N2 - A study was performed to determine the surface roughness of the corrosion layer on aluminum clad booster fuel plates for the proposed Gas Test Loop system to be incorporated into the Advanced Test Reactor (ATR) at the Idaho National Laboratory. A representative sample coupon autoclaved with the ATR driver fuel to produce a protective aluminum hydroxide coating on the cladding surface was obtained. The coupon was analyzed using optical profilometry to determine the mean surface roughness, a parameter that can have significant impact on the coolant flow past the fuel plates. This information was used to specify the surface finish of flow test plates for a hydraulic flow test model. The purpose of the flow test is to obtain loss coefficients describing the resistance of the coolant flow paths, which are necessary for accurate thermal hydraulic analyses of the water-cooled booster fuel assembly. A sensitivity study was performed to assess the effect of the fuel plate surface roughness on coolant temperature, coolant flow rate, and fuel temperature for the booster fuel assembly in the current Gas Test Loop design.
