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 prompt-neutron-induced fission spectra of 233U, 235U, 239Pu, and 240Pu were measured relative to the prompt-spontaneous-fission-neutron spectrum of 252Cf. Analysis of the measured values indicates that the incremental average-fission-neutron energies relative to a 252Cf fission-neutron spectrum of Maxwellian form with an average energy of 2.13 MeV are −123 ± 30 (233U), −157 ± 24 (235U), −76 ± 29 (239Pu), and −46 ± 29(240Pu) keV.
