what actually happened at chernobyl

this video was so dang fun to research which of course i feel super guilty about because like real people died but after watching the hbo miniseries i knew there was more to the science of this i039ve also heard a lot of stuff from both credible and non-credible sources that just doesn039t hold up to scrutiny the idea of the quotgraphite tipped rodsquot for example is just a simplification for broad audiences but i039ve also heard smart folks talk about how rbmk reactors have a positive fuel temperature coefficient which is not true no nuclear reactors do since fuel that reacted more as it got hot would be the kind of thing that would explode every time however for a moment because water had become such a vital part of the neutron absorption in the reactor it did have a positive temperature coefficientmeaning that getting hotter made it hotter which made it hotter which made it hotter that039s a coefficient for the entire reactor and it039s due to the quotpositi

the blue light is known as cherenkov radiation it is similar to a sonic boom but instead of an object travelling faster than the speed of sound a charged particle is travelling faster than the speed of light in a medium in this case the speed of light in water is roughly 75 the speed of light in a vacuumit tests the time-dependent properties of the fuel engineers use that data to predict what would happen if there were an accident at a large reactorcherenkov radiation also known as vavilovcherenkov radiationa is electromagnetic radiation emitted when a charged particle such as an electron passes through a dielectric medium at a speed greater than the phase velocity of light in that medium the characteristic blue glow of an underwater nuclear reactor is due to cherenkov radiationessentially when light passes through different materials its speed can be slowed as the photon makes it way through the medium10000th cycle of the annular core research reactorreed college targa i reactor

spectacular new footage shot from a drone flying over the site of the chernobyl nuclear power plant released by the ebrd today shows the latest advances in securing the site of the 1986 accident the video focuses on the arch that will shelter the damaged reactor 4 upon completion in late 2017 it will prevent the release of contaminated material from the present shelter and protect the structure from external impacts such as extreme weather the new safe confinement is the largest structure ever been assembled in the vicinity of a heavily contaminated site and is 110 metres high 165 metres wide and 260 metres wide it is being constructed by the international consortium novarka led by the french companies vinci construction and bouygues travaux publics novarka also commissioned the drone video the construction works on site started in late in 2010 and recently passed another milestone when the two halves of the giant arch were joined once fitted with state-of-the-art equipment for deconstruction the structure will be slid over the damaged reactor making it the largest moveable land-based structure ever built financing of the new safe confinement is provided by the international community and the government of ukraine through the chernobyl shelter fund to date the fund has received some 15 billion from 45 donor countries and organisations the ebrd is the fund manager and the largest donor with contributions of approximately 500 million of its own fundsfor more information about this project and others visit http:wwwebrdcomnewsvideoshtml
