J.; Bros, A.; Gentil, J. (CEA Centre d'Etudes Nucleaires de Grenoble, 38 (France))Abstract
A helium loop has been developed to study the fission products re-entrainment. Its principal characteristics are described, as also the experimental method which has been used. The studies have shown that the principal parameter affecting the lift-off of fission products and dust particles is the shear ratio. A preliminary study has been started concerning the dust particles, particularly about their nature and their contribution to the fission products transportation.
