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 range of radiological consequences that could result from a multiple steam generator tube rupture event has been examined. Efforts to obtain thermal-hydraulic data for the multiple tube rupture event were only partially successful Lacking a detailed knowledge of the thermal-hydraulic characteristics of a multiple tube rupture event, a three-variable parametric study was performed. Both thyroid and whole-body exposures were determined as a function of integrated primary to secondary flow and integrated secondary relief valve flow. For all cases considered, calculated exposures were below guidelines specified in 10CFR100 and far below a level where injury might be expected. On this basis and considering the conservatism employed in the exposure estimates, it was concluded that a multiple tube rupture event would not endanger the health and safety of the public. Furthermore, it would be overly conservative, in view of the significantly lower likelihood of a multiple tube rupture event, to base primary coolant technical specifications for iodine on a multiple tube rupture event and a limit of a 1.5-rem thyroid exposure at the site boundary.
