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.

How to talk about nuclear
In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

The delayed-neutron fractions for thermal fission of 235U, 239Pu, and 233U were measured and found to be The technique used to perform the measurements was intrinsically simple and involved making only relative measurements. The basic approach was to compare the neutron production rate of a thin fissile sample in a thermal-neutron beam with the delayed-neutron production after an abrupt termination of the beam. The work was greatly enhanced through the use of a modified long counter that was developed at the Los Alamos Scientific Laboratory. The results of this work are in essential agreement with the presently accepted values, which were reported in 1957 and were measured by using a different technique than that used here.
