Development and design of a UF(sub 6) gas pressure meter for 42 mm pipes

摘要

X-ray fluorescence (XRF) has proved to be a feasible method of measuring the pressure of UF(sub 6)-gas for enrichment verification purposes. Complications will arise under extreme conditions, such as high uranium deposit to gas ratios, pipe diameters smaller than 40 mm and pressures less than 100 Pa. This report presents an experimental analysis of the XRF method for design worst case conditions for 42 outer diameter cascade-to-header pipes and the development of a prototype measurement device. This prototype is integrated in the construction of the enrichment verification system. (orig.). (Atomindex citation 28:005287)
