One year after the disaster core details not known
One year after the disaster at the Fukushima Daiichi nuclear power plant, core details relating to the accident are still not known, including from where a large amount of radioactive material was released.Following the March 11th earthquake and tsunami, nuclear fuel melted at the No.1, 2, and 3 reactors of the plant. Many people were forced to evacuate because a large amount of radioactive material was released across a wide area. The nuclear accident seriously affected Japan's entire society and economy.Various measures to cool the reactors and contain the release of radioactive material were taken, and such measures made the situation more stable.Accident study teams of Tokyo Electric Power Company, the Japanese government, and private groups looked into the reason the severe disaster happened. They have revealed insufficient measures against tsunami and inadequate responses at the time of the accident.But details remain unclear, including from which part of the plant the large amount of radioactive material was released, and how much material was spread in the air or at sea.And there's another core item still unconfirmed. The utility firm says the earthquake itself did not affect major safety facilities and equipment. However, the high radioactivity at the site does not permit confirmation of the claim.
