What has now become of Chernobyl disaster
Many of you have heard what happened in Chernobyl- located North of Kiev, Ukraine and near the south border of Belarus. I was born in the year 1986- when it happened and always interested in the history of my country. (Russia).
Here is a script of what exactly happened from: www.world-nuclear.org/info/chernobyl/inf07.html
“The interaction of very hot fuel with the
cooling water led to fuel fragmentation along with rapid steam production and
an increase in pressure. The design characteristics of the reactor were such
that substantial damage to even three or four fuel assemblies can – and did – result in the destruction of the reactor. The
overpressure caused the 1000 t cover plate of the reactor to become partially
detached, rupturing the fuel channels and jamming all the control rods, which
by that time were only halfway down. Intense steam generation then spread
throughout the whole core (fed by water dumped into the core due to the rupture
of the emergency cooling circuit) causing a steam explosion and releasing
fission products to the atmosphere. About two to three seconds later, a second
explosion threw out fragments from the fuel channels and hot graphite. There is
some dispute among experts about the character of this second explosion, but it
is likely to have been caused by the production of hydrogen from
zirconium-steam reactions. The
graphite (about a quarter of the 1200 tones of it was estimated to have been
ejected) and fuel became incandescent and started a number of fires,
causing the main release of radioactivity into the environment.”
