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.
