Void fraction measurement of gas jet in sodium pool

Nishizaki, Masanori*; Tsuruoka, Hokuto*; Sugiyama, Kenichiro*; Narabayashi, Tadashi*; Ohshima, Hiroyuki

Proceedings of 17th International Conference on Nuclear Engineering (ICONE-17) (CD-ROM), 6 Pages, 2009/07

The secondary tube failure may occur due to overheating by sodium-water reaction in LMFBR steam generator. It is very important to understand the void fraction distribution in sodium pool to evaluate the overheating tube rupture. In the present study, the Ar jet of 17.3 m/s to 129.8 m/s was injected from nozzle of 3.5 mm diameter in sodium pool with 443 K and 293 K. The authors measured the void fraction without chemical reaction along the jet-center axis. As the result, the void fraction increased when the distance from the nozzle decreased. The void fraction did not change when the distance from the nozzle was blow or equal to about 1.0 mm. The void fraction in sodium was lower the that in water, it is suggested that this trend reflects the fact the surface tension of sodium is higher than that of water.

Thermal hydraulic behavior around a single heated rod with sodium-water reaction, 1

Kudo, Hideyuki*; Nishizaki, Masanori*; Sugiyama, Kenichiro*; Ohshima, Hiroyuki

no journal, , 

A fundamental experiment was performed to clarify thermal-hydraulic phenomena around a heat transfer tube of steam generator of sodium cooled fast reactor under sodium-water reaction condition. Argon gas jet with water vapor was impinged on a single heated rod surrounded by liquid sodium. Thermal hydraulic behavior on and around the rod was clarified through the measured data.

A specific phenomenon was found in fission-fragment mass distributions for nuclides around A=258 by spontaneous fission measurements. Fm256 splits into light and heavy fragments, like uranium isotopes, making two peaks in their mass distribution, whereas a sharp single peak was found in that of Fm258 which has only two more neutrons. In order to study such a specific phenomenon more widely, we performed an experiment of the multinucleon transfer fission in the O18+Es254 reaction at JAEA Tokai tandem accelerator facility.
