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.

Proposed rule for more flexible licensing under Part 53 is open for comment
The Nuclear Regulatory Commission has published a proposed rule that has been five years in the making: Risk-Informed, Technology-Inclusive Regulatory Framework for Advanced Reactors. The rule, which by law must take its final form before the end of 2027, would let the NRC and license applicants use technology-inclusive approaches and risk-informed, performance-based techniques to effectively license any nuclear technology. This is a departure from two licensing options with light water reactor–specific regulatory requirements that applicants can already choose.

Experiments on fast plasma heating by the relativistic electron beam in the GOL-3 facility succeeds in the creation of a 1015 cm−3 plasma with electron temperature of up to a few keV. The heating is produced due to two-stream instability of the beam that causes high level of plasma microturbulence. The experiments show some specific features of plasma behaviour during the beam injection. The beam-induced turbulence is the reason of non-classical transport processes in the plasma. Anomalies in longitudinal thermal conductivity, resistivity of the plasma and in lifetime of hot electrons are observed. Transition to classical transport coefficients occurs when the plasma turbulence disappears after the beam injection stops.
