The Plasma Materials Engineering Lab studies the control and new applications of plasmas used in industry, as well as the behavior of hydrogen inside fusion reactor materials. It is hard to grasp the internal state of plasma, and to date plasma has been used largely on the basis of experience. The lab uses lasers to measure electron density and temperature in plasma, and works on optimizing plasmas such as those used as light sources for semiconductor lithography. The lab also investigates how much of the hydrogen isotopes that serve as fusion reactor fuel enters materials and how they move within them, and applies the findings to technologies for controlling hydrogen.

The Quantum Beam Applied Medical Engineering Lab studies how to use quantum beams and radiation in medicine. In cooperation with the Proton Beam Therapy Center and the Department of Medical Physics at Hokkaido University Hospital, the lab aims to realize next-generation diagnosis and treatment. The lab also actively pursues joint research with companies and advances technology development through industry-academia collaboration. The lab is run in close cooperation with the Radiological Medical Physics field of the Graduate School of Biomedical Science and Engineering, and graduate students from the Graduate School of Engineering and the Graduate School of Biomedical Science and Engineering work together with fourth-year undergraduates of the Faculty of Engineering.

The Plasma Bio-Application Engineering Lab studies low-temperature plasmas for environmental and biological applications, and high-temperature plasmas for realizing fusion reactors. The lab approaches both topics from the two sides of experiments and theoretical analysis. Divided into research groups led by individual faculty members, the lab works on measurement using interferometers and CT, plasma–material interactions, simulation, and more.

The Nuclear Reactor Engineering Lab studies reactor physics, the field concerned with understanding how neutrons behave inside nuclear reactors and how nuclear fission chain reactions proceed. The lab researches mathematical models and computational algorithms for the equations that describe the behavior of neutron populations and the phenomena in which one nucleus changes into another. It goes as far as incorporating the results into CBZ, software the lab develops in-house. The lab also applies techniques cultivated in reactor physics to fields outside nuclear power, such as thermal evaluation of radioactive waste repositories and medical applications of quantum beams.

The Nuclear Systems Safety Engineering Lab conducts research to improve the safety of current nuclear energy and to develop next-generation nuclear power systems. Its central subject is the sodium-cooled fast reactor, which uses liquid metallic sodium as its coolant. Using thermodynamic calculations and experiments, the lab examines how radioactive materials behave in a major accident, and also advances research on safety systems specific to fast reactors. The lab also works on probabilistic risk assessment that includes human behavior during accidents, and on risk assessment for small modular reactors.

The Nuclear Environmental Materials Lab focuses on research on the disposal of radioactive waste. For nuclear power to be used reliably, one condition is that radioactive waste be treated safely and securely. To predict how the materials that contain waste will change over hundreds to tens of thousands of years, the lab studies the properties of materials and the mechanisms of the reactions involved. The lab also works on research related to environmental remediation and decommissioning following the Fukushima Daiichi Nuclear Power Station accident.

Norihiro Izumi, Professor

The River and Watershed Engineering Lab studies river flow, the water cycle in river basins, and the water-related disasters connected with them. Its research fields range from river engineering and hydraulic engineering to hydrometeorology and the global water cycle. The lab also conducts research on predicting how climate change will alter the risks of heavy rain and floods, and on linking that information to disaster-prevention actions. It also carries out fieldwork in Hokkaido, such as observations at the Kushiro Wetland and snow observations in eastern Hokkaido (Doto).

Yoichi Watabe, Professor

The Geomaterial Properties Lab studies what properties soil and ground have and how they change with force, water, and temperature. The lab designation is only nominal: Professor Watabe, Professor Nishimura, and Assistant Professor Fukuda each work individually while cooperating, and share laboratories and seminars. In addition to laboratory soil tests, the lab conducts field monitoring on embankments and slopes, as well as numerical analysis. The mechanics of frozen soil, related to ground freezing methods for underground construction, is also one of the pillars of its research.

The Structural Design Engineering Lab studies infrastructure structures, including bridges. With a long history dating back to the founding of the Faculty of Engineering at Hokkaido University, the lab has mainly worked on bridges and structures built with steel materials. Its topics are broad: new bridge types, the use of new materials, design and erection methods, inspection and nondestructive measurement, maintenance, and landscape design. Students work in three teams: the Matsumoto Team, the Furukawa Team, and the Sakura Team.

Kohei Nagai, Professor

The Infrastructure Maintenance Systems Engineering Lab studies how to maintain infrastructure such as bridges and roads. Drawing on structural mechanics and knowledge of deterioration phenomena, the lab uses experiments and numerical analysis to examine how structural performance changes from design through management and renewal. In Japan, where the population is aging and shrinking and rural depopulation is advancing, the lab also works on research that uses infrastructure data and social data to propose maintenance strategies for a mature society. At present, the lab is organized around individual faculty members rather than as a single lab unit: Professor Nagai, Associate Professor Matsumoto, and Assistant Professor Furuuchi each run their own activities.
