KIEV, April 26 (Xinhua) -- Tuesday marks the 30th anniversary of the Chernobyl nuclear disaster in today's Ukraine, but many painful lessons have not been learned.
In March 2011, the Fukushima Daiichi nuclear plant in Japan was disabled after explosions, a top-level disaster.
Some Ukrainian nuclear safety experts believe that the Fukushima tragedy was preventable given the Chernobyl experience, but human negligence had left the plant unprepared for the earthquake and tsunami.
