Thank you, I am surprised how low the values are.

 

[African Rover]

How badly do you think of Ukraine? I mean, it is not Western Europe, yes, but it isn't a rathole like North Korea either!

Do you really think the reactors would be operated if operating personnel would "show radiation caused health effects"?

I am sorry I never meant to insult the Ukraine or question the intelligence of the nuclear engineers that worked and still work there. I just asked because of all that drama surrounding Fukushima and the exaggerated fear of radiation. I see a.ua. actually sent a link that let's you see the site and shows today's radiation readings. I am surprised to see how low they are.

 

[nikkkom]

Thank you, I am surprised how low the values are.

That picture does not show any readings on top or inside Unit 4. You can see that two largest readings on the pic are those two closest to it.

IIRC on the Sarcophagus roof gamma field today is around 10 mSv. (That would be 10000 uSv if it would be shown on that picture).

Thank you, I am surprised how low the values are.

This is not surprising.
The whole area has been subjected to nuclear decontamination.
Very specific.

Since October 1986, in connection with the planned completion of the construction of the "Shelter" and the start of 1.2 units launched massive work on bringing territory of the Chernobyl NPP in reasonable the form
Here's an excerpt from one of the documents.

Government Commission in the aftermath of the accident.

"In order to reduce the power of gamma radiation in the Chernobyl nuclear power plant ... to develop and implement additional measures to decontaminate areas block number 3 and number 4, and the area adjacent to the plant (including construction base and warehouses)...
Task force of the USSR Ministry of Railways to provide a daily supply of the Southwest and the Lviv railway flatcars at 10 st.Kamenets-Podolsky, and Rock-Podolsky to deliver concrete mix to st.Tolsty Forest ..
Task force of the USSR Ministry of Defense to allocate 100 personnel to perform work on the laying of asphalt mix in the Chernobyl nuclear power plant , 20 vehicles for the transport of the mixture , as well as provide unloading platforms with a mixture of at st.Tolsty Forest and loading it in the vehicle ...
Minavtotransu USSR on October 15 this year allocate 50 vehicles for the delivery of the Chernobyl hot mix ...
USSR State Supply in the bill to allocate funds USSR Ministry of the USSR Mindorstroyu 5000 tons of bitumen to perform the work of asphalting the Chernobyl nuclear power plant. Goskomnefteproduktom USSR put 5 tons of bitumen Mindorstroyu USSR on its application ... "

deactivation is obviously not able to fully eliminate radiation contamination and has been implemented on top of filling materials clean contaminated soil followed by asphalting the surface. As a result , in the district of "Shelter " and block 3 entrances to the building and the railroad tracks were below the level of coverage in

October 31, 2013 the first block of Ventilation Stack (VS-2) of ChNPP 2 generation has been dismantled. Weight of the dismantled block is 33 tons. The block is located at specially prepared site where it will be fragmented to move it in Unit 3 Turbine Hall for temporary storage.
Radiation situation parameters were monitored continuously during the work. Controllable parameters of the radiation situation do not exceed the design control levels. Additional radiation survey of dismantled block and its preparation for fragmentation is underway.
Dismantling of VS-2 will be performed by sequentially removing of separate blocks using the high capacity crane DEMAG. In total 7 blocks will be dismantled with weight 330 tons.
Planned completion date for VS-2 dismantling is December 10, 2013.

Gratifying that this clean up is making headway.
Still a huge headache, but at least somewhat circumscribed.
Just wonder whether it will take a quarter century to get as far at Fukushima as well.

I am delighted that radiation was monitored.
However, are we mere mortals not deserving to know the measured levels?

the less you know - better sleep

the actual levels of accumulated dose can be seen working on personal dosimeters.
The level of exposure rate, as you know, depends on how far away from the source.
The sources on the tube a lot and they are not uniformly distributed.
As far as I know, the maximum dose of 1 mSv.
far more dangerous specific activity of the alpha-emitters in the air.
It is not reported ...

However, the installation of the shelter continues during disassembly of the pipe, then everything is OK.
Those who work on the pipe and next to her wearing a mask, it is visible in the photo.
In addition tools were used for fixing dust.

