The neutron transport in nuclear fuels depends on the crystalline structure of materials when neutron energies lie below a few eV. For that purpose, the theoretical formalism that describes the neutron elastic and inelastic scatterings by crystals ha

Gas detection in sodium cooled fast reactors: determination of a transfer function

Autor: P. Filliatre, C. Ding, L. Desgranges

Publikováno v: EPJ Web of Conferences, Vol 253, p 05002 (2021)

To keep the dependability of Sodium Cooled Fast Reactor, the “clean sodium concept” is demanded, which means that the sodium is free from contamination. The release of fission products is searched for by a contamination measuring system. We need

Conception of delayed neutron detector blocks in a sodium cooled fast reactor

Autor: P. Filliatre, C. Ding, Romain Coulon, L. Desgranges, C. Jammes

Publikováno v: Nuclear Engineering and Design. 371:110933

The primary vessel of a sodium-cooled fast neutron reactor (SFR) must remain free of any contaminant released by a cladding failure in a fuel assembly. A comprehensive detection system of cladding failures has then to be considered right from the beg
