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 effectiveness of an adaptive acceleration method is studied for the inner iterations in some neutron diffusion codes. The acceleration method can be easily incorporated in the process of the general first-order stationary linear iterations. The effectiveness is shown theoretically in the case when the iteration matrix is nonnegative definite. The numerical results of its applications to the successive over-relaxation and alternating direction implicit iterations are presented. It is shown to work effectively even when the fixed parameter of the iteration is not chosen optimally. Some variants of the acceleration method are also given.
