Department of Quantum Science and Energy Engineering, Graduate School of Engineering Tohoku University

Message from the Head of the Department The Department of Quantum Science and Energy Engineering was established as a general engineering field of study that assumes the role of developing the science and skills related to nuclear power generation and radiation applications. As trail-blazing human resources, the graduates of this Program with advanced specialized knowledge and initiative are the underpinnings of energy supply and societal infrastructures, and at times have acted as the driving force of rapid economic growth and this industry's development. In response to the times and to society's demands, our field of nuclear engineering has expanded into "quantum science and energy" studies; and we are pursuing engineering applications of physical phenomena at the micro level, as well as developing leading-edge research across a broad spectrum from environment/energy fields to medical engineering.

Professor Yuichi Niibori Head of the department

Recovery from the Fukushima disaster is still ongoing. Now, more than ever, there is a need for people who have advanced skills and insights on nuclear energy; as well as an outlook for the future. As educators, the roles that we need to fulfill and the responsibilities that we have are enormous. On the other hand, the development and evolution of "quantum science and energy engineering" as a discipline that can meet the new demands of the times and society such as applications in the medical and environmental and nuclear fusion fields are attracting attention and expectations.

Most of the security, safety, conveniences, comforts, abundances and pleasures in daily life and society are brought about by rapid advances in science and technology. Science and technology support the development of economic industries, create a wealth of value and affect our daily lives. It is not an exaggeration to say that even within science and technology, quantum science that deals with physical phenomena on a micro level such as electrons, atomic nuclei and atoms is the "cornerstone" of modern science. By understanding and delving into the world of quantum studies which began in the early twentieth century, we have unlocked many mysteries and have acquired various knowledge and information in the process. There are developments in accessible applications of quantum science and energy engineering in the energy, medical, environmental and other fields. Of them, very well-known examples include the nuclear fission reactor which utilizes and controls nuclear reactions to extract thermal energy. As an energy source in the future, another example is the nuclear fusion reactor which is being cumulatively researched and experimented on through global collaborative efforts. Depending heavily on resources from overseas, it is said that Japan has a mere 4% self-sufficiency rate in energy. Maintaining energy security, which entails the continuous and stable securement of sufficient energy at reasonable prices, remains an enormous challenge. Therefore, we think that nuclear energy and the nuclear fuel cycle that meets sustainability issues are both essential. Furthermore, with the goals of reducing greenhouse gases and moving away from fossil fuel dependence, nuclear energy which does not emit carbon dioxide during its production process along with other renewable energy sources play a significant role in a stable power supply. However, to be able to use nuclear energy in a safe and stable manner, avoiding an accident such as the Fukushima Daiichi Nuclear Power Plant Disaster at all costs is a precondition. As a university that has undertaken “quantum science and energy engineering” research and education for over half a century and has turned out numerous human resources for the nuclear power sector, we researchers and educators are looking at this disaster squarely. The results of our examination and selfsearching on the matter are reflected in our new subjects for research and education systems. “The lack of commanding a view over the complete picture” has been given as one of the reasons for the Fukushima Daiichi disaster. We have now begun training human resources who can be held accountable to society - engineers and researchers who are not only highly knowledgeable in radiation, radioactivity, nuclear reactors and others, but are also highly ethical and possess a wide vision, critical thinking skills and communication skills. Recovery from the Fukushima disaster is still ongoing. Now, more than ever, there is a need for people who have advanced skills and insights on nuclear energy; as well as an outlook for the future. As educators, the roles that we need to fulfill and the responsibilities that we have are enormous. On the other hand, the development and evolution of "quantum science and energy engineering" as a discipline that can meet the new demands of the times and society such as applications in the medical and environmental and nuclear fusion fields are attracting attention and expectations. "Converting 'nuclear engineering' into power that will broaden the future" - we who aim to create new science and technologies have this is as our mantra.

- Research of Advanced Nuclear Fission System Nuclear fission systems (nuclear reactors) are the important electrical energy source which support Japanese infrastructure. They also have great potentials as the low-environmental-loaded and long-life energy source and the seeds of the innovative research field such as the applications to nuclear transmutation, deep space utilization and hydrogen production. Our laboratory tackles “Advanced Nuclear Fission System” which supports present and future life.

Research and Development (R&D) of Advanced Nuclear Fission System Study of Nuclear Transmutation Study of Accelerator-Driven System (ADS) Study of Various Nuclear Fuel Cycle Scenarios Study of Advanced Reactor such as Small Reactor and Space Reactor

The disposal of high-level radioactive waste (HLW) is the unavoidable problem to utilize nuclear energy. To solve this problem, we address the research and development of nuclear transmutation technology. Nuclear transmutation technology is the method to transmute high-toxic and longlife nuclides included in HLW into short-life and stable nuclides by nuclear reaction.

We are studying from the viewpoint of thermofluid dynamics in order to advance a current nuclear system and to realize a fast reactor and a fusion reactor. Turbulent enhancement of mass transfer from wall: pipe-wall thinning in NPP Pipe wall thinning due to flow-accelerated corrosion (FAC) is one of the influential phenomena in a nuclear power plant (NPP). We are approaching from flow field and mass transfer points of view.

R&D of a fusion liquid blanket using Flibe A Flibe blanket has several merits such as being simple due to the dual roles of FLibe as tritium breeder and coolant, while its heat transfer performance has to be enhanced. We are developing the blanket in which both heat transfer enhancement and high functionality are achieved.

Nuclide Separation Technology of High-level Liquid Waste and Medical Application Method of Separated Nuclide

One of the most important problem in nuclear fuel cycle is minimizing amount and reducing radiotoxicity of high-level liquid waste (HLLW) generated from spent fuel reprocessing. In our laboratory, to solve the problems, we focus on nuclide separation by column chromatography method and we carry out research and development of novel adsorbent having high selectivity for each nuclide such as Cs, Sr, platinum group metals (PGMs) and minor actinide (MA). Furthermore, we make experimental study on novel purification process of radioisotope separated from HLLW to use for internal irradiation therapy for cancer.

Dynamitron The Dynamitron accelerator is a single-ended type with a Schenkel type highvoltage power supply. The accelerator was provided with a high-current duoplasmatron ion source, which can generate hydrogen, deuterium, or helium ion beams. Characterization of the spatial distribution of elements in a specimen is an important technique for various fields. A submillimeter beam system and a microbeam system were installed in 1998 and 2002, respectively, and have been used in several different fields. The microbeam system has been applied to simultaneous in-air/in-vacuum particle-induced X-ray emission, Rutherford backscattering spectroscopy, secondary electron, scanning transmission ion microscopy analyses, and micron-three-dimensional computed tomography. In 2014, another microbeam line was developed. It is dedicated to chemical state mapping, i.e., a Von Hamos X-ray spectrometer with a charge-coupled device camera. As well as beam line, the accelerator has been upgraded to meet the requirements from users.
