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.

Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The formation of the spectrum of ions leaving the Z-pinch constriction during its compression is considered in the framework of the thermal mechanism corresponding to collisional regimes at high density. This mechanism refers to the heating of all ions due to compression without consideration of the electromagnetic acceleration of any selected group of ions. It is shown that such conditions can be implemented in relatively high-density regimes in which the product of precompression density and radius is n0a0 ≫ 1024 m–3. Neutron yield is analyzed. Possible parameters of a fusion reactor based on a high-density Z-pinch are estimated and found to be extremely high in terms of today’s technology.
