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 burst initiation time and emission rate of delayed neutrons for the Godiva I assembly in the presence of a weak neutron source, which is 5[c-slash] above prompt criticality, were calculated using an analog Monte Carlo method. The initiation time of the simulation is consistent with the result of the experiment. The calculated emission rate of delayed neutrons is included, and an extended probability model of the initiation time is derived based on point kinetics, which well explains the experimental measurement.
