… The sarcophagus was constructed under extremely dangerous conditions, with very high levels of radiation, and severe time constraints. construction of a New Safe Confinement (NSC). Workers in Ukraine will soon begin the task of moving a 31,000-ton steel cover over the radioactive ruins of the Chernobyl nuclear plant. The construction lasted for 206 days, from June to late November of the same year. This “new safe confinement” will not only safely contain the radioactivity from Reactor 4, but also enable the sarcophagus and the reactor building within to be safely taken apart. This paper describes the purpose and the design of the New Safe Confinement (NSC), which was raised and slid over the destroyed Reactor Unit 4 and 'Object Shelter' (SO) of the Chernobyl nuclear power plant and shows the examples of CFD modeling of these objects. The New Safe Confinement (NSC or New Shelter) is the structure intended to contain the nuclear reactor at Chernobyl, Ukraine part of which was destroyed by the Chernobyl disaster in 1986. Design of the sarcophagus started on May 20 1986, a little over three weeks on from the disaster. The NSC will be constructed adjacent to the OS to minimise radiation doses to construction workers, then slid over the OS on a runway system using hydraulic power. The giant structure constructed around the Chernobyl nuclear power plant to contain the radioactive material released in 1986 in one of history's worst nuclear disasters is crumbling. Webcam Prypjat: Kernkraftwerk Tschernobyl - Ein Blick auf den Baufortschritt des New Safe Confinement (NSC).

The NSC is an enormous arch-shaped steel structure which will protect the OS from the elements, confine any radioactive dust releases, and support a massive and unique crane system. The idea is to prevent the reactor complex from leaking radioactive material into the environment.
