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.”

Neutron activation measurements are reported for 44 reactions from 14 materials irradiated in a well-characterized neutron field produced by 40-MeV deuterons impinging on 9Be at the Oak Ridge Isochronous Cyclotron. Foil packets were located at 0 and 15 deg to the beam at 7.62 cm from the source, and additional foil materials were located directly on the deuteron beam stop 6.25 mm from the source. Integral tests were made for 30 reactions using previously measured time-of-flight (TOF) spectra and neutron cross sections, primarily from ENDF/B-IV, extrapolated to 44 MeV. The integral results are excellent, with an overall standard deviation of ±11% for 25 recommended reactions (±14% for 30 reactions), and neutron spectra unfolded with the SAND II code show excellent agreement with TOF measurements.
