Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

This paper deals with the well-known problem of calculating derivatives and perturbations of the multiplication factor and reaction rates by the Monte Carlo method. The central point of the problem is the fact that the fission source spatial distribution depends on the solution of the neutron transport equation. Thus, whatever perturbation of material or geometrical parameters happens, it will lead to a perturbation of the fission source spatial distribution. Ignoring this can cause significant errors. There have been proposed several techniques to consider the aforementioned fact. This paper presents another possible solution.
