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.

The parameters of a uranium-enriching cascade, i.e., the cut and the separation factor, are considered to be fluctuating stochastically. The covariance matrices of the total uranium flow and 235UF6 flow were derived by the classical stochastic theory for evaluating the effect of stochastic fluctuations of these parameters to steady-state plant performance. Also the stationary random process theory is applied to the kinetic equations of the cascade, and the autocorrelation function of the 235UF6 flow and enrichment is derived for evaluating the time behavior of the plant performance caused by random fluctuation of these system parameters. Numerical values illustrate the response of product flow and enrichment to the fluctuations, which are both time independent and dependent, of the cut and the separation gain of stages and centrifuges. These data lead to a conclusion concerning the tolerances of centrifuge parameters and stage controllers.
