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.”

The neutron capture and subthreshold fission cross section of 241Am was measured in the energy range from 10 to 250 keV, using 197Au and 235U as the respective standards. Neutrons were produced via the 7Li(p,n) and the T(p,n) reaction with the Karlsruhe 3-MV pulsed Van de Graaff accelerator. Capture events were detected by a Moxon-Rae detector and fission events by a NE-213 liquid scintillator with pulse-shape discriminator equipment. Flight paths as short as 50 to 66 mm were used to obtain optimum signal-to-background ratio. The capture cross section could be determined with a total statistical and systematic uncertainty of 4 to 10% while the respective values are 13 to 20% for the fission cross section. The results are compared with recent data of other authors, which in some cases are severely discrepant.
