In transition: Commercializing fusion power
Commercial fusion power is closer than ever. There are now around 30 U.S. fusion companies, several of which claim to be on track to connect to the grid as early as the 2030s.
Tokamak and laser inertial confinement approaches benefit from decades of research at facilities such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and ITER, with alternative concepts including stellarator, magnetic mirror, and Z-pinch confinement also making notable progress as private and government funding for fusion increases.

The neutron transport equation for a localized isotropic burst of neutrons in plane geometry can be represented as an infinite set of equations. Kholin has solved these equations, expressing the neutron density in terms of an infinite series of integrals. These integrals are evaluated numerically by either a recursion relation or a Chebyshev-Gauss quadrature approximation. The neutron density found by this method serves as an analytic “benchmark” to which other solutions to the time-dependent transport equation can be compared. A new closed form of the solution is also derived.
