New Safe Confinment

In 1986, after the nuclear explosion of the unit 4 reactor at Chernobyl Nuclear Power Plant the Government of former USSR made a decision to bury the remains of reactor in concrete and steel temporary "sarcophagus" . It was built in a very short time of 6 months in order to quickly reduce on-site radiation levels and let 1-3 reactors continue its safe work. But hasty arrangement of the “sarcophagus” led to errors in construction and moisture-induced corrosion over the last 30 years has degraded the construction futher . All of this made the temporary shelter dangerously unstable. For the last 10 years there existed a potential hazard of the shelter to collapse and release of radioactive dust into the environment. That’s how the idea of development of an enormous structure called the New Safe Confinement appeared.


First of all, Ukraine's government provided an international competition in 1992. Main groups of contestants suggested that the structure should be in a form of arch and it should be built near the reactor and then slid over the existing old shelter. It was the best decision as such construction plan reduced possible dangerous radiation doses for workers. And only in September 2007 the Vinci Construction Grands Projets and Bouygues Travaux Publics won the competition. According to contract they were going to build a confinement with the French consortium Novarka. The full amount of €2.1 billion needed for building was obtained thanks to contributions from more than 40 countries and to the European Commission and the European Bank for Reconstruction and Development. On top of that it is known that more than 10,000 different people made contributions to building for the structure project.


Last year, 29th of November, 2016 was the day when the world’s largest moving land structure finally covered the Chernobyl Nuclear Power Plant doomed fourth reactor.


The international mega project is huge and fascinating. This steel tomb stands 354 feet tall , 843 feet wide 531 feet long and has weight of 36,000 tonne Real example of what can be achieved if people from all over the world are working together. This New Safe Confinement is expected to entomb the site for next 100 years. Its construction will safe old shelter from snow and rain influence, and will keep environment safe in case of radioactive dust release. Also NSC was designed to be equipped to remotely dismantle unstable structures and get fuel-containing materials from the "sarcofagus".
