WEST claims latest plasma confinement record
The French magnetic confinement fusion tokamak known as WEST maintained a plasma in February for more than 22 minutes—1,337 seconds, to be precise—and “smashed” the previous record plasma duration for a tokamak with a 25 percent improvement, according to the CEA, which operates the machine. The previous 1,006-second record was set by China’s EAST just a few weeks prior. Records are made to be broken, but this rapid progress illustrates a collective, global increase in plasma confinement expertise, aided by tungsten in key components.

Neutron heating sensitivities to cross-section uncertainties were calculated in a controlled thermonuclear reactor (CTR) blanket. For this purpose, the well-known generalized perturbation methods were used. The CTR blanket chosen was representative of current design specifications. Sensitivity profiles were generated for neutron heating in 6Li, 7Li, iron, and niobium to their respective cross sections. Fairly high changes in the neutron heating can be produced by variations in individual cross sections.
