4. Reactor Entombment: In event of a full-on core meltdown, entombment of a cracked reactor is necessary, as was done in Chernobyl. An out-of-control reactor will have to be encased by tons of concrete mixed with a neutron absorber like titanium dioxide. The process is slow and difficult requiring helicopter drops and high-pressure concrete pumps.

I think Putz is the only one that has made a Concrete Pump for Reactor Entombment. I could be wrong.

One can only wonder how it will turn out

you are wrong Schwig built them also. Th Russian government told them not to to talk about or take pictures.Carol doe not play by the rules.

You have any proof of that?

you can see a schwing m52 in the picture

Looks like a scray job to me.. Any idea how many tons we talk about???  

 ''Tons of concrete''.... thats from 1 m3 and up over ;-)

Ok really, any pump 2  you can tell that is a schwing? As far as I know and what I have heard only Putz has a made a pump like that before. If Schwing had one dont you think they would of taken a picture or two of it at the factory?

They will need operators as well, I'm in!

the picture above is the one with the schwing m52 ,you can tell by the shape of the first section with the ram at the back of the boom, putz never had a boom that shape in them days

Ok here is the picture with all the pumps, which one is a schwing?

Don't get me wrong, I love Schwing but lets give credit where credit is due. Putzmeister knows what its doing when it comes to this type of work. I would love to give Scwhing, Cifa or any other company credit also if they did something or have something to show they did the work. I would love to see a Scwhing prepped for radiation protection.

What kind of pumps are in Japan? Whats the biggest pump in Japan? does anyone know?

If I was Putzmeister I would be calling Japan and asking if they want a pump prepped just in case.

I think he might be right Todd.. You see the pump on the right on your 2nd pic.. On the first section you see the hydr cylinders.. The main cylinder is mounted on top of the first section. So its the kind of boom that (when folded together on the truck) is laying on top of the cabin like with a 52m/55m/58m schwing...

I don't recal any putz that has the boom on top of the cabin.. But I'm only young... I could be mistaking.. I also didn't know there was semi trailer 52 meters in the past...

It also says in the article that they used pumps from 4 different manufacturers.. total 10 pumps 7 of those where putz.. So 3 where from 3 different brands.. Ods are 1 was a schwing... 

Is this enough proof??

that boom looks alot like a schwing m52 you can see the tray on the 3rd section where the placing hose lays when it is folded up

Any Pump... Thats CLEARLY a schwing 52m yes..

Ok, for sure there was a Schwing 52. I was wrong. I stand corrected.

haha.. But we all see putz did a great job there ;-) But how the hell did they deliver the crete?? I don't see a leaded lining on those mixer trucks.. Did they work on remote control to?? I don't think they were that advanced in those days??

it does say in putzmeister post history that pumps where used from local firms until putz delivered theres. that discussion went a bit of topic for a bit lol

I realy get a bad feeling in the stomage everytime I see pics of that tjernobil scene...

Alot of the guys who helped out with those pours, died from Radiation poisoning.

The radiation levels at the time only allowed 60 mins max exposure before your shift was over and you had to return to the safe zone.

Most of the volunteers were military personell and they were not aware of the risks of extreme radiation exposure.

There was a schwing there also on that site at the time. That was pumping through 3 of its four sections (i.e 4th section was not used).

One of the Putzmeister pumps I was told, had returned to operation in Greece after the incident and many cement mixer drivers were complaining about intense headaches and some nosebleeds. Eventually they were forced to decommissioned it, last I heard. 

so maybe there is some truth to the rumor I heard; what I heard was, that one of the pumps used a Tschernobyl was making its way back to Western Europe, and a Putz service tech recognized the pump, called the authorities, a hole was dug at the side of the road and the pump was burried, most likely in concrete, right there at the spot, has anybody else heard that? 

Two Schwings at Chernobyl

The Schwing-Stetter equipment at the Shelter construction in Chernobyl

10 December 2010

The Schwing-Stetter equipment was used at the intervention of the Chernobyl tragedy. The unique auto pumps were involved in work at the construction of Shelter above the destroyed reactor of Chernobyl Nuclear Power Plant. This special equipment allowed receiving the uninterrupted supply of concrete at the buildings high levels, which has significantly reduced the radiation dose for builders.  

At the concrete placement into the walls of Sarcophagus the Schwing-Stetter concrete pumps were used. They had 50 and 60 meters distribution arms. Pumps were equipped with the remote control panels and cameras.

At such work conditions the equipment has to be very reliable and qualitative. This fact proves once again that the Scwing-Stetter technique deservedly occupies a leading position at the concrete equipment market.
 

First, I think Vasa posted on this, and at one time there were at least 5 pumps set up on the reactor. I saw a picture in Nat. Geo. and you could make out 3 pumps set up on the second level . Schwing and Putz.

I don't want to start some shit but conveyors were the first at Chernobyl with a Creter Crane, post mounted swinger and line conveyors. but pumps did help some. a freind took this picture and was smuggled out. Photos like this were not supposed to leave the country which was still the communist soviet union at the time. maybe they need some Loop Belt's in Japan

Belts r cool

Even if they would pay me a 100.000 dollars a week I would not volunteer to go any where near these reactors.. That radioactive stuff is so sickening...