VS-2 dismantling was completed.

Works on dismantling of the ChNPP II Generation Ventilation Stack (VS-2) were completed. 7 blocks with total weight of 330 tons were dismantled according to the Work Execution Plan.
Works on fragmentation of the dismantled blocks are underway within the specially prepared areas. The dismantled fragments are transported to Power Unit No.3 Turbine Hall by special vehicles for temporary storage.
440 fragments have been already placed at the Turbine Hall.
Prior to the placement, the fragments are subject to dust fixation by special compound, and pass the acceptance control for compliance with the criteria of temporary placement at the reserved areas.

Works on recovery of Unit 4 Turbine Hall roof are in progress within the Shelter Object Local Zone

Crane­ КС–8165 with lifting capacity 100 tons was delivered to the Chernobyl NPP industrial site. It will be engaged into works on recovering the confinement of Unit 4 Turbine Hall.
This crane, along with the other two being already on the site, will be used to remove the remaining wall panels damaged as a result of the collapse in February this year. These works are of high complexity, because a direct access to the panels is blocked by metal towers erected during elimination of the accident consequences in 1986. Following the removal of the damaged panels from behind the metal towers and their bringing down on the ground, they will be fragmented and transported out for disposal at the RWDF “Buryakovka”.
In addition Crane­ КС–8165 will be used for installation of a covering three-dimensional block, by which the opening in the roof of Unit 4 Turbine Hall at axes 50-52 will be closed. Another crane, the forth one, lifting Crane POTAIN MD-3200 will assembled on the site to lift and install the covering three-dimensional block. All metal structures of the covering three-dimensional block have been already delivered to 10-km zone, and part of them has been already delivered to the ChNPP industrial site for pre-assembly

Consequences airstrike on Chernobyl

...Another 6 (six !) years ago by the Russian military invasion plan was developed in Ukraine. In the invasion plan envisaged, in order to intimidate and demoralize the population of Ukraine, apply air demonstration nuclear explosion over the territory Polesie. Quote from the article I.Dzhadana "Operation" Clockwork Orange '"(2008):" Air Demonstration nuclear strike in the stratosphere in the southern part of the Pripyat marshes produced at night, would help immensely in this case. He would not inflict significant damage, except for disabling power lines and electrical appliances in a radius of 100 km. But he would have been seen in hating "Muscovites" Lviv and even in Poland. He immediately sobered be hotheads, clearly indicating answered by a serious commitment to the Kremlin. "

For skeptics who believe that this revision chornobyl.in.ua exalted Bandera eating breakfast Russian children and the elderly, we note that in the article "Operation Clockwork Orange" (again, written by Russian military analyst!) Described three stages of intervention in Ukraine. Surprisingly, the first phase of the war with Ukraine, described in the article has already been implemented. Seizure of the Crimea occurred in full compliance with the script operations "Clockwork Orange." Similarities are impressive - the author with an accuracy not only have the number of Russian invaders, the script of their movement in the Crimea, but even just have numbers of military units of the Russian Federation armed forces involved in the conflict. And this, in April 2008! In this regard, there is currently no reason to distrust the Russian analyst (more about the stages of Russian intervention on the territory of Ukrainehttp://www.russ.ru/pole/Operaciya-Mehanicheskij-apel-sin

The most interesting thing about Chernobyl works today are money flows: how much and whose money is spent (Europe's? Ukraine's?) and who benefits - who owns the companies which execute vast number of projects.

There are many influental people interested in prolonging Chernobyl works ad infinitum.

One of useful approaches is to avoid actually closing for good any open problem - it's best to partially solve it instead.

In the Chernobyl zone built storage of spent nuclear fuel


"Cabinet has decided that will take another step toward energy independence. It is about building the Central repository for spent nuclear fuel. Today addressed the issue of allocation of land in the Chernobyl zone with a total area of ​​45 hectares, "- said Nedashkovsky...

