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 factorized kernel technique for solving neutron transport problems with arbitrary anisotropic scattering is studied and developed numerically. A new derivation that is simple and straightforward is given for the factorization formulas. One-dimensional slab and two-dimensional infinite parallelepiped problems are studied, and extensive results with several useful comparisons are given. Nonclassical Gaussian quadrature rules are constructed with higher order and precision. Different criteria are given to check these rules and calculate the absolute relative error. Several possible applications and extensions are proposed, and the advantages of this approach are demonstrated.
