Atomic power's share of the global electricity supply is at the lowest level since the 1980s following the shutdown of Japan's reactors after the Fukushima disaster, and may fall further without major new plant construction.
The forecast is one of the main conclusions of the World Nuclear Industry Status Report 2014, a draft copy of which was passed to Reuters before general release later Tuesday.
The report paints a bleak picture of the industry more than three years after the March 11, 2011, earthquake and tsunami triggered the meltdowns of three reactors at Tokyo Electric Power Co's Fukushima No. 1 power plant.
