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 subthreshold fission cross section of 240Pu was measured in the energy range from 10 to 250 keV, using 235U as a standard. Neutrons were produced via the 7Li(p,n) and T(p,n) reaction with the Karlsruhe 3-MV pulsed Van de Graaff accelerator. Fission events were registered by detecting fission neutrons with an NE-213 liquid scintillator with pulse-shape discriminator equipment. The high neutron flux available at flight paths of ∼67 and 135 mm allowed for a statistical accuracy of 1 to 3% together with a moderate energy resolution of ∼10 to 20 ns/m. The overall accuracy achieved is between 7 and 9%. The data show a distinct structure in the cross section, as indicated by poor statistics in previous measurements.
