Iznad oštećenog reaktora u Černobilu 29. novembra je
postavljena nova kupola koja treba da zaštiti postrojenje od spoljnih uticaja i
spreči širenje radijacije u narednih 100 godina. Izgradnja kupole je koštala
dve milijarde evra, a rezultat je napora međunarodne zajednice koja je želela
da otkloni opasnost od urušavanja starog zaštitnog omotača i obezbedi to
područje.
"Mnogi su sumnjali, mnogi nisu verovali. Čestitam
vam prijatelji! Da! Uradili smo to!", rekao je ukrajinski predsednik Petro
Porošenko na ceremoniji postavljanja kupole.
"Obeležili smo danas u Černobilu završetak radova na
postavljanju konstrukcije", ključne etape međunarodnog programa koji
Černobil treba da učini sigurnim, saopštile su francuske kompanije Vensi i Bujg
koje su realizovale projekat vredan dve milijarde evra.
Kompanija Novarka koja je učestvovala u projektu
saopštila je da bi kupola mogla da prekrije Stadion Francuske u Parizu ili
njujorški Kip slobode.
Metalna konstrukcija lučnog oblika teška je 25.000 tona,
a sa dodatnom opremom imaće 36.000 tona. Kupola je visoka 108 metara, prečnika
162 metra a njen vek bi trebalo da bude najmanje 100 godina.
Nova kupola biće u upotrebi od kraja 2017. godine, nakon
postavljanja neophodne opreme koja će se koristiti za rušenje starog betonskog
omotača iz sovjetskog doba koji je postavljen oko reaktora broj 4 posle
havarije.
Prvi zaštitni oklop oko centrale u Černobilu izgrađen je
od 400.000 kubnih metara armiranog betona. Na postavljanju tog omotača radilo
je 90.000 ljudi u teškim uslovima.
Njegov vek je trebalo da bude između 20 i 30 godina, ali
su prvi radovi na njegovom pojačanju počeli još 1999. godine, a nastavljeni
tokom 2000-tih.
Međunarodna zajednica je zatim, suočena sa opasnošću da
se stari omotač uruši, odlučila da finansira izgradnju novog omotača. U tom
cilju Evropska banka za obnovu i razvoj je formirala fond a radovi su počeli
2012.
Kupola bi trebla da bude otporna na zemljotres jačine 6
stepeni Merkalijeve skale.
Reaktor u Černobilu je ekspoldirao 26. aprila 1986. u
1.23 prilikom bezbednosne provere. U sledećih 10 dana postrojenje je gorelo
emitujući u atmosferu radioaktivne materije koji su, prema nekim procenama,
zahvatile tri četvrtine Evrope, a posebno Rusiju, Ukrajinu i Belorusiju, tada u
sastavu bivšeg SSSR-a.
Tokom četiri godine oko 600.000 građana Sovejtskog Saveza
radilo je na mestu nesreće na gašenju požara, postavljanju betonske zaštite,
izolaciji oštećenog reaktora i čišćenju okoline.
Danas se i dalje vodi debata o broju žrtvava katastrofe i
njenim posledicama po ljude i prirodu. Prema zvaničnim podacima, neposredno je
stardalo oko 30 ljudi, ali neke procene govore o mnogo većem broju ljudi.

Over the
damaged reactor at Chernobyl on 29 November set a new dome that should protect
the plant from external influences and prevent the spread of radiation in the
next 100 years. Construction of the dome has cost two billion euros, a result
of the efforts of the international community that it wanted to eliminate the
risk of collapse of the old protective sheath and secure the area.
"Many
doubted, many did not believe it. I congratulate you friends! Yes! We did
it!" Said the President of Ukraine Petro Poroshenko at a ceremony
installing the dome.
"We
celebrated today at Chernobyl completion of the construction, setting up"
key stages of international programs that Chernobyl should make safe, officials
said the French company Vensi and Bujg which have implemented a project worth
two billion euros.
Novarka
companies that participated in the project said it would be unable to cover the
dome stadium of France in Paris or New York's Statue of Liberty.
Arc-shaped
metal structure weighs 25,000 tons and with additional equipment will be 36,000
tons. The dome is 108 meters high with a diameter of 162 meters and the battery
life should be at least 100 years.
The new dome
will be in use by the end of 2017, after setting up the necessary equipment to
be used for the demolition of the old concrete layer from the Soviet era, which
is set around the reactor number 4 after failure.
The first protective
shield around the plant in Chernobyl was built from 400,000 cubic meters of
reinforced concrete. On the setting up of this layer there were 90,000 people
in difficult circumstances.
His eyelids
had to be between 20 and 30 years, but the first works on its intensification
began in 1999 and continued during the 2000s.
The
international community is now faced with the danger that the old layer
collapses, decided to fund the construction of a new tread. To this end, the
European Bank for Reconstruction and Development has established a fund
construction started in 2012th.
The dome would
I need to resist an earthquake measuring 6 degrees Mercalli scale.
The reactor at
Chernobyl ekspoldirao April 26, 1986 at 1:23 at security checks. In the next 10
days the plant is burned, emitting into the atmosphere of radioactive materials
that are, according to some estimates, affected three-quarters of Europe,
especially Russia, Ukraine and Belarus, then part of the former USSR.
During the
four years about 600,000 people Sovejtskog Alliance worked at the scene to
extinguish the fire, setting concrete protection, insulation damaged reactor
and cleaning the environment.
Today it is
still a debate about the number of victims of the disaster and its consequences
for people and nature. According to official data, directly STARDALE about 30
people, but some estimates put the much larger number of people.
