Research Abstract |
As a bona fide extension of the exploratory work, where direct observation and active control of sodium flow dynamics have first been proposed using coherent VUV radiation, we have further extended its engineering capability to demonstrate that the proven proposition of 'transparent sodium' is practically applicable to reactor-relevant conditions, and spatial resolution of the velocity field measurement could also be improved sufficiently for comparison with large-scale simulation results. The ab-initio calculations have also been carried out. As a replacement of the emission from the induced Raman scattering, an electron-beam excited Ar excimer source has been employed, which has substantially increased the signal intensity. In addition, an imaging spectrometer has been introduced to identify the optical components from the trace graphite particles. Consequently, it was shown that the 2D liquid sodium flow velocity field could be resolved within the resolution of a few mm.
