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.”

A brief review is presented of the development and evaluation of coated-particle fuel for the Peach Bottom high-temperature gas-cooled reactor. The results of extensive thermal and irradiation tests on the Peach Bottom fuel materials have shown them to be adequate for a 3-yr core life of this reactor. Consideration of the mechanisms that could lead to coating failure under irradiation has shown that swelling of the carbide particle from fission-product accumulation and shrinkage of the pyrolytic-carbon coating from fast-neutron and fission-recoil effects are the principal contributors to coating failure. A “Triplex” pyrolytic-carbon coating has been developed to overcome these effects. This coating consists of a spongy layer of pyrolytic carbon overcoated with successive layers of laminar and columnar pyrolytic carbon.
