Associate Professor / Kenta MURAKAMI
As the leader of the laboratory, Murakami sensei has the good ability as Sun Tzu said on The Art of War: “The Commander stands for the virtues of wisdom, sincerity, benevolence, courage, and strictness”. Those abilities with a strong relationship with both national and international nuclear industries make the study and research activities can be done smoothly and full of fun.

Research Content

The scope of material and maintenology research is very broad ranging from atomic material characteristics to management issues especially related to how to select the right materials, understanding the material degradation, system reliability and preparing the good maintenance strategy for safe and economic NPP operation as well as the part of mitigation if the accident occurs. Material degradation characteristics caused by thermal, chemical, radiation ageing, including physical shock degradation are studied by several instruments such as using a particle accelerator, nano-indenter, XRD, FIB, SEM/TEM, etc. Such kinds of computer simulation are also used as part of the deterministic and probabilistic assessment of SSCs reliability as an effort to find new data and develop more advanced theories, techniques, and methods.

A Day in the Lab

As our motto "fun learning & smart working", our working environment is very flexible, seems relaxed but serious, full of jokes and laughter with an environment that is even closer than just as friends. In general, each student has diverse research topics that cause differences in daily routines. however, besides weekly seminars, usually before 9 o'clock in the morning is began with a light discussion accompanied by a glass of coffee. Each student usually announces what experiments they will do on that day or in the next few days so that those who also want to learn can join in and become an observer. With this method, we can develop and transfer our skills and knowledge easily. A number of activities outside the lab are also often done to support the learning process and make relations between Laboratory members become tighter.
