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.

Kentucky legislature sends nuclear bills to governor
Kentucky’s Republican-majority legislature passed a bill this past week that could bring nuclear energy to the “coal-is-king” state as lawmakers broadly seek solutions to reduce carbon emissions. The bill went to Democratic Gov. Andrew Beshear on Monday for final approval.

In order to verify the integrity of the first wall (FW) of the International Thermonuclear Experimental Reactor (ITER) the fabricated Be/Cu mock-ups were tested at the TSEFEY, e-beam facility, in Efremov, Russia. The Be/Cu mock-ups were joined with CuCrZr for a heat sink material among the Cu alloys and 316L austenitic stainless steel (SS316L) tubes for a coolant and then, joined with Be tiles for an armor material. Hot Isostatic Pressing (HIP) was used as a manufacturing method at 1050 °C, 100 MPa for 2 hours for a Cu/SS joining and at 620 °C, 100 MPa for 2 hours for a Be/Cu joining. The high heat flux (HHF) tests were performed for two Be/Cu mock-ups with a 2.5 MW/m2 heat flux and 80 sec durations, which were determined from a preliminary analysis with ANSYS-11. The temperature results from the test showed a good agreement with the analysis results and the fatigue lifetime was evaluated from the strain analysis results.
