Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

A new model is described for nonequilibrium vapor production (flashing) in critical two-phase flow. The model is based on a description of turbulence enhanced thermal diffusivity in the liquid and a Weber number criterion for bubble size. In a quiescent environment, the model reduces to the well-known conduction controlled rate. Results of calculations are compared with flow rate and pressure data from blowdown experiments with various nozzle geometries. The nozzle throat diameters range from 1.8 to 51.0 cm and nozzle inlet conditions vary from water subcooled 30°C to saturated water at 98% vapor volume fraction. The calculations are made with the two-fluid code K-FIX and show very good agreement throughout the entire blowdown.
