Japan plans to scrap nuclear plants after 40 years

By Associated Press

POSTED:



TOKYO » Japan says it will soon require atomic reactors to be shut down after 40 years of use to improve safety following the nuclear crisis set off by last year's tsunami.

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. Japanese media reported that the law may include loopholes to allow some old nuclear reactors to keep running if their safety is confirmed with tests.

The proposal could be similar to the law in the U.S., which grants 40-year licenses and allows for 20-year extensions. Such renewals have been granted to 66 of 104 U.S. nuclear reactors. That process has been so routine that many in the industry are already planning for additional license extensions that could push the plants to operate for 80 years or even 100.

Japan does not currently have a limit on years of operation. It had planned to expand nuclear power before the meltdown, but has since ordered reactors undergoing routine inspections to undergo new tests and get community approval before they can be restarted. The new restrictions mean that only six Japanese reactors are currently running.

The Asahi newspaper reported Saturday Japan is likely to face a power shortage if it carries out the 40-year rule, which barring loopholes would force 18 more reactors to shut down by 2020, and another 18 by 2030.

The government has already decided to scrap six reactors at Fukushima Dai-ichi, where backup generators, some of them in basements, were destroyed by the March 11 tsunami -- setting off the world's worst nuclear crisis since Chernobyl. The government has said it will take 40 years to fully decommission the plant.

It is unclear whether the age of the reactors was related to the nuclear crisis. The location of the generators, absence of alternative backup power and inadequate venting are believed to be more direct causes, but some critics have said the Fukushima plant showed signs of age, such as cracks in piping and walls.

Promising that nuclear plants may be gone in about four decades may help the government gain public support for getting more reactors running again.

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.

This is an unnecessary over reaction. The Fukushima nuclear power plant was an outdated, obsolete 60 year old designed plant that was about to be closed down just months the tsunami hit. Unlike the old designs, which need electricity to shut down, the modern plants can shut down safely with no electricity backup. Fear of nuclear is affecting Hawaii's electricity prices, since our oil prices have gone up as a result of increased demand in Japan. Ignorance and fear wins the day.

Fukushima hasn't aided the cause and is likely to cap demand for some time. A lot of the existing generation capacity is aged and may well not be replaced, while new facilities are being delayed and reconsidered. I've never liked nuclear nor bought into the "low cost" argument. The as-of-yet unsolved permanent waste disposal, decommissioning costs that are never factored into the front-end project cost, massive cost overruns during construction, and the potential we have witnissed for serious disaster make nuclear a no go.

Mount Yucca is a reasonable solution to the nuclear waste problem. Unfortunately, fear and ignorance allowed it to stay closed and go unused.

The Nuclear Regulatory Agency is controlled by the nuclear industry. Because of this leaking aged plants are having their licenses renewed via rubber stamp. Expect the same to happen in Japan.

New pellet technology is MUCH safer. But that said, Japan will be on diesel and coal again.

Too late after using Mox fuel rods at F-shima. What is the half life of that Plutonium-239? Oh yeah, 24,100 years in the ground and groundwater so close to Tokyo. Shame.

Replace the bad old uranium reactor power plants with thorium reactor power plants... cleaner by far and more efficient... and nuclear weapons can not be made from thorium... and ... there is a lot more thorium than uranium.
