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.

A vectorized source algorithm was developed for the Electric Power Research Institute light water reactor core nodal code SIMULA TE-E. The existing line successive displacement scheme was replaced by configuring the source for all nodes in a given plane as a single vector that could be computed simultaneously. Power distributions and eigenvalues for all test problems agreed exactly with the original scalar code. A factor of 2 to 7 reduction in execution time was achieved for typical pressurized water reactor problems on the CYBER 205.
