...Concern about aging reactors has been growing because the three units at the Fukushima Dai-ichi plant in northeastern Japan that went into meltdown following the tsunami in March were built starting in 1967. Among other reactors at least 40 years old are those at the Tsuruga and Mihama plants in central Japan, which were built starting in 1970.
Many more of the 54 reactors in Japan will reach the 40-year mark in the near future, though some were built only a few years ago.
The government said Friday that it plans to introduce legislation in the coming months to require reactors to stop running after 40 years...The future of Japan's nuclear policy remains under review. Some people are worried about radiation in the food and water, as well as the health of children, who are more at risk than are adults to sicknesses from radiation exposure.
