A leak of contaminated water has been discovered from a pipe connected to a caesium adsorption device at the damaged Fukushima Daiichi nuclear power plant in Japan. The leak has been stopped and Tokyo Electric Power Company (Tepco) said it will check soil beneath the pipe for contamination.
Tepco said that at about 8.52am on 7 February a worker from a contracted company found that water was leaking from the vent opening of the second cesium adsorption device installed on the east wall of the high-temperature and high-pressure incinerator building. The vent is for discharging hydrogen generated within the adsorption device. The second cesium adsorption device was currently out of service and was undergoing flushing work with filtered water for valve inspections.
At around 9.10am, the main valve for filtered water was closed, and at around 9.16am, Tepco confirmed that the water had stopped leaking.

Tepco estimates that about 5.5 tonnes of water leaked from the pipe, which may contain 22 billion becquerels of radioactive materials, such as caesium and strontium. ...
