New report details impact of nuclear energy in southeastern U.S.
A seminal new report by the Southeast Nuclear Advisory Council and E4 Carolinas has identified the significant economic impact of the nuclear industry within the southeastern United States. The report, The Economic Impact of the Nuclear Industry in the Southeast United States, provides a baseline for future research into the crucial role nuclear power plants play in shaping regional economies and facilitating the shift to clean energy.

Based on thermal computation results obtained using an irradiation behavior analysis code, we have evaluated the effect of oxide-metal ratio on fuel restructuring from the results of postirradiation examinations for the B14 irradiation test fuel, which was a mixed oxide fuel and was irradiated in the experimental reactor Joyo. The thermal computation results showed that fuel restructuring in the stoichiometric oxide fuel was accelerated, though the fuel temperature in the stoichiometric oxide fuel was evaluated as lower than that of the hypo-stoichiometric one. We explained this behavior as follows: first, the fuel temperature decreased due to the high thermal conductivity at stoichiometry; second, the pore migration velocity increased due to the increase in vapor pressure caused by the high vapor pressure of UO3, which was derived from the high oxygen potential at stoichiometry. In addition, our results indicated that the central void diameter strongly depended on not only fuel temperature, but also vapor pressure.
