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.

Calculational models were developed for estimating the transport of sodium vapor and the relatively large (≥10-µm) fuel particles resulting from a fuel-coolant interaction to the secondary containment in an LMFBR core disruptive accident. Following the formation of a large sodium vapor bubble resulting from a fuel-coolant interaction, a potential sequence of events was analyzed. This analysis covers bubble condensation, bubble rise time, aerosol fallout during the bubble rise, gas flow rate through the cover, cover-gas escape during the bubble rise, bubble and cover-gas mixing, and aerosol escape to the secondary containment. Two parametric calculations were made for specified accident conditions for a 1000-MW(e) LMFBR conceptual design. The bubble did not condense in this analysis. Results of the analysis indicated that 2 and 10% of the fuel that took part in the fuel-coolant interaction eventually reached the secondary containment for the two assumed flow areas through the cover, i.e., 0.1 and 1.0 ft2, respectively.
