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.

IAEA promoting nuclear energy with G20
The International Atomic Energy Agency launched a collaboration with the Group of 20 this week to highlight the key role that nuclear energy can play in achieving energy security and climate-change goals.
The aim of this first-of-its-kind partnership with G20—the world’s largest economic group—is to build momentum for nuclear power. This is the first time the IAEA has presented to G20 on issues relating to nuclear power.

Neutron coincidence measurements of plutonium samples with uncertainties <0.5% could reduce the amount of costly destructive analysis required for nuclear material accountancy in plutonium handling plants. The ratio of (, n) emission to spontaneous fission neutron emission, , of plutonium samples is important to the interpretation of neutron coincidence measurements. When the “known alpha” analysis method is used, an error on the value propagates to approximately the same percentage error on the measured plutonium mass. Molality data of Charrin and the SOURCES code have been used to update the calculation of for both pure plutonium nitrate solutions and plutonium/uranyl nitrate solutions of different concentrations and acidity. This paper gives equations for the density of the solution as a function of heavy metal concentration and for the weight factors that can be used in the analysis of neutron coincidence measurements.
