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.

Samples used in Doppler-effect measurements in fast critical assemblies distort the flux in their vicinity. For fissile samples whose Doppler effect depends strongly on spectrum, this distortion may strongly affect the measured results. An integral transport method for computing distorted real and adjoint fluxes is developed and the fissile-sample Doppler measurements in a fast critical assembly, ZPR-6 Assembly 7, are analyzed. It was found that the local flux distortions strongly affect the results and for a PuO2 sample even change the algebraic sign of the Doppler effect.
