Ayumi ITOH
I have researched to investigate the severe accident phonomena at Fukushima Daiichi Nuclear Power Station, especially the core degradation and fuel debris formation mechanism by experimenal and computational way. Main experimental works are in-situ investigation of materials interaction at the synchrotron radiation facility, and quenching of high-temperature liquid alloys under severe accident condition. Computational works are the mass and heat transfer analysis coupling with thermodyanmic data. Recently, I am trying the ab-initio calculation for the fuel materials. I am very happy to join Nakase lab. Let's enjoy the research life with us!

Group Leader / Japan Atomic Energy Agency
Kenji NISHIHARA
Our team is actively engaged in the development of diverse assessment codes under the banner of NMB. These codes empower individuals to quantify potential future nuclear power generation scenarios through various choices. This fosters an environment where informed discussions are grounded in numerical data. You can find further information on NMB framework research topics at https://nmb-code.jp/.
Moreover, my regular place of work is the Japan Atomic Energy Agency located in Tokai-mura, Ibaraki Prefecture. Here, I am dedicated to research concerning the accelerator-driven nuclear transmutation system (ADS). Outside of my professional commitments, I enjoy gardening at my Tokai-mura residence.
