摘要：
Qualitative and quantitative analyses on the VERDON-1 sample made it possible to obtain valuable information on fission product behaviour in the fuel during the test. A promising methodology based on the quantitative results of post-test characterisations has been implemented to assess the release fraction of non gamma-emitter fission products. The order of magnitude of the estimated release fractions for each fission product was consistent with their class of volatility. (C) 2017 Elsevier B.V. All rights reserved.
