Topic: Nuclear crisis in Japan at level 7

[Chew]

Evelyn Mervine, who conducted a series of interviews with her nuclear engineer father during the height of the crisis, is planning on having a follow-up interview with him and she is soliciting questions to ask him: Plans for a One Year Fukushima Update Interview

A tool equipped with a tiny video camera, a thermometer, a dosimeter and a water gauge was used to assess damage inside the number two reactor's containment chamber for the second time since the tsunami swept into the Fukushima Daiichi plant, a year ago.

The data shows the damage from the disaster is so severe the plant operator will have to develop special equipment and technology to tolerate the harsh environment, and decommission the plant. The process is expected to last decades.

...

Plant officials previously said more than half of the melted fuel had breached the core and dropped to the floor of the primary containment vessel, some of it splashing against the wall or the floor

One of Japan's crippled nuclear reactors has ... much less water to cool it than officials estimated.

Does it still need water cooling?  I don't know the specific power history of the Fukushima reactors, but 1 year after a normal reactor shutdown, you'd expect them to start moving spent fuel from cooling ponds to dry casks, because the decay heat is diminishing.

It's good that they have this extra information, though.

5 to 6 years is how long our spent fuel is in the pools before moved to other pools where they will stay for over 15 years before moving to a dry storage.

There are a lot of residual effect in the spent fuel, and with a meltdown such as there is in these plants there is even a risk of the fuel getting critical. Water both cools and inhibits neutron flow, so the more the merrier.

For the most at risk fuel ponds, they will have to build a huge structure to mount a new crane on, then they can try and move the fuel rod assemblies.   As long as they don't have a big earthquake before then ...

God Speed

Japan has given final approval for the restart of two nuclear reactors, a move that will end a total shutdown of the atomic power sector caused by safety fears raised by last year’s crisis at the Fukushima Daiichi plant.

     Oh the irony

[♫♪ FX ♪♫]

      In totally unrelated news, another reactor in Japan has more than likely bit the dust.  And it wasn't from an earthquake or a tsunami.

HAHAHAHAHAHAHAHA!! First you post this:

  I try to avoid internet entanglements.   I got enough drama in the real world, I don't need trouble from people I never met yet.

Then you post this:

      In totally unrelated news, another reactor in Japan has more than likely bit the dust.  And it wasn't from an earthquake or a tsunami.

You're like the most obvious troll ever.

     As for unrelated reactor news,

See?  When there are actual real problems afoot, internet conflicts don't seem that important.  Hell, I consider the internet for fun not war.  But each to his own I guess.

Honestly, I'm usually a lot less confrontational. But this Hanson guy both intrigues and enrages me for some reason. I dismiss most cranks, but this guys hits a nerve with me that I can't explain.

Panda, the last two posts between FX and myself could have stayed in the other thread. They don't really apply to this thread. Is it possible to fix it?

Well, I moved the one where you're quoting FX because you're responding to his article about Japan, and the one after that because he's responding to your response. If you were making a reference that only makes sense in the 9/11 conspiracy thread, it totally went over my head.
