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.
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.

ANS members approve amendment adding YMG rep to board of directors
The American Nuclear Society will include a representative from the Young Members Group on its Board of Directors after ANS members voted this week overwhelmingly in favor of amending Article B6 of the ANS bylaws. The change was mandated by Objective Outcome 5 of the ANS Change Plan 2020.
To keep the number of directors at 16, the approved amendment decreased the number of non–U.S. resident directors from three to two.

Chemical vapor infiltrated (CVI) silicon carbide fiber reinforced-silicon carbide matrix (SiC-SiC) composite is a relatively new material and has come under increased scrutiny as an attractive material for nuclear applications. In these materials, the interplay between fiber and matrix leads to enhanced fracture toughness. However, due to the inherent directionality of the fibers, under-standing the mechanical and thermal performance is complex and requires careful characterization. At General Atomics, a laboratory has been established to develop these materials for a range of applications, in particular for the Energy Multiplier Module (EM2), which is a gas-cooled fast reactor.In this paper, the program of work that is being undertaken to fabricate and characterize SiC matrix com-posites is discussed. For mechanical testing, specialized fixtures have been developed to hold the thin ceramic composite specimens. For thermal testing, the purge gas species and flow rate have been identified as important parameters. Initial results on planar samples have been performed on SiC-SiC samples and hot pressed SiC samples.
