Kentucky legislature sends nuclear bills to governor
Kentucky’s Republican-majority legislature passed a bill this past week that could bring nuclear energy to the “coal-is-king” state as lawmakers broadly seek solutions to reduce carbon emissions. The bill went to Democratic Gov. Andrew Beshear on Monday for final approval.

As a part of the ARIES-CS compact stellarator power plant study, a modular, helium-cooled, T-tube divertor design that can accommodate a peak heat load of 10 MW/m2 has been proposed. Detailed analyses have been performed using the FLUENT[registered] CFD software package to evaluate the thermal performance at the nominal design and operating conditions. Extremely high heat transfer coefficients (>40 kW/(m2-K)) have been predicted. An experimental investigation has been undertaken to validate the results of the numerical simulations. A test module which closely simulates the geometry of the proposed He-cooled T-tube divertor has been tested using air as the coolant while maintaining the same non-dimensional parameter ranges as the He-cooled T-tube divertor design. Axial and azimuthal variations of the local heat transfer coefficient have been measured over a wide range of operating conditions. The experimental data closely match the model predictions. The results of this investigation show that the model can be used with confidence in future design analyses of the T-tube divertor, as well as similar types of gas-cooled high heat flux components.
