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.

Interactions of neutrons with the iron isotope 57Fe have been studied by measuring gamma-ray production cross sections for incident neutron energies between 0.16 and 21 MeV. Neutrons produced by the Oak Ridge Electron Linear Accelerator impinged on a metallic iron sample enriched to 93% in the isotope 57Fe. The resulting gamma radiation was detected using a 100-cm3 Ge(Li) detector placed at 125 deg with respect to the neutron beam line. A complete description of the experiment is given. Absolute gamma-ray production cross sections were measured for gamma rays corresponding to the 57Fe(n,n′ γ)57Fe, 57Fe(n,γ)58Fe, 57Fe(n,α)54Cr, 57Fe(n,2n)56Fe, and 57Fe(n,p)57Mn reactions. The cross section for the 57Fe(n,2n)56Fe reaction exceeds 1 b for En ∼ 15 MeV, and the cross section for the 57Fe(n,p)57Mn reaction exceeds 0.2 b for En ∼ 9 MeV. A new excited state is postulated for 57Mn to account for observed data. Several new transitions are reported for decay of levels in 57Fe. Measured cross sections are compared with data obtained from the current ENDF/B evaluation.
