Aims and Goals

Safe power generation depends on the properties of steam, and electric power is an important foundation of society. The elucidation of the thermophysical and various physiochemical properties of water, steam, and the various aqueous solution systems important to industry is indispensable in areas such as thermal and atomic power generation, plant design, and engineering applications for supercritical water.

This committee’s goal is to respond to the requirements of the industry sectors concerned by having researchers in fields such as mechanical engineering, physics, and chemistry work closely together to investigate the various properties of water, steam, and aqueous solution systems, compiling data in easy-to-use formats.

The committee also serves the role of the Japan committee of the International Association for the Properties of Water and Steam (IAPWS), which has a 30-year history, fully cooperating in drafting international standards for relevant fields and promoting their adoption.

Research Themes

1. Research fields that contribute to improvements in the performance of power plants and other systems that use energy and machinery for industrial processes
 (1) Contributing to the optimal design of and improvements in the performance of power plants and other systems that use energy and machinery for industrial processes that are important to industry through development of and research into simple, practical, and new methods of and software for computing numerical data concerning the thermophysical properties of water, steam, and various aqueous solution systems
 (2) Basic research from the perspectives of thermodynamics, physical chemistry, water chemistry, etc., into trace components and other elements contained in the light water that is the working fluid for power plants
 (3) Development of technology to directly monitor the quality of water in the steam circulation systems of power plants, development of mechanisms for concentrating and condensing trace corrosive impurities, and development of initial condensation and deposition mechanisms in steam turbines and other equipment
 (4) Study of and research into technological development trends in Japan and overseas related to the technologies of thermal and atomic power generation; to the constituent equipment of such power generation plants, such as boilers, turbines, and heat exchange devices; and to global environmental issues
2. Research fields that contribute to technology that uses supercritical water to reduce the load on the environment and to develop new materials
 (1) Study of and research into technological development and research trends in Japan and overseas concerning the decomposition of environmental pollutants (focusing on significant increases of solubility and velocity constant in supercritical water) and development of new materials, such as high molecular compounds
 (2) Basic research to clarify the association between hydrothermal and supercritical water reactions and the structure, physiochemical behavior, and thermophysical properties of supercritical water
3. Research sectors carrying out the formularization of data on the physical properties of aqueous electrolyte solutions and saltwater associated with the desalination of seawater
 (1) Basic research to gather the required numerical data on the thermophysical properties of model seawater (aqueous electrolyte solutions), so that seawater can be used to produce large quantities of water—which is indispensable not only to power generation but also for life in general and for the production of foodstuffs through farming and the raising of livestock—and the use of this basic research to formularize an equation of state and a viscosity coefficient for new aqueous electrolyte solutions so that the formula can be used as a function not only for the temperature and pressure but also for salinity
