Research Groups

Research Institute of Science for Safety and Sustainability has 7
research groups. Followings are the outline of each group.

RISS Members

Risk Assessment Strategy Group

This group is chiefly examining how to assess risks associated with chemical substances and nanomaterials with their management taken into account (= strategy). The study in the group regarding the risk associated with nanomaterials consists of development of efficient hazard assessment methods in the regulatory context, and development of a simple and quick hazard assessment method for voluntary safety management. Regarding the risk associated with chemical substances and their combined exposure, methodologies for estimating both human health risk and ecological risk have been developed and applied to actual problems.

Environmental Exposure Modeling Group

This group is developing a technology for exposure assessment, the core point of assessing the risks of chemical substances to humans and ecosystems. It is also conducting research centering on the development of exposure assessment models in the atmospheric environment, indoor environment, rivers and oceans. Exposure and risk assessments using these models are being made in cooperation with other groups so that the results of such efforts can be utilized for policies for the management of chemical substances.

Emission and Exposure Analysis Group

We conduct human health and ecological risk assessment of new and alternative substances and complex mixtures. This group’s major research activities are the development of methods for estimating the physical property, emissions into the environment, exposure and risk to humans and living organisms. We also conduct risk assessment for natural disaster and for accident of advanced technologies. We focus on the development of framework of advanced risk assessment of chemical substances used for energy carrier of hydrogen, and the risk trade-off analysis on the countermeasures of radiation risk reduction.

Explosion Safety Research Group

Our group has conducted extensive study from basic researches to applied ones on explosion safety, including clarification of a mechanism for initiation and explosion phenomenon for high-energy materials such as explosives and development of a technology to ensure the safety of such materials, a risk assessment technology, a mitigation technology of explosion effects, and novel technologies to utilize high-energy materials effectively.
We have actively implemented technical assistance in response to governmental requirements, and conducted a large-scale field explosion tests.
Such outcome has been reflected on establishment of the technical criterion for safe handling of high-energy materials not only in Japan but also abroad through such a proposal of test methods in the United Nations conferences. We have been contributing to the realization of safe and secure society.

Industrial Safety and Physical Risk Analysis Group

In order to utilize the excellent properties of the materials with energy, combustible gases such as hydrogen, new energy carriers, new mildly flammable refrigerants, and explosives are to prevent the occurrence of accidents by a technique for controlling them appropriately, also, there is a need to take advantage while ensuring safety by technology to reduce the damage in case of any chance of an accident. For this purpose, in order to achieve a safe and secure society through voluntary managed industrial safety technology, 1) safe use of high-pressure gas, 2) safe use of explosives, 3) focusing on research related to industrial safety, we are conducting research to meet the needs of government and society in fire and explosion safety.

Advanced LCA Research Group

Understanding the consequential effects on environment, economy and society by the implementation of new technologies plays an important role to discuss their diffusion strategies and design their promotion plan.

Life cycle assessment (LCA) is a methodology for assessing the environmental aspects and potential impacts associated with a product or service during its life cycle. Advanced LCA Research Group sets the LCA methodologies and life cycle thinking as the core of our research. By combining the core with security of minerals and energy systems analysis, we are conducting researches on technology assessments by the implementation of new technologies such as developing methods to evaluate the consequential effects on sustainability pillars and designing social system for a sustainable society.

Energy Systems Analysis and Policy Study Group

Energy systems analysis by means of mathematical models, the energy management system of residential buildings in view of resiliency, the evaluation and analysis of energy conservation in the commercial sector, and the estimation of global sustainability indices considering energy and resources are the principal research subjects of this group. Through these studies ranging from a local level to a global level, together with official and non-official collaborative activities, we try to give insights into the optimal energy systems that attain the quadruple aims of Energy Security, Economic Efficiency, Environment and Safety (3E+S).

Research Laboratory for IDEA

We established the Research Laboratory for IDEA on April 1 2017 at Research Institute of Science for Safety and Sustainability, Department of Energy and Environment, AIST. We will build International cooperation and evaluate new materials and new technology development based on the IDEA (Inventory Database for Environmental Analysis).
