US Nuclear experts deployed to Fukushima
US deploys nuclear experts to aid in Fukushima nuclear crisis. Read On.
While Japan is well prepared to brace itself against earthquakes, the tsunamis which followed were responsible most of the damage done. As the Japanese pick themselves up after the earthquake, Japan might be facing it's greatest challenge yet in a decade.
The US Nuclear Regulatory Commission said that it has sent two experts to Japan, where authorities were seeking to calm fears of a reactor meltdown. The 8.9-magnitude earthquake damaged the nuclear reactor's cooling systems, and workers are now pumping seawater into the reactor in an attempt to cool it down.
Authorities said that an earlier explosion was not due to a meltdown. Instead, it was due to a buildup in gas pressure as workers pour water onto the reactors.
The two experts sent are experts in boiling water reactors, which are used at the Fukushima nuclear power plant.
Boiling water reactor
A nuclear meltdown occurs when a severe failure of a nuclear power plant system prevents proper cooling of the reactor core. The nuclear core heats up to an extent that it melts through its container. A meltdown is considered very serious as radioactive materials could be released into the environment.
