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.

The ROSA-III program has conducted system effects tests on the thermal-hydraulic response of a boiling water reactor during a loss-of-coolant accident. The performance of the emergency core cooling systems was of particular interest. As part of this program, ten tests were conducted with (a) a simulated pipe rupture located at the recirculation pump suction line, (b) a spectrum of break area ranging from 0 to 200% of scaled pipe cross-sectional area, and (c) an unavailable high-pressure core spray (HPCS) system. In these tests the pressure vessel depressurized (a) due to the actuation of the automatic depressurization system for scaled break areas of <5%, (b) due to uncovery of the inlet of the broken recirculation pump suction line for scaled break areas of >50%, and (c) due to both for the intermediate break areas between 5 and 50%. Vessel depressurization enabled the injection of emergency core coolant from the low-pressure core spray and low-pressure coolant injection system and thus led to safe recovery without HPCS. The behaviors of the vessel pressure, core mixture level, and core temperatures were fairly well reproduced by the THYDE-B1 code, based on simplified lumpedparameter models for the wide spectrum of break areas investigated.
