Today, on the 33rd anniversary of the Chernobyl disaster, we premiere a new video chronicling the history of the New Safe Confinement, the miracle of modern engineering which encases the nuclear power plant's damaged reactor. The New Safe Confinement (NSC or New Shelter) is a structure built to confine the remains of the number 4 reactor unit at the Chernobyl Nuclear Power Plant, in Ukraine, which was destroyed during the Chernobyl disaster in 1986. 1 The New Safe Confinement (NSC) was designed to prevent further radiation leaks from Ukraine's stricken Chernobyl nuclear power plant. It took two weeks in November 2016 to slide the massive steel NEW YORK — After many years of advocating to end solitary confinement, New York became the newest state to limit use of the practice. The passage of the Human Alternatives to Long-Term Solitary Confinement (HALT) bill, which Governor Cuomo signed into law on Wednesday, April 1st and will go into effect in 2022.

The New Safe Confinement (NSC) is a multipurpose complex for Shelter Object transformation into an environmentally safe system, consisting of 19 sub-structures, including the main one, which is an arch-shaped protective structure with a special double cladding, as well as specific foundations, West and East end walls, custom-made bridge cranes, a multipurpose ventilation system, a process complex with sites for decontamination, fragmentation and packing of radioactive materials, sanitary Chernobyl New Safe Confinement (NSC or New Shelter) is a structure built to contain the remains of the No. 4 reactor unit at the Chernobyl Nuclear Power Plant near Pripyat, Ukraine, destroyed during the Chernobyl disaster in 1986. The structure also encloses the temporary “sarcophagus” built around the reactor immediately after the disaster.

"Keep in mind, this is a one-of-a-kind structure, The New Safe Confinement will be sealed off from the environment hermetically. Finally, after intensive testing of all equipment and commissioning, handover of the New Safe Confinement to the Chernobyl Nuclear Power Plant administration is expected in November 2017.” PRIPYAT, UKRAINE - JULY 2: The 'New Safe Confinement' at the Chernobyl Nuclear Power Plant on July 2, 2019 in Pripyat, Ukraine. In November 2016, the 'New Safe Confinement' structure was shifted into place to prevent the decaying reactor from further contaminating the environment and eventually allow its dismantling; the Ukrainian government will soon be taking control of the new confinement 2020-02-07 The New Safe Confinement is a structure built to contain the remains of the No. 4 reactor unit at the Chernobyl Nuclear Power Plant near Pripyat, Ukraine, destroyed during the Chernobyl disaster in 1986.

But the SIP’s crowning glory – is, without a doubt, the construction of the New Safe Confinement (NSC) – an immense steel arch, designed to last for 100 years, that will protect the sarcophagus from the elements, and enable engineers to safely and methodically tidy up a nuclear legacy that has troubled the world for the past 27 years. 2016-12-05 The New Safe Confinement is a vital step in addressing the vital issues of containing and cleaning of the radioactivity. Additionally, the New Safe Confinement Structure is a very efficient way to contain the radiation; it is a fast solution, yet one that can last for centuries. While commissioning of some of the equipment and technological systems within the Chernobyl New Safe Confinement progresses, many of the systems are now in operation. Chernobyl’s giant New Safe Confinement (NSC) was moved over a distance of 327 metres from its assembly point to its final resting place, completely enclosing a previous makeshift shelter that was hastily assembled immediately after the 1986 accident. New Safe Confinement concept approved.

2021-04-09 · Chernobyl New Safe Confinement (NSC) The Chernobyl New Safe Confinement (NSC) is an arch-shaped structural shelter being built to confine the radioactive material at Chernobyl Unit Four, protect the existing temporary object shelter (sarcophagus) from weather damage, and enable the decommissioning of Unit Four.
