Core Thermal HydraulicsData for a novel PWR-type Small Modular Reactor (SMR) are listed below. Neglect control rodsand take coolant physical properties at 300C saturated. Assume the flux distribution corresponding to a simple bare cylindrical core. As required, useappropriate empirical correlations from the module.
(a)Determine the Reynolds number of the flow in the core.
(b)Determine the Darcy-Weisbach (Moody-chart) friction factor for the flow in the core.
(c)Calculate the wall shear stress, and the pressure drop between core inlet and outletof the core.
(d)Determine the pumping power required for the core.
(e)What fraction of the electricity the plant generates is required to pump the coolant through the core?
(f)What will be the heat transfer coefficient between the fuel rods and the coolant?
(g)Determine the cladding external temperature at the axial mid-planefor an average rod. Will this be the highest external cladding temperaturefor that rod? Explain your answer
