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.


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


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.


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.

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?

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.

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.
