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.

BREAKING NEWS: Trump issues executive orders to overhaul nuclear industry
The Trump administration issued four executive orders today aimed at boosting domestic nuclear deployment ahead of significant growth in projected energy demand in the coming decades.
During a live signing in the Oval Office, President Donald Trump called nuclear “a hot industry,” adding, “It’s a brilliant industry. [But] you’ve got to do it right. It’s become very safe and environmental.”

A technique for calculating an approximation to the time-dependent power of a boiling water reactor (BWR) during steady-state, low-amplitude limit-cycle oscillations is described. An approximate solution is obtained from the application of Galerkin’s method to a BWR dynamic model consisting of the point-kinetics equations and the power-to-reactivity feedback transfer function; such a feedback transfer function can be obtained from linear frequency domain stability codes, such as the LAPUR code. The approximate solution technique is described, and comparisons of approximate solutions with numerical results and measured data are given. It is concluded from these comparisons that the application of Galerkin’s method to the equations obtained from this particular BWR dynamic model can be used to extend results from a linear frequency domain stability code to calculate nonlinear, time-dependent reactor parameters during low-amplitude limit-cycle oscillations.
