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.

DOE-EM finishes cleanup of legacy Oak Ridge reactor lab site
The Department of Energy’s Office of Environmental Management announced that the 30-foot-long, 37,600-pound reactor vessel from Oak Ridge National Laboratory’s Low Intensity Test Reactor was shipped to EnergySolutions’ low-level radioactive waste facility in Clive, Utah, in late April.

Process of interaction of intense plasma fluxes up to 10 MW/cm2 with solid targets was studied experimentally. It was shown that a dense plasma layer arises near target surface and protects the target from direct effect of an incoming high temperature plasma. Spatial distribution and temporal behavior of the shielding layer depend on the target materials. For a high Z materials (tungsten, copper, stainless steel) dense plasma layer is localized near the surface during all time of the interaction. For a low Z materials (graphite, boron nitrid, plexiglass, aluminium) low dense plasma cloud – “corona” rapidly expands toward incoming plasma flow along the magnetic field lines. The experiments demonstrated effective shielding of the different materials surface from excessive evaporation. Bulk energy of incoming plasma is converted into SXR radiation in near surface layer for a high Z materials and, partially, into target plasma heating for a low Z materials. Measured parameters of plasma shield are used as a benchmark in developing numerical codes to predict a real damage for ITER divertor plates due to hard disruptions.
