35 years later, an unexpected problem occurred at the Chernobyl Nuclear Power Plant, which exploded as a result of an accident in 1986 and killed thousands of people. Experts do not yet know how to deal with this.
When the Chernobyl Nuclear Power Plant in Ukraine caught fire 35 years ago, it caused the world’s worst nuclear accident and the fallout spread to Northern Ireland, Britain and the Black Sea.
Desperate Soviet officials covered the dilapidated reactor with a thick concrete “sarcophagus” to prevent further radioactive contamination from spreading from the wreck of the plant’s No. 4 reactor.
NUCLEAR REACTIONS AGAINST
In 2010, a second shield was built around the reactor to prevent fatal leakage.
According to the information in Milliyet, it now seems that nuclear reactions started spontaneously inside the protection shield.
‘LIKE ROOTS IN BARGAIN’
Nuclear materials chemist Neil Hyatt of the University of Sheffield says the fire started again “like embers in a brazier”.
Deep inside the reactor, a closed chamber reveals a small but constantly increasing neutron flux, an indication that nuclear fission is taking place in the reactor.
One of the most important problems for scientists trying to control radioactive pollution is rainwater.
During severe storms, water enters the shield, causing deadly radioactivity to leach into groundwater.
In June 1990, a scientist jumped into the reactor chamber and endangered his life by spraying the radiation-absorbing gadolinium nitrate solution into the potentially critical part of the reactor.
NO CLEAR PLAN
But beyond these firefighting efforts, the Ukrainian authorities have no clear plans for how to prevent a new meltdown.
There is a long-standing plan to remove the reactor’s fuel cells, FCMs, and store them underground.
The European Bank for Reconstruction and Development has offered to fund this complex and dangerous procedure, but the operation remains on hold as the “embers” of the fire continue to heat.
Maxim Saveliev, of Ukraine’s Institute of Nuclear Power Plants Security Issues, told Science magazine that it would be dangerous to try to dismantle the sealed reactor to ascertain exactly what happened.
‘WE CANNOT IGNORE THE POSSIBILITY OF ACCIDENT’
Saveliev said, “There are many uncertainties, but [bir] We cannot ignore the possibility of an accident, “he said.
Worst of all, scientists are still not entirely sure why the nuclear reaction is starting again.
“It is not yet clear what the mechanism might be,” says chemist Hyatt.
