Some CEA research activities in support of Fukushima Daiichi fuel debris retrieval

Christophe Journeau, Viviane Bouyer, Arthur Denoix, Andrea Bachrata et autres

Fuel debris retrieval is one of the important challenges in view of Fukushima Daiichi decommissioning. Indeed, hundreds of tons of fuel debris will have to be cut and collected in the 3 units that have been subject to core meltdown in March …

Incorporation of silver in borosilicate nuclear glass

Élise Régnier, Damien Perret, Charlène Vallat, Sylvain Mure et autres

This paper investigates the incorporation of silver into borosilicate nuclear glasses, focusing on the effects of glass composition and melting temperature. Results demonstrate that the iron-content and thermal history of the glass are two parameters that influence the oxidation state of silver …

Experiences from the cutting of metallic blocks from simulant Fukushima Daiichi fuel debris

Christophe Journeau, Diego Alonso Restrepo Molina, Emmanuelle Brackx, Romain Berlemont et autres

CEA has manufactured a series of Fukushima Daiichi fuel debris simulants, either with depleted uranium oxide or with hafnium oxide as a surrogate of UO2. In ex-vessel compositions resulting from an interaction between corium and concrete, the oxidic phase density becomes lighter …

High-accuracy experimental determination of photon mass attenuation coefficients of transition metals and lithium fluoride in the ultra-soft energy range

Pia Schweizer, Yves Ménesguen, Marie‐Christine Lépy, Emmanuelle Brackx et autres

In the field of quantitative X-ray analysis techniques, such as electron probe microanalysis, precise knowledge of fundamental parameters is crucial. Especially, the accurate determination of photon mass attenuation coefficients is essential to perform correct elemental quantification. While the widely used databases offer …

ELEMENTAL ANALYSIS AND RADIOACTIVITY EVALUATION OF AEROSOLS GENERATED DURING HEATING OF SIMULATED FUEL DEBRIS IN THE URASOL PROJECT

Youichi Tsubota, Laffolley Hugo, Emmanuel Porcheron, Christophe Journeau et autres

In order to safely remove fuel debris from the Fukushima Daiichi Nuclear Power Station (1F), it is necessary to quantitatively evaluate the radioactive airborne particulate generated by the cutting of nuclear fuel debris. We fabricated Uranium-bearing simulated fuel debris (SFD) with In/Ex-Vessel …
