Containment vessel dome, reactor 4, Fukushima Daiichi nuclear power plant

I assume the bolts on the yellow head cap are shown partially inserted with bolt heads 20-22" above the flange, since the head cap was removed when the fuel load had been transferred to the spent fuel pool.

Isn't the yellow dome shown in the video actually the "Head Cap" for the Mark 1 Containment? The reactor vessel and its top dome resides within the Containment, so would not be visible from the outside. I read on web the Mark 1 head cap is 67 feet in diameter.

I posted an edited 10-minute video showing the inside of three reactor buildings. The videos were made by a robot and shot on April 17th and 18th. It has the title, "First videos from inside Fukushima Daiichi Nuclear Power Plant Reactor Buildings."

This is just ridiculous and shows how irresponsible this people really are!!

If robots cab enter the building, so could A EXCAVATOR like UNMANNED machine. With SHIELDED CAMERAS properly mounted and the proper attachments it can do any job a human can!!

That "excavator" can be operated by hydraulics/air with long hoses from a nearby safe room, if electric controls are a problem ----------- this simple!

I MAINTAIN THAT, THIS IS A SIMPLE ENGINEERING PROBLEM THAT CAN BE SOLVED IN DAYS!!

is that a spy plane?

@grimlord5654 Close, it's from a "spy-helicopter," the Tarantula Hawk. You can read more about it in an article titled: "New Video From Fukushima Shows Containment Vessel Dome Amid Debris" in Forbes. I don't think YouTube allows direct links in comments, so just copy-and-paste the title into a search engine and it should bring up the article.

The dome in this video is not attached to the reactor vessel. It is set off to one side. This reactor, No 4, was empty and all the fuel is in the fuel pool. The fuel pool is overheating because of the "hot" fuel in it. It caused the explosion by producing hydrogen gas in the pool.

@doc333333 Thanks for pointing this out. You're right.
