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.”

Adjoint transport calculations provide an efficient means for determining the response of various targets to external sources of radiation. In the present paper, the fission response of a small, cylindrically symmetric target to a plane-incident beam of neutrons is determined through three techniques: (a) a discrete summation using EQN quadratures, (b) a discrete summation using Lobatto quadratures, and (c) an exact integral of a spherical harmonic interpolation of EQN angular fluxes. To calculate the fission response of the sample target to a reasonable degree of accuracy, the first method requires the use of quadratures of order at least S16, while the second method requires only S8. The general utility of the third method is hampered by a rapid increase in complexity with increasing quadrature order; however, for the present example, in which a low-order quadrature solution provides reasonably accurate scalar fluxes, interpolation of S2 angular fluxes yielded a response of comparable accuracy to the S8 Lobatto solution.
