Watch Chernobyl safe confinement - sav75841 on Dailymotion. Each of the steel tubes is made of high-strength steel to reduce cost and assembly weight. The New Safe Confinement accounts for €1.5 billion. [8][1], The original shelter, formally referred to as the Shelter Structure and often called the sarcophagus, was constructed between May and November 1986. The purpose of the new Chernobyl new safe confinement. An arch would be easier to slide than a square box. A new shield covers the Chernobyl reactor. The study selected the sliding arch concept as the best solution for their further investigations and recommendations, primarily to reduce the chance of the construction workers receiving a harmful dose of radiation. Assembly of first and second arches to form Bay 1, installation of east wall on arch 1.

Sliding of the structure along foundation rails was a difficult process. A new safe confinement at the Chernobyl nuclear power plant is planned to be put into operation in December 2018. [43], Containment structure for the nuclear reactor at Chernobyl, Ukraine, Parts of this article (those related to the specification description ) need to be, The New Safe Confinement at Chernobyl Nuclear Power Plant in its final position over the damaged reactor 4 in October 2017. swf.flashVar("logoHidden","N"); [4], The word confinement is used rather than the traditional containment to emphasize the difference between the containment of radioactive gases—the primary focus of most reactor containment buildings—and the confinement of solid radioactive waste, which is the primary purpose of the New Safe Confinement. These cranes travel east to west on common runways and each has a span of 84 metres (276 ft). The shelter was constructed under extreme conditions, with very high levels of radiation, and under extreme time constraints. Their dosimeter beeps if the limit is reached and the worker's site access is cancelled. Report. New safe confinement of Chernobyl Nuclear Power Plant, Prypyat. It consists of various materials including nuclear material, stone, sand, loamy sands, unreinforced concrete, and construction wastes. [1], The New Safe Confinement is a megaproject that is part of the Shelter Implementation Plan and supported by the Chernobyl Shelter Fund. The NSC construction area is the arch on the left-hand side, The NSC nearing completion in October 2016, NSC placed over reactor four of Chernobyl nuclear power plant as of September 2017, with the monument to the constructors of the sarcophagus in the foreground, The European Bank for Reconstruction and Development (EBRD) is responsible for managing the Shelter Implementation Plan, including overseeing the construction of the New Safe Confinement. The New Safe Confinement is designed to prevent the release of radioactive contaminants, protect the reactor from external influence, facilitate the disassembly and decommissioning of the reactor, and prevent water intrusion. //swf.flashVar("colorPanel","#FF0000"); [26], Workers have a daily and annual radiation exposure limit. Several options were considered for the foundation design for the New Safe Confinement. These external panels are also used on the end walls of the structure. Although it concedes Paris and the Eiffel Tower in height, but the metal used for the construction of facilities at Chernobyl, could build three such towers. As of 2018[update], no policy has been decided for the disposal and processing of fuel containing materials. The overall length of the structure is 150 metres (492.1 ft), consisting of 13 arches assembled 12.5 metres (41 ft) apart to form 12 bays. Deconstruction of the fragmentation, decontamination, and auxiliary buildings. The New Safe Confinement (NSC), a multinational project to construct a modern radiation sarcophagus over the destroyed reactor 4 of the Chernobyl nuclear plant in Ukraine, has been effectively completed, the European Bank for Reconstruction and Development (EBRD) said on … This is the biggest arched construction in the world, which will cover the outdated and disintegrating Sarcophagus of Chornobyl Nuclear Power Plant. swf.flashVar("hiddenPanel","5"); Mitigate the consequences of a potential collapse of either the existing shelter or the reactor 4 building, particularly in terms of confining the radioactive dust that would be produced by such a collapse. Broadcasting from online webcam of the Chernobyl Nuclear Power Plant (CNPP) in Pripyat, Ukraine. The operational phase of the New Safe Confinement involves the demolition of the unstable structures associated with the original Shelter Structure. However, the structure was moved using hydraulic jacks, beginning the 327-metre (1,073 ft) move on November 14, 2016, and finishing on November 29.[8][18]. The conceptual designers of the New Safe Confinement recommended the use of rope operated grabs for the first 0.3 metres (11.8 in) of pile excavation for the Chernobyl site. The tools selected for the demolition process were selected based on a number of factors including minimization of individual and collective radiation exposure, the amount of secondary waste generated, the feasibility of remote operation, the cutting efficiency, fire safety, capital cost and operating costs. The steel used in the construction of the tubular members has a yield strength of no less than 2,500 kg/cm2 (250 MPa; 36,000 psi). These included road and rail connections, site services (power, water, drains, and communications), facilities for workers (including medical and radiation protection facilities), and the installation of a long-term monitoring system. Between 2004 and 2008, workers stabilized the roof and western wall of the shelter. The New Safe Confinment at the Chernobyl nuclear power station. The webcam, which is directed towards the construction site of the New Safe-Confinement - "The Arch”. swf.flashVar("vid","rtmp://live.chnpp.gov.ua/strmr-sp1430/orig-sp1430"); Playing next Further upgrades to the area in preparation for New Safe Confinement construction were completed in 2010. The Shelter Structure was moderately successful in confining radioactive contamination and providing for post-accident monitoring of the destroyed nuclear reactor unit; it has been estimated that up to 95% of the original radioactive inventory of reactor 4 remains inside the ruins of the reactor building.[9]. The arches are constructed of tubular steel members and are externally clad with three-layer sandwich panels. Bay 1 was slid East to accommodate the construction of arch 3 and Bay 2.

The New Safe Confinement (NSC) aims to prevent the release of radioactive material for the next 100 years. [17][18][19], Two options were initially considered for moving the structure: hydraulic jacks to push the structure forward, or pulling the structure with large, multi-stranded steel cables. The first option would require the relocation of the hydraulic jacks after each push. [15] Workers in the 'local zone' carry two dosimeters, one showing real-time exposure and the second recording information for the worker's dose log.
