Water level falls in No.5 reactor
The Nuclear and Industrial Safety Agency says the coolant level has fallen in the No.5 reactor at the Fukushima Daiichi nuclear power plant.
The Agency had earlier said the No.5 reactor stopped safely during a regular inspection when the massive earthquake and tsunami occurred on Friday.
At the time of the quake, nuclear fuel rods were already in the reactor and workers had to circulate water to cool them down.
But the tsunami damaged a diesel generator for circulating the coolant, allowing the pressure in the reactor to rise.
Workers opened a valve to reduce the pressure.
But the procedure allowed water to evaporate from the valve.
As of 9 PM on Tuesday, the water level was 2 meters above the fuel rods. That was 40 centimeters lower than 5 hours earlier.
The Agency says it can adjust the water levels by using the No.6 reactor's generator, which wasn't damaged by the tsunami. Workers are currently pumping water into the No.5 and No.6 reactors.
