#Fukushima I Nuke Plant Reactor 3 Video of Packbot Finding 1.32 Sievert/Hr Location

For more, see my previous post.

But here's the video of Packbot working at the 1.32 sievert/hr (or 1320 millisieverts/hour, or 1,320,000 microsieverts/hour) location in Reactor 3's reactor building where the human workers somehow will have to go in.

This is Part 2 of the 3 videos released by TEPCO on November 16, 2011:

This is the moment when the survey meter detected the highest radiation: 1.32 sievert/hr:

Here's Part 1 of the video, where all along the rails very high radiation is detected in several hundreds of millisieverts/hour:

Here's Part 3:

Highly interesting.
As Tepco didn't say anything about reduced radiation after swiping the rail, I think we can safely assume that it didn't change the radiation level at all.
So we can assume that the concrete already has been soaked with much contamination, even if it appears to be dry now.

The slide door in front of the equipment hatch can be seen quite well in some parts of the video.
The contamination for sure came from behind that door, probably in form of steam, condensing in the proximity of the leak. So probably the leak was in the rightmost part of the hatch, as MP 10-13 are substantially higher than MP 6-9.
So maybe the radiation at the ceiling is even higher at the floor.

I fear a bad surprise when the "carbon-based robots" slide this door open, as possibly most of the condensated radioactivity is behind it.
Then they could be basked/baked by a multiple of these 1.3 sieverts.
If I remember correctly, the radiation measured on the inner side of the equipment hatch exceeds 200 sieverts, and the workers have eventually to open the hatch.

I really don't think the PCVs will ever be accessible. It's robots all the way, or nothing.

Not that doing nothing is an option, mind you.

What are PCVs? What has to be accessed? Why do humans have to do it?

Why open anything unless genocide is the desired result?

For years after the entire complex is finally sealed under tons of absorbent shielding, the genocidal emissions already present will continue on their deadly mission.

PCV=Primary Containment Vessel

Only humans can install the gas management system which will suck the gas out of the PCV and filter it.

One could very well just drill in. But then the pleasant fantasy that these are still nuclear reactors would kinda-sorta go away, replaced by the stark reality that they are piles of radioactive debris, in dire need of "management" by means of backhoe and 'dozer.
