Ryoichi Shirato,
President
Central Research Instituteof Electric Power Industry

The Toyako Summit held in July, 2008 madepeople more aware of global environmental
problems and the reduction of GHG emissions isa truly important requirement for the electric
power industry. Meanwhile, a stable supply ofenergy has become a crucial task in view of thehike of fuel prices. Under these circumstances,
the Central Research Institute of Electric Power
Industry has been conducting a wide range ofresearch activities as a comprehensive research
institute for all energy-related fields while envisaging the likely state of electricity supply in thefuture to achieve its dual missions of "ensuring
energy security" and "approach to the global
environmental problems". In FY 2007, theresearch activities centered on five pillars, i.e.
nuclear technology, advanced maintenancetechnology, environmental and innovativetechnology, optimum energy utilization technology and social/business risk management, torespond to the actual needs in the field.
Moreover, on fulfillment of our total research
power we enhanced field crossing researchsystem and addressed the research of light water
reactors aging deterioration and global warming
issues.
The Annual Research Report 2008 outlines theprincipal research results in FY 2007. We will bevery pleased if this publication further enhances
understanding of the CRIEPI's activities on thepart of the reader and would be grateful for yourvaluable opinions.

Preface

In fiscal 2007, the CRIEPI conducted a total of 82 research projects, focusing on the achievement of three goals, i.e. “cost reduction and ensuring reliability”, “creation of integrated energyservices” and “harmonization of energy and environment”. Of these 82 projects, the results of 49
projects are compiled in this Annual Report 2008. We believe that these projects particularly
contribute to solving a number of technological and economic problems faced by electric utilities. They were selected according to the following criteria and are presented here as our principal research results.
●

Projects with a particularly high value in terms of innovation, creativity, scientific and technical achievements, economic efficiency and practicality●Projects which are timely in view of the current socioeconomic and energy situations●Projects which demonstrate the CRIEPI’s abilities, such as our general R & D capability andexpertise in basic as well as exploratory research

We will be greatly honoured if the reader finds the research results introduced in the Report
useful to facilitate the further advancement of knowledge and technology.
