ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

G7 pledges support for nuclear at Italy meeting
The Group of Seven (G7) recommitted its support for nuclear energy in the countries that opt to use it at a Ministerial Meeting on Climate in Italy last month.
In a statement following the April meeting, the group committed to support multilateral efforts to strengthen the resilience of nuclear supply chains, referencing the goal set by 25 countries during last year’s COP28 climate conference in Dubai to triple global nuclear generating capacity by 2050.

We developed a cross-section adjustment method based on Bayesian theory for adjusting the independent cross-section set that is given by dividing the cross-section set. While all cross sections have to be adjusted in the conventional cross-section adjustment method, the independent cross-section set can be individually adjusted in the developed method. In addition, the covariance of cross sections that are assumed to be independent of each other is not adjusted in the developed method. The adjusted cross sections and the covariance are the same in both methods. The cross-section adjustment was performed using the criticality of the light water–moderated uranium benchmark. The result shows that the uncertainty of the multiplication factor is reduced from 0.005 to 0.007 Δk/k to 0.003 to 0.005 Δk/k by the developed method. The reduction is smaller than that by the conventional method since the developed method does not adjust the covariance of cross sections that are assumed to be independent of each other.
