IEA report: Challenges need to be resolved to support global nuclear energy growth
The International Energy Agency published a new report this month outlining how continued innovation, government support, and new business models can unleash nuclear power expansion worldwide.
The Path to a New Era for Nuclear Energy report “reviews the status of nuclear energy around the world and explores risks related to policies, construction, and financing.”

Duplex coated fuel particles consist of two discontinuous layers of pyrolytic coating. Theoretical advantages of the layered construction appear substantiated in irradiation tests. The inner coating is applied at temperatures of 1400 C to 1750 C, and the high-density, more graphitic final coating is applied at 1800 to 2200 C. Coating micro-structure may be varied from a rough-surfaced highly oolitic conical pyrolytic to a smooth, glossy fine coned pyrolytic. The force necessary to crush these particles is inversely proportional to pyrolytic cone length. Irradiation of Duplex particles at temperatures up to 1200 C and bum-up s to 30 atom percent show a steady Kr88 of 10-5.