..."The construction of the repository will be engaged in a U.S. company Holtec International. The tender was held in 2004, and in late 2005 a contract was signed with the company. It will build turnkey this store - said Nedashkovsky. - The company will build up to the moment of delivery of the starting complex, and then to the extent of technology transfer will be carried out Ukrainian construction company. Store will operate "Energoatom". Cost of the project on the feasibility study for the entire fuel filling stage - UAH 3.7 billion, the cost of launching complex - 1.2 billion UAH ", - explained Nedashkovsky.

He also clarified that the facility will be used to fuel Rivne, Khmelnytsky and South-Ukrainian NPP...
.
...Design and construction of a centralized repository conducted in compliance with the Civil Protection, technological, nuclear and radiation safety, international treaties.

The total storage capacity of 16,529 spent fuel assemblies of VVER-440 and VVER-1000.

The contract for construction CSSNF between "Energoatom" and winner of the relevant tender company Holtec Internatinal (USA) was signed in late 2004, but for many reasons, including because of the change of the political situation and the economic crisis in 2008, the project was actually frozen .

The Cabinet of Ministers of Ukraine in the current year on direct activities on decommissioning Chernobyl and transformation of the "Shelter" into an ecologically safe system 745 271 000 UAH.

This is stated in the government decree number 108 of April 16, 2014.

According to the document, to maintain in a safe condition of the first, second, third Chernobyl NPP and existing spent fuel storage will be allocated Rs 376.508 million for decommissioning and partial dismantling of individual systems and components units - UAH 63.617 million.

To carry out organizational and technical measures for the management, operation, maintenance, repair systems, life support Chernobyl ensure monitoring of the Nuclear and Radiation Safety Cabinet send UAH 234.182 million.

The creation of the industrial area of ​​Chernobyl infrastructure for the management of spent nuclear fuel and radioactive waste in 2014 provided 27,264,000 USD, and for the release of nuclear fuel units - 43.7 million UAH.

As UNIAN reported earlier, the Cabinet of Ministers of Ukraine in 2013 sent for events on decommissioning Chernobyl and the transformation of the "Shelter" into an ecologically safe system of 728.271 million UAH.

Completion of construction of the "Shelter" at Unit 4 of the Chernobyl nuclear power plant is scheduled for 2015. The cost of construction is estimated at 980 million euros, while contracts with concern "Novarka" fixed sum of 935 million euros.

With country being very much strapped for cash, and with increased freedom of press and grassroots activity against corruption, I found this, much-needed journalist investigation of corruption in govt agencies tasked with dealing with Chernobyl.

It's not a particularly deep investigation, but a few interesting tidbits there.

First, wood from the zone is being harvested and sold (there are videos of trucks hauling logs). Apparently, officials who can approve such activity sell it very cheaply (much below market prices) to their shell companies.

Second, the old guy (Volodymyr Tokarevsky) in the video mentions that The Arc is being financed and "in process of being constructed" for something like 12 years, cost has ballooned from $500m to $2bn - and continues to increase.

He also mentions that almost every project ever started there (spent fuel storage, liquid waste treatment plant) is never finished.

Cynically, all is just as I suspected it to be.

Information on radiation state of aerial environment at Chernobyl NPP site Created on 29 April 2015
At Chernobyl NPP industrial site routine monitoring of volumetric activity of 137Cs (Cesium-137) in air samples is constantly performed by the stationary control station. The volumetric activity of 137Cs in the sample of ambient air is within the range not exceeding the maximum values for 2014 and the 1st quarter of 2015.

Since April 27, 2015, the personnel of the radiation monitoring laboratory in ChNPP RSS started a sampling using the portable sampling equipment additionally to the scheduled radiation monitoring. The results of the express measurements show, that the volumetric activity in air samples is at the level of minimum-measured activity. Exceedance of the control levels is not fixed. Confirming the results obtained on the basis of the data of stationary radiation monitoring system - component of the Integrated Automated Monitoring System (IAMS). This system allows monitoring of nuclear and radiation safety of the Shelter object and the surrounding areas, including the state of the main building structures and seismic activity, in real-time.
