* FUKUSHIMA NUCLEAR ACCIDENT IS THE MOST SERIOUS AND AFTER CHERNOBYL *
*
/ Ecologists in Action has reported that the situation in reactors 1 and 2
central Fukushima (Japan) is very serious. The explosion in the reactor 1
has led to the escape of radioactivity while
operators working to cool the core number 2. For
Greenpeace is a serious situation that comes to
aggravate the effects of the earthquake. / *
Fuskushima The NPP comprises six water reactors running
boiling and two more under construction, also
boiling water. Reactors 1 and 2, suffering from serious problems, started functioning
March 26, 1971 and July 18, 1974,
respectively, and have electrical power of 460 MW and 784 MW. The reactor
Fukushima I is therefore similar to that of the nuclear power GaroƱa
(Burgos). In the central
boiling water and cooling water boils in the reactor core and steam
removed from the containment dome some pipes that run through several
central units to reach the turbines, where electricity is generated
. The stability of the reactor strongly depends
will control the amount of vapor in the nucleus, which depends on pressure and temperature
.
The situation may be more serious because it is struggling to cool the reactors
but is not guaranteed to be able to maintain the nuclear reaction under control
. The work of the operators is very
difficult because the level of radioactivity was multiplied by a thousand
in the control room, so that workers are
performing operations may be receiving radiation doses above the permitted level
, increasing stress and the possibility of making mistakes
The explosion produced in Fukushima I shows the failed attempts
reactor cooling. In plants the
boiling water reactor steam level is key to safety, because the
excessive amount of steam produced in the reactor would make
decrease the possibility of cooling the radioactive core, which will increase
risk and accident. In this type of plant, pipes
of radioactive steam out of contention and walk several units
the plant, so that the explosion of a pipe makes the radioactivity
immediately escape into the environment. The
to avoid an accident with core meltdown and the resulting
uncontrolled nuclear reaction that passes through cool
get two reactors at Fukushima I and II. If this does not happen in the next
hours, the consequences could be catastrophic.
has been necessary to evacuate 46,000 people living within a radius of 20
km around the plant. Certainly
Emergency Plans English Nuclear power plants provide only action around
the 10 km radius of nuclear weapons. All this adds to problems
generated by the earthquake. Following this accident the most sensible for the Japanese Government is abandoning
projects
new reactors to be closed and phased out of the 55 nuclear reactors operating in Japan
