    It is the obligation that all of us have in bringing engineering systems that are safe, reliable, and that will build public confidence in the technology. This talk is not about technology, it is about the obligations we have as engineers. Engineers and engineering managers need a questioning attitude, the cornerstone of a good safety culture. Our greatest accomplishments have sometimes come as the result of things we most sincerely wish had never happened -- accidents. Accidents do play a role in generating improvements in regulatory and industry performance. But they are not worth their cost. As engineers, we have the obligation to learn from our mistakes and not to hide from our failures. If we want to truly change the world, to protect the global environment, to raise the standard of living for people in poverty, we must be willing to learn what it means to have a safety culture.

    Nuclear Power Plants are considered as the main solution to improve the environmental issues because they exhaust very few CO2, NOX and SOX. Therefore, people are calling the nuclear renaissance. However, there are still anti-nuke people in the world. Their main fear is the radiation exposure. In 1992, OECD/NEA organized ISOE (Information System on Occupational Exposure) Committee to improve the technology for the nuclear power plant to reduce the radiation exposure and IAEA joined as the joint secretariats. Right now 29 countries join ISOE committee whose members are composed by the regulatory bodies and the utilities. This committee is collecting the golden nugget technology how to reduce the radiation exposure and inform to all nuclear power plants to improve their plant condition. There are some examples and graphs to explain these technologies.

    With respect to the state-wide energy use, there might be found a paradox that more electrification apparently causes more energy losses by the power generation loss. This easily leads to a misunderstanding. Energy end-users need energy benefits, but neither city gas/oil nor electricity for the final energy consumption. They can have the two ways to heat an object, fuel combustion generating unavailable energy and heat pump use adding available energy (exergy, actually power) to the environmental energy or waste heat. And mechanical power demand, e.g. driving vehicles can be supplied from the electric power system of the highest efficiency. Such highly efficient use of energy brings more electrification. This paradox lies in the insufficient understanding of energy use science. The author considers the overall optimization for the efficient use of energy.

    In order to combat global warming, attention has been increasingly shifting towards nuclear and renewable energy such as wind and solar power generation as feasible power resource alternatives. The electric power suppliers of Japan are aiming to increase the amount of nuclear and non-fossil fuel power generation by over 50% of total power generation by 2020. However, this does not translate into the complete eradication of the traditional model as the remaining half will still depend on fossil fuel-based thermal power generation. Given these circumstances, Japan has aggressively implemented further measures to enhance the efficiency of thermal power generation.

    Mitsubishi Heavy Industries, Ltd. (MHI) developed a 1100°C class D series gas turbine in the 1980s and constructed the world’s first successful large-scale combined cycle power plant. Since then, MHI has developed the F and G series gas turbines with higher turbine inlet temperature and has delivered these units worldwide accumulating successful commercial operations. These gas turbines are constantly improved, adding to their successful operation. MHI is currently participating in a Japanese National Project to promote the development of component technology for the next generation 1700°C class gas turbine. The thermal efficiency will be improved significantly with this new technology by raising the turbine inlet temperature and the pressure ratio. MHI recently developed a 1600°C class J series gas turbine utilizing some of the technologies developed in the National Project. This paper discusses the history and the evolution of MHI large frame gas turbine for power generation and the activities currently in progress for an environmentally friendly technology in the future.

    This paper presents activities towards the promotion of environmentally compatible thermal power plants. Activities include a study for improving the efficiency of steam turbines using large-scale testing equipment, and the development of a large-scale indirect hydrogen cooled generator. The development of an advanced ultra super critical system (A-USC) to increase plant efficiency is also presented. Finally, activities to develop a post combustion carbon dioxide capture system from flue gas to realize a zero-emission thermal power plant are presented.

    Environmental issues are becoming increasingly apparent on a global scale with rising CO2 levels generated by a rapidly growing human population. At the same time, as pointed out by the Club of Rome in 1972, this population growth is also accelerating consumption of natural resources. In relation to CO2 reduction, a two-prong approach is being taken to reduce CO2 from the energy generation side and also from consumption side. On the generation side, we are concentrating on the proliferation of low-carbon energy such as nuclear and renewable energies, as well as increasing plant efficiency in thermal power generation along with Carbon-Capture-and-Storage (CCS) technologies. On the consumption side, efficient energy storage devices such as batteries are becoming a key issue in effective energy utilization together with the ongoing challenge towards ever greater efficiency of motors and inverters. This paper discusses current research activities in power generation technologies.
