Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

Thermal interaction during the Three Mile Island Unit 2 2-B coolant pump transient is considered as an explanation of the partial melting of the plenum assembly. The primary system pressure response is used to calculate the energy transferred from the reactor core to the coolant and the steam generation rate during the pump transient. The steam generation rate is then used to calculate the heating of the plenum assembly. An energy balance indicates that exothermic oxidation of Zircaloy by steam must have taken place. In calculations of plenum assembly heating, the thermal emissivity of steam is reduced to simulate the effect of hydrogen generated during the oxidation process. It is determined from the calculations that in the presence of an appreciable amount of hydrogen (∼60%), only the thin structures at the lower end of the plenum assembly would have melted, while the relatively thick structures would have been partially ablated. These results are consistent with the observed damage.
