Fast-breeder nuclear reactor,Monju is expected to be re-started.
Current JP PM Kan decided to abandon because it’s way more risky than light-water reactor plant,such as Fukushima plant.
Monju uses natrium for its cooling system but it explodes when it leaks unlike water.
They invested 2.4 trillion yen into this crap but it has never worked properly.Since they dropped 3.5t of a part into the reactor 8/26/2010,it has been stopped.The reactor is highly likely to be damaged because of this accident but there is even no way to check it.
Therefore the attempt to re-start is almost insane.
