Main Parameters Influencing the Level of Labile Contamination and the Removal Factor
Autor: Pierrick Agullo, Alban Gossard, Gilles Ranchoux, Emmanuel Porcheron, Fabrice Petitot
Publikováno v: Journal of Nuclear Engineering and Radiation Science. 9
Several nuclear facilities are currently being decommissioned in France, on CEA and EDF sites. The decommissioning process as a whole, with cutting operations and nuclear waste management presents workers with significant risks of exposure. The aim o

Flash-Boiling Characterization During Ingress of Coolant Event for Dust Issue in ITER
Autor: Benjamin Blaisot, Emmanuel Porcheron, Olivier Praud, Véronique Roig
Publikováno v: Journal of Nuclear Engineering and Radiation Science. 8
Dust resuspension inside the vacuum vessel (VV) is one of the safety issues of the fusion reactor ITER. Plasma interaction with the plasma facing components (PFC) leads to their erosion, generating dust. One of the accident scenarios leading to dust
