A review of workforce trends in the nuclear community
The nuclear community is undergoing a moment of unprecedented interest and growth not seen in decades. The passage of the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act are providing a multitude of new funding opportunities for the nuclear community, and not just the current fleet. A mix of technologies and reactor types are being evaluated and deployed, with Vogtle Units 3 and 4 coming on line later this year, the Advanced Reactor Demonstration Projects of X-energy and TerraPower, and NuScale’s work with Utah Associated Municipal Power Systems to build a first-of-a-kind small modular reactor, making this is an exciting time to join the nuclear workforce.

A new experimental facility at the University of Wisconsin-Madison, the Dual-Advanced Ion Simultaneous Implantation Experiment (DAISIE), has been designed and constructed to examine tungsten surface damage phenomena. These include microstructure formation and erosion due to helium bombardment as well as the retention of hydrogen gas while under the simultaneous bombardment of helium and deuterium ion beams, as would occur in ITER or other deuterium-burning fusion devices. DAISIE features two ion guns angled at 55° to the sample normal. These guns are independent with respect to beam current, allowing for a high degree of control over the separate D and He beams fluxes and fluences and the composition ratio of these ions impinging upon the tungsten sample surface. Preliminary results are available for helium-only implantations at energies of 30 keV to average fluences of 3 × 1018 He/cm2 in tungsten samples at temperatures of 900°C. As in prior experiments, surface damage appears to be highly-dependent on the crystallography of the individual grains. although a distinct set of helium-induced microstructures from past experiments is observed. Erosion yield is consistent with prior, similar helium irradiation experiments at the University of Wisconsin, but exceeds that predicted by physical sputtering yields and other past sputtering experiments.
