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.

Work has been performed to develop a Three Mile Island Unit 2 (TMI-2) simulation model for MELPROG/TRAC capable of predicting the observed plant behavior that occurred during the accident of March 1979. A description of the TMI-2 plant model is presented, and calculation results through 174 min of the accident are discussed. Using the boundary conditions recommended for the TMI-2 Analysis Exercise, the calculation predicts pressurizer draining and core recovering prior to fuel rod damage. A parametric calculation (with reduced makeup flow) was also performed and is in better agreement with the observed plant behavior. Efforts are under way to proceed with an accurate simulation through phases 3 and 4 of the accident (174 to 227 min and 227 to 300 min, respectively).
