It is the fundamental role of electric utilities to ensure stable supply of quality and inexpensive electricity by simultaneously achieving the 3Es—“Energy Security,” “Environmental Conservation,” and “Economy”—as set forth in the Basic Law on Energy Policy.Electric utilities will promote CO2 emission reduction measures to attain simultaneous achievement of the 3Es, thereby contributing to building a low-carbon society.
→ It is important to appropriately take into account not only environmental aspects, but also energy security and economy.

Japan has a fragile energy supply-and-demand structure, with few natural resources, a low energy self-sufficiency rate. To meet electricity demand that has been steadily increasing in these tens of years, continued action is taken to ensure stable supply and deal with the problem of global warming through the “best mix,” by shifting the focus of power source development from hydro through large-capacity thermal to nuclear power generation.

○ It is aimed that nuclear power generation either maintain or increase the current supplied energy level - 30 to 40% of the generated output - beyond 2030.○ Utilization of materials such as plutonium and uranium recovered through spent fuel reprocessing will be included in the basic policies.○ Commercial adoption of the fast breeder reactor will begin in 2050.

It is very important for Japan to establish the nuclear fuel cycle project due to its poor energy self-sufficiency rate, so as to further improve the features of nuclear power generation and allow for a long-term stable electricity supply.For example, Japan has created basic policies to continue promoting nuclear power generation and to steadily advance the nuclear fuel cycle.Electric utilities are promoting the use of nuclear energy based on these basic policies.

On the major premise of public acceptance and regional coexistence, all utilities efforts will be put into maximizing the potential of existing nuclear power stations, promoting new plant construction and replacement, and establishing the nuclear fuel cycle to achieve the goal of promoting nuclear power generation.To contribute to maintaining and expanding the world’s nuclear energy, it is important to gain international trust by continuing stable operation of domestic nuclear power stations. We will then make international contributions, taking advantage of the features of Japan’s technologies.

○ Components and structures with safety functions will be subjected to integrity assessment (aging management engineering assessment) before they have been in operation for 30 years, and will assume they will be used for 60 years. Based on this assessment, a “long-term maintenance plan” will be mapped out, putting together new measures to be added to maintenance management activities.
○ Under the new inspection system, a “long-term maintenance management policy” (equivalent to a long-term maintenance plan” will be developed and described in the Technical Specifications for the approval of the national government.

○ Since the construction of a nuclear power station takes a long time from its planning to the start of operations, it is important to promote replacement and new construction smoothly.
○ To do so, it is necessary to develop a mid/long-term business environment to allow for investment in nuclear power generation.
