The Ministry of Economy, Trade and Industry has redrafted the nation's national long-term energy plan by adding words that place more emphasis on nuclear power, it was learned Friday.

Nuclear power is an "important base-load power source that serves as a foundation" for the stability of Japan's energy supply, the new draft says. The previous version just said it is an "important base-load power source."

Base-load power refers to sources of electricity that are cheap, stable and usable on a continuous basis.
