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.

A measuring device for measuring the mass flow of nonsteady-state two-phase flows has been developed based on the principle of rotating flow machines. Two versions of the device [true mass flowmeter (TMFM) 2.5 with a measuring range of 2.5 kg/s, and TMFM 50 with a measuring range of 50 kg/s] were used to study the measuring accuracy and the field use of the system. While the measurement errors of TMFM 2.5 are within ±2.2% of the maximum flow, it is possible with the TMFM 50 to reduce the measuring error to ±1.5% (quality x<l%) and ±0.5% (quality ≥ 1%). This implies that the accuracy in measuring two-phase mass flow is practically identical with that obtained in single-phase flow by familiar standard measuring techniques.
