Why is nuclear power generation necessary?
Just imagine what it would be like without electricity. The Earth's energy resources,including fossil fuels, are not infinite. Should we run out of petroleum and natural gascompletely, we would have to give up our current convenient and comfortable lifestyle,which is made possible through electricity.
In order to ensure a stable and sustainable supply of energy, we need to attain a well-balanced energy source mix, and combine nuclear power, thermal power, hydraulicpower, wind power and solar power to make the most of each type of energy source.Nuclear power is a particularly stable source of energy which can produce a largeamount of electricity and requires less fuel.

Thermal power plants generate electricity by burning fossil fuels such as petroleum,coal and natural gas. This combustion process is the source of CO 2 emissions, whichcauses global warming.Nuclear power generation, in contrast, harnesses the heat energy produced by nuclearfission. Because there is no combustion involved in the process, nuclear powergeneration does not emit CO 2 in principle. (See the chart below.)Furthermore, indirect CO 2 emissions from processes such as mining/transportation offuels and development/operation of power stations are miniscule. While a natural gas-fired combined cycle plant, which is the most efficient power generation option, emitsapproximately 474g of CO 2 to generate 1kWh of electricity, a nuclear power plant emitsonly about 20g of CO 2 and can generate the same amount of electricity.In short, nuclear power generation is an eco-friendly way of generating electricity fromthe viewpoint of the prevention of global warming.

* CO 2 emissions from nuclear power include reprocess of spent fuel, plutoniumthermal use, management of High-level radioactive waste, etc.

Since 1957, when we embarked on the development of nuclear power technologies, wehave been involved in various nuclear power projects such as the development ofresearch reactors, prototype reactors and commercial reactors. In accumulatingexperience through such accomplishments, we have always made it our top priority toestablish the best possible safety and reliability for the equipment used in nuclear powerplants. We handle our products with the utmost care, and ship them only after theirsafety and reliability are confirmed following a series of qualitative inspections.Hitachi's nuclear power business has also started new initiatives towards globalization.In 2007, we established 'Hitachi-GE Nuclear Energy, Ltd.' and 'GE-Hitachi Nuclear
Energy LLC.' jointly with GE, combining resources with the US-based company. We arecommitted to providing our advanced technologies, which we have cultivated fordecades to help the global market.
