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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

A best-estimate small-break loss-of-coolant accident (SBLOCA) analysis of a four-loop pressurized water reactor nuclear power plant is conducted using the computer code RELAP5/MOD2. A plant-specific RELAP5 model is developed, and steady-state operating conditions are calculated. The steady-state model is then employed to obtain SBLOCA scenarios for different break sizes. Transients resulting from the different breaks are studied to determine the limiting break size and obtain comprehensive transient scenarios. The effect of the hydraulic diameter on the transient behavior, related to the steam generator U-tubes, is also observed. The relationship between the break size and the peak cladding temperature is obtained. The study indicates that as the break size increases, a smaller core inventory instigates heatup during core boil-off.
