Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The development of a practical and simple on-line void fraction measurement of two-phase flow is of prime interest in applications for nuclear reactor safety research and chemical engineering plants. Experiments were performed at a system pressure of 1 atm. The test sections were made of transparent vertical acrylic pipe with three inner diameters of 1.9, 2, and 2.54 cm. The void fraction was measured by different sizes of side tubes in an air-water two-phase flow; and the void fraction was also compared with the data, which were measured from the liquid holdup between two quick-close valves. The experiment results showed a good agreement for void fractions <0.3, but the error could be large when the flow was in the slug regime.
