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.

Analyses were performed on three mixed-oxide fuel pins. Two were irradiated in a fast flux, one in an epithermal-neutron flux. The compositions of the corrosion product phases in the fuel-cladding gaps of the different pins were similar. The phase was essentially a mixture of metal oxides, with chromium oxide the main constituent. Cesium chromate, if it formed at all, was present in only small amounts. Oxides of iron and nickel were not detected, which suggests that the oxygen potential in the gap did not exceed that for the FeCr2O4 formation. Metallic fragments in the phase resulted from mechanical interactions involving the phase and cladding grains whose boundaries had been weakened by intergranular corrosion. Chromium and manganese were lost from the inner cladding surface of all three pins. Titanium loss also occurred from the two pins clad with titanium-stabilized steel. A grain boundary phase depleted in chromium was present at the inner cladding surface of one of the pins irradiated in a fast flux. The phase that was associated with intergranular attack occurred in advance of the corrosion front.
