В эти дни в Казани проходит всероссийский сход предпринимателей татарских сел регионов РФ и РТ, а мы знакомим вас с одним из таких бизнесменов. Житель Мамадышского района Малик Назипов, 25 лет занимавшийся изготовлением мебели, 5 лет назад решил начать новое дело: купил два заброшенных сарая, две овцы и старую технику. Сегодня в его хозяйстве около 100 голов: овцы, бараны и ягнята. Как создать крестьянско-фермерское хозяйство с нуля, какая помощь нужна фермерам от государства и почему многие бросают этот бизнес, так и не дождавшись первых результатов — об этом в репортаже «БИЗНЕС Online».
Ceremony marks key milestone in international project to transform site of 1986 accident
A ceremony in Chernobyl today marked the successful conclusion of the sliding operation, a key milestone before the fi nalisation of the international programme to transform Chernobyl into an environmentally safe and secure state by November 2017.
Thirty years after the nuclear disaster in Chernobyl, the radioactive remains of the power plant’s destroyed reactor 4 have been safely enclosed following one of the world’s most ambitious engineering projects.
Chernobyl’s giant New Safe Confi nement (NSC) was moved over a distance of 327 metres from its assembly point to its fi nal resting place, completely enclosing a previous makeshift shelter that was hastily assembled immediately after the 1986 accident.
The structure was built by Novarka, a consortium of the French construction firms VINCI Construction and Bouygues Construction. Works started in 2010.
We visit the Unit 2 reactor hall (central hall) at Chernobyl Nuclear Power Plant in November of 2016. My video editing skills are minimal and I am slow, so for better material please visit the channel of my nuclear companion Bionerd23:
The RBMK is notable for its circular reactor lid where the control rod drive mechanisms reside and where loading and unloading of fuel occurs by means of a massive crane-mounted machine. In essence, the hall is a heavy-walled hot cell designed to shield potentially high radiation levels while fuel operations are underway. The hall also contains the short-term spent fuel storage basins, fresh fuel storage, a fuel transfer hatch to ground level, and access panels into the upper steamwater communication lines linking the reactor channels to the steam separators on either side. Unit 2 at Chernobyl has been shut down since a fire in 1991 damaged its generators and feedwater system. The reactor is defueled and dry, as are its spent fuel basins.
Some highlights of this video tour:
0:31 The reactor building elevator threatens to malfunction and we take the stairs instead.
3:03 Entrance to the anteroom of the Central Hall on the + level, where we put on additional PPE clothing.
5:02 Central Hall shielding maze
7:20 Gamma radiation above pressure tubes on reactor face is about 3.3 mR/h.
10:10 Fuel element stringers in the spent fuel pool are locally contaminated and spicy, with one measurement showing 2 R/h.
14:16 Discussion of the division of reactor channels between fuel and the protection and control (SUZ) system, noting that one SUZ channel has been repurposed for neutron transmutation of silicon. The RBMK was particularly good for this, and it occurred in Units 2 and 3 at Chernobyl.
14:58 Ascend the scaffolding to the refueling machine operator's compartment and look out the leaded glass window.
what is the purpose of the Novarka project? when will the new sarcophagus be completed? what happens afterwards? and why did they remove the chimney and built a new one?

While the detritus of the early years of our atomic age may pose a major challenge, there's a far more urgent issue facing the authorities in Ukraine - repairing the dome covering Chernobyl's nuclear reactor.
