If I'm not wrong, the whole Chernobyl Power Plant is inactive... It was shut down due to concerns over stability of the plant itself...

After reactor #4 exploded and the clean up crews contained what they could, the remaining three reactors were kept running, according to Wikipedia's article, due to an energy shortage in the country :Link.

So the breakdown of each reactor "shutdown":
Reactor #4 exploded in 1986;

Reactor #2 was shut down in 1991 following a fire that broke out in the adjacent turbine hall. While the reactor itself wasn't damaged, the then-current Ukrainian government decided to discontinue using it Link;

Reactor #1 was shut down in 1996, followed by reactor #3 in 2000 Link.

And if I understood this post correctly, they plan to start connecting the two halves of the arch on december 1st.

Love your updates, Beber! Thanks for staying on top of this!

So they're anticipating connecting both halves of the arch by December, assuming that translation was correct.
Does that seem like a realistic prediction, given that there's at least one more lift on the second arch? It gives them three months, so maybe that's enough time...

It seems very optimistic, almost impossible. I know the third lift was scheduled for this year, and that seems to be a more realistic goal. But I'm not sure whether the source is reliable or not, and I'm not even sure I got the translation right.

In other news, I discovered today that the live webcam also provides regular HD pictures, uploaded here every 4 minutes.

In 1991, Reactor No. 2 suffered a major fire, and was subsequently shutdown. In November 1996, Reactor No. 1 was shut down, followed by Reactor No. 3 in 2000.

(Reactor No. 4 is the one that exploded down)

If we're looking at speed of shutting down I believe the method used for reactor 4 is the quickest but unfortunately the messiest.

(Hopefully people have realised I'm being sarcastic!)

I'm impressed at the speed the New Safe Confinement is being erected, especially in an area which isn't the best place to be working. Will the structure just be for dismantling the reactor 4 building or will it go along and dismantle the rest of the plant?

Pretty sure the NSC will be used just to contain/dismantle reactor 4. Based on what I've seen, the NSC will be slid over reactor 4, but that'll be as far as it goes.

One of the main concerns surrounding reactor 4 is the amount of radioactive particles still inside the old containment structure that could get kicked up by a good breeze or storm. The other reactors don't have this issue, so I'm guessing that if/when they get around to dismantling the other blocks, they will use regular methods of dismantling & disposal.

Reactor 4 is, obviously, a very special case.

Looks like they got a Wumag Palfinger WT 1000. With a max height of 102.5m, it's going to be interesting to see it in action.

From the looks of it, they could start the final lift in less than two weeks.

Great update, Beber!

Correct me if I'm wrong, but are they doing the lifts to the second arch first before attaching the adjoining sections?

If so, I wonder why they changed it up from what they did on the first arch.

They only did the "attach before lift" twice. They had problems with the "slidding" supports that handles the lateral move of the extra sections.

Also, VIUR just confirmed my suspicions: final lift is scheduled for next weekend, and the two halves will in fact be joined at the end of november. Work will then be suspended for the winter (like every year).

Ah, ok. That makes much more sense now. Thanks!

So they are going to try and get the two halves joined before the end of the year, eh? Good to see a lot of progress being made!
