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 solubility of nickel ferrite is measured at 423, 473, and 523 K in a pure or oxygenated water system, which is similar to boiling water reactor conditions‚ using a specially designed batch autoclave system. Thermodynamic analysis is performed by a procedure minimizing Gibbs free energy of the system at the final state. On the basis of both the analysis and the experimental results, it is shown that the dissolution mechanism of NiFe2O4 under the condition where no redox reaction takes place consists of both NiFe2O4 dissolution and Fe2O3 precipitation equilibria. The calculated value of the solubility at 423 K using literature values of the thermodynamic data agree with the experimental value, but at 473 and 523 K they deviate somewhat from the experimental ones. By fitting to the experimental results at these temperatures, the thermodynamic data of NiFe2O4 for 473 and 523 K are reanalyzed, and new values are proposed.
