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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Following the Fukushima accident, research of accident tolerant fuel (ATF) and cladding materials began in order to improve the nuclear power plant safety following a Beyond Design Basis Accident (BDBA). National laboratories, industry, and universities are involved in this activity. Researchers at the University of Wisconsin are simulating BDBA’s to examine the effect of ATF cladding material using MELCOR. Use of alternate cladding materials (FeCrAl) and potential operator recovery actions have been previously studied. In this work, we examine the effect of FeCrAl coating on Zircaloy using a special version of MELCOR-1.8.6 (YU) developed by Idaho National Laboratory. This MELCOR version allows one to examine the effect of cladding coatings (Cr, FeCrAl) assuming appropriate thermo-physical data are available. FeCrAl is used as a first application of this modeling approach for clad coatings. Using a Short- Term Station Blackout (STSBO accident sequence shows that overall accident progression is quite similar to events without a coating, except for the start rapid core heatup, degradation and significant hydrogen generation. These events are delayed for more than an hour compared to nominal conditions.
