Photos released of Fukushima reactor probe

Japan's nuclear regulators have released photographs of their first on-site investigation of the 2011 accident at the Fukushima Daiichi nuclear power plant.

The new investigation by the Nuclear Regulation Authority is focused on whether the March 11 earthquake damaged the plant's No. 1 reactor's cooling system before the arrival of a massive tsunami.

The authority released 4 photographs shot on the 4th floor of the No.1 reactor building. They were shot by 5 officials from the authority's secretariat last Friday.

The photos show the cooling system's red water tank and air-conditioning system in which parts were displaced and damaged.
