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.

Following the Three Mile Island accident, a number of suggestions were offered for improving the safety of nuclear power plants. Many of these approaches involve increased dependence on complex and sophisticated safety systems and control technologies. An alternative approach to increased safety is explored; this approach involves the maximization of inherent safety features and minimization of safety and control system action. Specifically, the effects of changing pressurizer size and surge line configuration are examined to determine if the operation of the power-operated relief valve (PORV) could be eliminated during a turbine trip transient in a pressurized water reactor. The study is accomplished using the RETRAN-02 thermal-hydraulic analysis code. The results show that the opening of the PORV could be eliminated if the pressurizer size was doubled and the PORV setpoint increased slightly.
