The government's nuclear safety agency has ordered Tokyo Electric Power Company to closely monitor radiation and water levels in tunnels outside the turbine buildings for 3 damaged reactors.
The water was found leaking from the reactors and is filling tunnels linking the reactor buildings to outside the damaged Fukushima Daiichi power plant.
Radioactivity on the surface of water found just outside the turbine building of the Number 2 reactor is particularly high, at over 1,000 millisieverts per hour.
The nuclear agency told reporters on Tuesday that as far as it is aware, the tunnels are not flooded, and are not directly connected to the sea.

Among other things in the video, they’re pumping less water into reactor #2, so not as much contaminated water is produced. Naturally, as a result, the temperature has increased somewhat.
