French and Korean nuclear reactors won't meltdown for at least 3 days with a complete power cut-off, resisting a meltdown for as long as a week. This is enough time to restore power to reactors and prevent a meltdown.

Sadly, Japanese nuclear reactors were nowhere as meltdown resistant as French and Korean ones, Japanese are willing to trade safety for efficiency, resulting in Fukushima disaster.

So as long as you buy the Korean reactor you are fine, it won't meltdown even if a ballistic missile or a 747 dropped on it.(A new US safety requirement after 9/11). Since French tried to certify the EPR in the US but failed(Koreans succeeded in US type certification), I assume Korean reactor designs are the safest at the moment.

I would say trade safety, comfort. good life for making more money. You see it in the houses, roads, furniture, food quantity etc

Point 1. Don’t use “melt down”. This is a lie. Anybody over IQ115 must know that it was and still is a “melt through”.

Point 2. Decommissioning and construction, and research costs 10 times the amount of revenue and output of NPPs in japan. Nuclear waste storage must be maintained for 1000 years. But the cost of, and ongoing, for Fukushima Dainichi is about 100 times. I recently went to Tomioka, for research. Radiation is 6-8 times normal. I saw new houses and children playing in the soil.

Where does the...go? The moon?

3 tons of coolant per hour.

The radiation level in the No2 reactor is about 500 Sievert. The lid on the reactor was dislodged by the explosion opening it to the environment.

1mSv is one year for a normal human. I can’t count the zeros on 500 Sievets. No current technology can enter 1.2.3. So, where does the constantly flowing water go?

Japanese are willing to trade safety for efficiency

I think you mean they trade safety for profits in return for bribing politicians.

It's all very regrettable.

Weren’t the Russians conducting a similar sort of test at Chernobyl, to see what might happen? I just hope that this ‘withdraw-and-see’ is a safe game they are playing.

While I know nothing about the subject, it would seem to me that the fact that the temperature only rose one degree would seem to indicate that the fuel no longer remains in the reactor.

And heaven knows we can all trust TEPCO and Shinzo-kun

Hello Kitty, maybe, but why do they expect the temperature to keep rising? Low flame simmering effect from underneath?

1 ( +1 / -0 )

TEPCO needs to get the job done before another powerful earthquake and tsunami hits the site and carries it all away.

The melted fuel in reactors 1/2/3 melted through the reactor vessels and lies at the bottom of the concrete containment vessel.

The melted fuel is cooling but it will take tens of thousands of years before it is safe.

At Chernobyl there wasn't anything left of the reactor. Just started watching a TV mini drama about Chernobyl. HBO and Sky Atlantic.

Smart people at TEPCO would see this as an opportunity for Creating Electricity, if the water temperature rises so high, then why not use it as such - trickle feeding to maintain a constant stream of Steam, and channel it to a steam turbine. Making good of a disaster. And if a disaster arises have a damn of sea water ready to flush the reactor cooling it down... nothing new there.
