Japanese Nuclear Reactor – Fukushima Power Plant
This week, Japan was hit by an earthquake and tsunami that has left thousands of people lost and feared dead. At the same time, two nuclear reactors at the Fukushima Power Plant are at risk of a meltdown after their cooling systems were knocked out. These Boiling Water Reactors (BWRs) keep their fuel cool and safe by continuously flowing water through their cores. These cooling system failures mean that the fuel is at risk of over-heating, which could lead to a core meltdown and a radiation leak.
