Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

High resolution measurements of the total neutron cross section from 200 eV to ∼50 keV in natural copper have been performed using time-of-flight techniques. From the R-matrix analysis of the data, values of E0, Γn, Jπ of resonances, strength functions, and average level spacings are obtained. For in units of eV−1/2 were obtained. Similarly, the average level spacings are determined for 63Cu〈D〉 J = 1 = (2.38 ± 0.38) keV, 〈D〉J = 2 = (3.57 ± 0.70) keV and for 65Cu〈D〉J = 1 = (3.85 ± 0.88) keV and 〈D〉J = 2 = (5.0 ± 1.2) keV.
