In the past week the Hamaoka nuke plant, east of Tokyo, was shut down, at the request of the government.

The reason was that the plant sat on two fault lines, and scientists expect a 8+ quake. The plant was not built to withstand such a earthquake.

Now Chubu Electric Power Company says they’ve discovered that at least 400 tons of salt water has gotten into the reactors.  Salt water can damage the reactors and coolant pumps.  They think the salt water is coming from a damaged water line connected to a turbine room.
