Because it's difficult to avoid the high radiation levels within the old sarcophagus, and it was pretty shoddily built to begin with.
Most of the old sarcophagus is supported by the walls of the ruined reactor facility, which was damaged in the accident itself. The new one will be self supporting, and much larger, and thicker.
They tried already to repair it in '98, but it obviously didn't work, since it's still rotting away.

ChNPP released two videos of the lift, including one timelapse.

Also, the old sarcophagus was designed to be built as fast as possible - its low endurance is a price for this. Its estimated lifetime was 25 years, as the designers in 1986 were convinced that the Soviet Union would find ways and resources for dealing with the disaster results. Of course independent Ukraine had neither.
It's also worth mentioning that the NSC will support overhead cranes and heavy machinery needed for dismantling both the old sarcophagus and the reactor building itself.

Not a lot of activity since the first lift. I guess the snow isn't helping.

Update from ChNPP. Work recently restarted, after being stopped due to the holidays and weather conditions (I guess). They also had a minor electricity delivery problem, which is all solved by now.

They are currently dismantling the (temporary) lifting towers, and working on the arches (slowly due to weather conditions).

Work is still going on slowly (winter and snow aren't helping).

However, I just wanted to share an information revealed by ChNPP, that part of the wall slab of the turbine room just collapsed. It is not a critical structure of the current shelter (even though it's adjacent to it), and there are "no changes in radiation situation".

It shouldn't impact on the construction of the NSC, but it shows that the new shelter is indeed needed.

Edit: Work stopped on the NSC until further inspection of the damaged area. A 2 week investigation was started today.

Well, according to the current Die Hard movie we could easily spray the reactor with some neutralizing gas and get rid of the radioactivity in minutes. Just do it!

Only the firemen died in the fire because they hadn't the necessary equipment to extinguish the fire in the turbine hall, near the reactors.
A number of plant workers died from the radiation as well. This is well documented. You can argue all you want about how many liquidators actually died vs. how many have crippling health problems for the rest of their lives.

There's also at least one plant worker who was killed during the initial explosion and is somewhere in the debris.

As has been said, the current sarcophagus has already outlived its design lifespan. The engineers that built the thing don't even think it is stable anymore. It's a rusting, decaying hulk that is full of holes that allow wildlife, wind, and moisture to enter. Plus the whole sarcophagus rests on a damaged wall of the original building.

Looks like others beat me to answering your inane comments, but if the recent collapse of a portion of the original building isn't enough for you to think that this project is warranted, I do not know what is.

Indeed the sarcophagus was built on the decaying reactor building and was built very hastily to prevent anymore radiation escaping

Did the liquidators actually have to pick up bits of the plant that had been blown up (like reactor walls, cooling rods etc) or did they have tools? And also why couldn't they have used an unmanned remote control device?

They used robots but the electronics were fried by the radiation. One even fell inside the hole when it went haywire.

As for the liquidators, they did both. I'm talking picking them up with gloved hands and shoveling them with cruddy little shovels.

This is a good documentary for footage, although the actual story re: casualties is still up for debate. I tend to think that the official figure is lowballed, but whatever I don't want to get into a huge debate.

Omg that documentary was so good but kinda freaked me out how something that major could have happened but the highest levels of Soviet Authority didn't know.

The poor men :'(

Just having a look on Wikipedia and it says a roof has collapsed:-

Quote:
2013 Collapse
On February 12th 2013, a 6,500 square foot portion of the roof and wall adjacent to the covered part of the turbine hall collapsed into the entombed area of the turbine hall. The collapse did not affect any other part of the Object Shelter or the New Safe Confinement. No variances in radiation levels as a result of the incident were detected.[9] The roof which collapsed, was built after the Chernobyl disaster.

Work on the NSC restarted today.

And just FYI, the jacks used to lift the arch are the ones that got the Kursk out of the bottom of the Barents sea.
