A team of nuclear experts formed by the International Atomic Energy Agency on Monday started its activities in Japan to review the country's ongoing efforts to scrap the crippled reactors at the Fukushima No. 1 nuclear power plant.

It is the first IAEA mission to Japan focusing on decommissioning. The 12-member team will also look into the recent radioactive water leaks and electricity supply disruptions at the plant — mishaps occurring more than two years after the devastating nuclear crisis started.

Team leader Juan Carlos Lentijo, director of the IAEA Division of Nuclear Fuel Cycle and Waste Technology, said the recent troubles are among the topics to be discussed during the one-week mission.
