1. Outline of Research Activities
To struggle “ensuring energy security and responding to global environmental problems”, we deﬁne "nuclear technology", "stable electric power supply technology" and "environment and energy utilization technology" as three basic principles to conduct technical development at the supply sides for maintenance andimprovement of power supplying force as well as technical development leading to low carbon society
through high effective energy utilization at demand sides, biomass utilization, use of renewable energy andothers.
Among the numerous research subjects of CRIEPI, we deﬁne “Project subjects”, for which there is an extremely high need by the electric power industry and the society, for which timely achievements and utilization are required. Research activities on these project subjects are surging ahead interdisciplinary under thelateral promotion organization combining eight professional research laboratories* of CRIEPI. Anothergroup of research subjects is called “base technology subjects” where strenuous efforts are being made to
develop and improve elemental technologies for future application. Those under development making thebest use of the special expertise of the eight excellent laboratories include technologies to maintain and passdown, technologies to be further developed and technologies of which new research development is required, such as highly efﬁcient energy utilization on the user side.
In FY 2009, intensive research activities were conducted for 37 project subjects and 35 base technology
subjects as shown by the "CRIEPIʼs R&D Portfolio in FY2009" on the opposite page. There was one "general project" on the plant life management of light water reactors. This research project was given priority
status in view of the aging of existing light water reactors and was promoted across various research ﬁelds.
The principal research results in FY 2009 are described in Chapter 2 by each subject in the case of projectsubjects and by each laboratory in the case of base technology subjects along with the objectives of eachresearch subjects.New research facilities were installed to support research activities.
These includes an "updated large capacity short-circuit test device", "light water reactor materials analysis
station", "piping corrosion wastage evaluation test device" and "enhanced large computer system for scientiﬁc computation". These facilities/equipments are brieﬂy described in Chapter 3. The overall business activities of the CRIEPI are compiled in Chapter 4.
