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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

The total neutron cross section of Sm152 has been measured in the energy range from 6.84 to 9.18 ev with the BNL crystal spectrometer using the Be (1231) crystal planes as a monochromator. The resonance at 8.036 ev was fitted to a Breit-Wigner single-level formula by the method of shape analysis. Since the target nucleus is even-even, I = 0, and hence the statistical weight factor g = 1. Consequently all Breit-Wigner parameters can be determined from the total cross section measurements alone. The resonance parameters obtained from the analysis are: E0 = 8.036 ± 0.010 ev, σ0 = 210,000 ± 2000 barns, Γ = 0.201 ± 0.008 ev, Γγ = 0.071 ± 0.010 ev, and Γn = 0.130 ± 0.005 ev.