Dipstick, I would go under the right circumstances. The latest protective gear and enough money to take care of the family if I didnt come back. Or if I was asked to go to help, with nothing in it for me, I MIGHT JUST GET ALL Dr. Strangelove on it. Just sayin, one hell of a call to duty, huh.

do they really just start covering it up with concrete? I noticed theres nothing else in the pic.

The post started off saying that Putz is the only manufacturer that OFFERS this style boom pump kit...not that other manufacturers have been used.  Schwing may have been used but they don't necessarily offer a radiation resistant boom pump kit.

guys, NO ONE OFFERS ANY TYPE of a radiation resistant boom pump kit or any thing that comes close. People have lost their lives trying to help the better of the good. Some to most had no idea what they were sacraficing their lives. This was a bad BAD deal for everyone involved. From what I understand in Japan, they do have secondary containment, and should not need covering. Maybe we should all say a prayer for these people other then see what we can sell them, or who helped first in Russia, I with draw my "send a loop belt" plug. These people are in trouble!

I had breakfast with the VP of Putzmeister somewhere around 1995 I can't remember his name, all I remember was he was quite young and he spoke 5 languages.. I asked him what the easiest sale they ever made was and his answer was Chernobyl. He said four brand new pumps and when they were done they just pushed them into the pile. He described the lead shields on the front. When I asked about the operators he said calmly,they all died!

 There were over 100 pump operators working at Chernobyl. At first each operator was allowed to work 3 hours which was quickly & drastically reduced to 30min. due to so many of them having immediate health problems from radiation exposure. Other workers, mostly Russian military, were only allowed to be on site for only a few minutes each day. 

 A large part of the operation that's often over looked is what took place underground with line pumps that pumped thousands of yards of concrete through 2400+ feet of system...    

 One of the 52m putzmeisters was a trailor model that was perched on the 2nd teir without a tractor with the assend hanging over the edge (#4)...

@ Christie... So it actualy looks like the whole thing was just a 'joke'.. These pumps were not radioactive proof at all.. All the operators died any way.

 They were equipped with video cameras on the tip sec.& and to monitor the hopper. As for the lead lined cab, the only one I can see is in the picture at the top of this page, folded up & not pumping. The pumps on the job dont look like they have lead lined cabs. Neither do the ones sitting in the nearby equipment graveyard.

 Here's a couple that sit in the graveyard without any lead liners...

The lead profing and cameras at the time where innovative, but I doubt they were utilised to their full capacity. They were moreso features to make the operator 'feel' safe. In this case feelings didnt play any detrimental effect on a persons health until it was too late.

OMG that looks like my first 52.....

In the picture that smooth belt posted it looks as if that could be a lead lined cab. It is kind of blurry but it sure looks like it may be the one from the picture up top. But you are right, it doesn't look like there are any others. I bet the first pump had the lead lined cab until they realized that it didn't really do anything for the operator but mess up visibility they scratched the idea.

Great with a camera on the boom and the hopper.. And then the monitor is mounted in the cabin. Like that would help anything. They might just as well stand outside..

But they didn't have so much fancy camera and remote stuff in those days I guess. The only way they would impress me now is when they make the whole operation remote controled from 50 km distance. With cameras and remote controles on the truck, outriggers, boom, readymixers , the whole lot. Its possible.. Not that hard actualy. they make remote controled cars already now.

I actualy get a bit double feeling about the fact that putz is making 'comercial' about this stuff. Any amature can mount a camera on a boom with a monitor in the cabin.. And if its realy true that all the operators died I would just not talk about this horror scene anymore in stead of being so proud about it.. But thats just a feeling though..

I can't imagine why the VP of Putzmeister would tell me the operators died unless they did. Keep in mind how far the radiation sickness spread around the area. I remember reading about poisonous crops several hundred miles away.

I believe one will find, most,if not all were military personel.

Good documentary about Chernobyl: http://www.youtube.com/watch?v=bSRC1_OZPIg&feature=relate There are multiple parts to this. Pripyat before and after: http://www.youtube.com/watch?v=GpTpRVU7wJ4&feature=fvwrel Lets hope we don't see anything like this in Japan.

I know work is tuff.with 3 kid's that need their dad.think i would pass on that poor.

It was like the calm after the storm Thursday evening as local attorney Don Banner made a last — somewhat chastened — appeal to the Pueblo County commissioners to approve a zoning request for a 24,000-acre energy park that would include a nuclear power plant.

and away we go,it would bring some much needed work to the industry

Many, as long as we have this bafoon for a president, you guys in Colorado or anywhere else in this country, you will never have to worry about nuclear power.  Some of his biggest money supporters are enviromental jackasses who will not allow us to drill for oil, natural gas or build nuke plants.  He even stated on record that he would bankrupt the coal industry.  Change we can all believe in.

its been announced, they are bringing in pumps..... how much an hour? off site cleanup?

Sany group sent them a 62m pump for free.

I not sure about all the companies but I heard most of the pumps were donated.
