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.

Ariz. governor vetoes “fast track” bill for nuclear
Gov. Katie Hobbs put the brakes on legislation that would have eliminated some of Arizona’s regulations and oversight of small modular reactors, technology that is largely under consideration by data centers and heavy industrial power users.

Absolute cross-section measurements for reactions among light-mass nuclei (A < 10) are important in feasibility studies of controlled thermonuclear reactor systems. For a 6Li-d fueled fusion reactor, the 6Li (p,3He)α reaction is of particular interest. The absolute cross sections for this reaction are incomplete and poorly known and have accordingly been remeasured in the range Ep = 3 to 12 MeV. The results support recent measurements below 3 MeV in finding the cross section to be higher in this region than previously supposed. Additional results for the 6Li(p,p)6Li and 6Li(p,p′)6Li* reactions imply the cross sections for these reactions are ∼40% higher than earlier measurements. A plot of the Maxwell-averaged reaction rate parameter, , for the 6Li(p,3He)α reaction is presented as a function of kT, the temperature of a p – 6Li plasma.
