Optical fiber distributed sensing based on Rayleigh scatter frequency domain reflectometry for Sodium leakage detection within SFR reactors

摘要

As part of the Generation IV international forum, CEA is performing research on Sodium-cooled fast neutron reactors. Liquid sodium holds many advantages such as its boiling point around 900°C, its high thermal conductivity, its ability to solidify itself after cooling. Moreover Sodium is a weak absorber of neutrons.
