Strong performances across the board
Craig Piercycpiercy@ans.org
Another year, another stellar performance by America’s nuclear plants. We’ve come to expect high capacity factors, and it’s a credit to the men and women of the profession. They’ve made routine something that was unimaginable not so long ago.
The decadal challenge for the nuclear enterprise now is to maintain this high level of operational excellence for the current fleet, while at the same time ushering in a new generation of technologies at scale. It will be a big job—but one that seems more and more likely with each passing day.

Radiation transport integrals containing both forward and adjoint fluxes are amenable to solution by the method of correlated coupling. Existing methods for surface integral coupling of forward and adjoint histories have been extended to volumetric coupling. Within the context of standard Monte Carlo usage, these integral solutions are exact, and the application to perturbation analysis requires no approximation. Coupled forward-adjoint history pairs are initiated at points selected uniformly in the perturbed volume. The energy and angular dependence of each history is dictated by the difference operator of the forward and adjoint transport equations, one equation for the perturbed system and one for the unperturbed system. The volume integral is accumulated as these history pairs score in the respective source or response regions. Some simple systems are analyzed showing that the new method gives comparable results, and a lower variance, as for existing methods. A review of current correlated coupling methodology is given, and suggestions for further study are outlined.
