Wang Kai (D2), Department of Nuclear Engineering and Management, won Best paper Award at the 26th International Conference on Nuclear Engineering (ICONE 26)

On 27th July 2018, Wang Kai (D2), Department of Nuclear Engineering and Management, won the Icone26-Best paper Award at the 26th International Conference on Nuclear Engineering (ICONE 26).

<Name of award and short explanation about the award>

Icone26-Best paper

Icone26 is short for International conference on nuclear engineering, and is one of the most widely attended conferences in nuclear field. This best paper rewords go to the selected students from all the students applied. This rewards intends to courage those who did a good job in their research. In Japan/Asia region, 5 papers were selected and in total 20 papers were selected out of hundreds of papers received.

Title : Preliminary Research on the Oxidation Effect of the Carbon Steel Plate of Downward Facing Pool Boiling by Two-Dimensional Image

CHF is the utmost part because it limits the upper threshold of the cooling effect in the external reactor vessel cooling (IVR-ERVC). This CHF experiment here used carbon steel plate on a downward face. And the growing tendency of the CHF with oxidation time was found. It was found that the more the oxidization was, the fewer bubbles were generated and the bigger the CHF was. We found that this increase is due to the change in the nucleation site density, not the wettability. Which is important in the knowing mechanism of CHF.

< Your impression & future plan>
I am really very happy to be awarded. I would like to thank Prof. Koji Okamoto and Prof. Nejdet Erkan for their guidance and support for this conference. Also I would like to thank JSME for selecting me as a qualified student and covered my hotel expenses. And about future plan, more research including experiment and numerical simulation should be carried out to study the effect on the oxidation effect to improve the safety margin of IVR-ERVC. And next year it will be held in Japan, we will work hard and share more of our research with others.
