chernobyl new safe confinement

Water is leaking through the sarcophagus via holes in its roof, becomes radioactively contaminated, then seeps through the floor of the reactor into the soil below. The First Confinement Actions. The contract for this unprecedented design and construction project was awarded to the Novarka consortium led by the French construction companies Bouygues and Vinci in 2007. Construction of the arches completed. Tubes protruding from the lid are the so-called fuel assemblies, and the cone-shaped elements from above are sensor-monitors for monitoring radiation levels. Later, the building was given the unofficial name of Sarcophagus. Today, experts are confident that the sarcophagus, with due care, will last for more than a decade. During the trial operation, almost all NSC equipment and systems was operated in design mode within 72 hours. Also dumped inside the sarcophagus are thousand of cubic metres of nuclear waste created by fragments of the destroyed reactor building and contaminated soil that has also been dumped into the sarcophagus. After the accident under the Shelter, about 80% of the fuel mass remains, which have a high radioactive background. Its frame is a huge lattice construction of tubular steel members, supported by two longitudinal concrete beams. Never before has such a huge structure been constructed at a heavily contaminated site. Some project milestones, including infrastructure and preparatory work such as the NSC pilings, were completed. Our team of engineers devised a prototype arch to confine, sort, store, and stockpile radioactive waste materials – while ensuring maximum protection for workers on site. 08 February 2019.

Immediately after the creation of the first shelter over the destroyed reactor, it was clear that the Sarcophagus was not a reliable defense. The structure was moved into position in November 2016. LIFE BEFORE THE CATASTROPHE PART 2. They were mostly volunteer specialists who examined all the sub-reactor facilities, studied where all the radioactive substances from the reactor shaft had gone and in general they tried to understand what actually happened at the Chernobyl nuclear power plant. The New Safe Confinement was a structure built with the purpose of covering the destroyed Reactor 4 and the old sarcophagus structure. It’s very dangerous and difficult to work here. This is very much. Coal miners were drafted in to dig this tunnel under the reactor and by 24 June four hundred coal miners had built the 168m long tunnel under the reactor.
