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
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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.

A short review of recent results obtained at the GOL-3-II facility is presented. This facility is an open trap with 12 m long plasma column with a longitudinal magnetic field of 4.5 T in the uniform part and 9 T in the end mirrors. There is the possibility to change the magnetic field configuration. Plasma density can be varied in 1014÷1017 cm−3 range. A microsecond electron beam with total energy of 0.2 MJ is injected into the plasma through the input mirror.
Collective interactions of an electron beam with a plasma and its fast heating are studied at this facility. An efficiency of collective electron beam deceleration up to 40% is achieved in a 1015 cm−3 plasma. The average electron temperature of ∼2 keV at plasma density (1–2) 1015 cm−3 is obtained. With two-stage heating of a dense (∼1016 cm−3) plasma the electron temperature of 300÷500 eV and the ion temperature of 100÷200 eV are reached.
Prospects of experiments on multimirror and «wall» plasma confinement at GOL-3-II facility are discussed.
