Around 16:10 5/18/2013, Tepco employee found contaminated water overflowing from this tank again.
It’s assumed to be because the tank has been full since 5/17/2013. Tepco states it was only 4L to have overflowed, radiation level is lower than the detectable level.
Tepco is planning to decrease the water level of the tank.
