Steam has been spotted rising from a damaged building inside Japan’s crippled nuclear power plant in Fukushima.
The company responsible, Tepco, said it may have been rain reacting with a hot containment vessel to produce the suspicious looking steam.
The reactors damaged in a massive earthquake and tsunami in 2011 led to radiation leaks into the sea and air.
Tepco are still struggling to limit the damage to the environment two years on from the disaster. They have been flushing water over the damaged reactors to keep them cool since the accident occurred creating enough contaminated water to fill one Olympic-sized pool per week.
