TEPCO Did the Water Clarity Survey of Reactor 4 Spent Fuel Pool, Says Fuku-I Worker

(UPDATE: The worker was right. I posted the TEPCO's video of the Reactor 4 SFP in my new post.)

===================================

For now, it's nothing but "hearsay" from the worker who tweets from Fukushima I Nuclear Power Plant. But it looks TEPCO is going to let us see the what the Spent Fuel Pool of Reactor 4 is like under the water pretty soon.

The worker who tweets from Fuku I says TEPCO just did a survey of water clarity in the Reactor 4 SFP, and is getting ready to video the pool with the underwater camera.

今日は4号機で東電がSFPの透明感調査したみたい。ホントは先週やるはずだったんだけどね。

It seems TEPCO measured the clarity of water in the Reactor 4 Spent Fuel Pool today. They were supposed to do it last week.

今回の調査データを基に水中遊泳カメラで見れる日も近いでし。プール内は冷却注水を止めてしばらくすれば、うっすら燃料を目視で見れるんだけどね。フロート養生する前にプール内を見たときは、思ってたほど瓦礫はなかったよいな気がする。

Based on today's data, soon we'll be able to see the pool with the underwater camera. In fact, you can vaguely discern the fuel rods with naked eyes after the water injection to the pool is stopped. When I looked at the pool before we installed the floats to protect the pool, I don't think I saw as much debris as I had expected.

手摺とかは落ちてたけど…。燃料もラックに納まってたし燃料ラックも倒れてなかったよ。いずれにしても近い内にはっきりするでし。あとマスコミ視察もオペフロまではわかんないけど、4号機の間近まではいけるかもでし。

I did see some hand rails... The fuel rods were in the fuel rack, and the rack was standing. Anyway, we'll find out soon. When the media comes for another tour, they may be able to go near Reactor 4, if not on the operation floor.

So much has been speculated about Reactor 4, in particular outside Japan where some experts and some bloggers have been saying anything from "Reactor 4 is leaning like the Tower of Pisa" to "Reactor 4 building is falling apart"; some with what they say as "proof" (statements from an insider expert in Japan), some with nothing but fantasy from looking at the photographs showing controlled removal of debris. Some still insist that there is fuel core in the RPV, though I simply don't know how it is possible when you see the lid of the Containment Vessel having neatly set aside on the operation floor, with all the equipment that was to go inside the RPV is submerged in the DS Pool.

It will be nice to at least see the spent fuel (and fuel core removed from the RPV) actually in the rack, undisturbed, as the worker claims. Load-bearing walls falling down and taking the SFP down is another matter.

The last image of the Reactor 4 SFP is from May 2011, which you can view on my post here.

sorry link broke off, see on this like lots of human activity at SFP 4

Yes, there has been a lot of human activity in the reactor building ever since November last year when they started to clean up the debris.

I am sorry but what is the DS pool?

Check this out , Plutonium dispersion from the reactors, doesnt look good for the world not just Japan.

いきなり失礼致します。
シリアに対する報道、全く違う見方があるようです。よろしければ、読んでみて下さい。

また欧米のユーザーの方々でこのような見方が出来る人はいるのでしょうか。。。?


シリアの内戦
http://tanakanews.com/120209syria.htm
田中 宇の国際ニュースより。

シリアに関する報道は殆どが歪曲されているようだ。

実際には欧米などに組織された反政府武装テロ集団と、
シリア政府軍の内戦状態のようで、
マスゴミが流しているような、政府が市民を弾圧しているのではない、
という説を田中氏は唱えている。

@シシリアン、

私も同じ間違えをしたよね。これって英語版だけど、英語でコメをするのでは? 言いたいことを全然不明でSpamにしか見えないさ。 助言で御座います:)

Hearsay: Evidence based not on a witness's personal knowledge but on another's statement not made under oath

The report indicates he himself looked at the fuel.

To the doods posting in Japanese above, Dont change the subject to Syria, this blog is all about the Radiation in Japan and Tepcos madness... Let stay on topic....

This is a great source on what is going on with the corium(s)... http://is.gd/TtB4mS

you guys should talk about reactor 3. it does not happen by accident that we dont hear anything about it

@anon at 5:04AM, it may be still "hearsay" as the worker's existence is not proven. In fact, there are many who have accused him of being a TEPCO's shill and spy. I personally do not buy that, as his tweets are "too" detailed for a TEPCO employee.

Ultraman. Sorry I didn't know where to find your email address so I'll post the link here to a journalist's analysis of a PBS TV program that tries to downplay the 'harm to human health' expected from Fukushima.
