Show me a safe design for a nuke plant and I am 100% behind it! BWR and the new ABWR are all flawed so I do not support them.n4 hours before meltdown even with the new ABWR designs.

I once made a radio feature at a UK nuclear plant (in those days they would let you tour the plant, even standing on the reactor cap). It was one of the old Magnox designs, now almost all closed. I asked the station manager what was the main difference between the various types and if there was a tradeoff between efficiency and something else. He said "time - if anything major like a LOCA goes wrong - original Magnox, you've got 45 mins for the people to fix it, AGR 20 minutes, water cooled 4 minutes". He basically said the higher the power density the less chance the opeators have to control it, it would have to be down to automation.

@Ralph - personally after Fuku I believe that ALL Mk1 BWRs should be closed immediately.

Yes

They were all about 100cm below ground level.but this is HALF......so they didn't get jack out

At Chernobyl the big concern was about groundwater contamination, at Fukushima it is a given that groundwater has been contaminated.

Seventy-three percent of Japanese do not think information provided by TEPCO about its Fukushima No. 1 nuclear power plant, is reliable, far above the 15 percent who said they thought the utility was credible, an Asahi Shimbun survey found.

Of the 34 percent who said they favor nuclear power generation, only 24 percent said they trust Tokyo Electric Power Co.

Asked the degree to which the central government is responsible for the crisis at the plant, 60 percent said the government is greatly responsible, while 34 percent said it holds some responsibility.

The latest telephone survey, conducted nationwide May 21-22, obtained responses from 2,059 randomly selected eligible voters in 3,455 households, with the exception of parts of the three quake-stricken prefectures of Iwate, Miyagi and Fukushima.

No amount of bull dozers can scrape away the groundwater that might infect the entire prefecture.

Rain likely to induce more radioactive leaks "The operator of the damaged Fukushima Daiichi nuclear power plant says it is closely monitoring contaminated water levels in the facility as heavy rain is forecast next week." www3.nhk.or.jp

Interesting how much reliable info has come out in the past couple of days about what happened, contamination levels in the sea etc etc. IAEA won't be able to say 'didn't know about that'

1 trillion counts is 1 Terabequarel.

10 to the 13 IIRC.

Your fingernail has more then 1n trillion atoms in it so the numbers can be deceiving.

@Reed - ty, that makes it seem so simple! It would be good to have something that equates @angies levels to what is being found at pant, in soil, in sea etc

Only the limited liability cap makes them possible, do we who except the liability ever get the profits?

How many millionaires left Fukushima? I am sure TEPCO shared all the profits from the plant with the residents who now have lost their homes.

Good morning all! I'm beginning to get emails in response to the message pinned above. There is some confusion as the pinned post does not make it clear which letter I was referring to. That's because what was pinned was part of a convo about the 'letter from a Fukushima mother' posted yesterday. I'll write a clearer post & hope someone will pin it to replace the 1 above

Bye @angie Hi @UKVal

Japan takes a shine to renewable energy
www.washingtonpost.com
"Only 17 of Japan’s 54 reactors are currently generating power, with 22 shut down for planned or unplanned inspections, according to the World Nuclear Association. In addition, two reactors at a quake-prone plant southwest of Tokyo were halted at the government’s request. Nine stopped automatically on the day of the earthquake, as designed, and have remained offline. And the four stricken reactors at Fukushima Daiichi will never again be used for power generation.
Because of the Fukushima crisis, Tokyo Electric Power Co. — which accounts for 27 percent of the nation’s power — has been left with major shortages."
