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.

Core-melt accidents as modeled in risk studies result in severe consequences to the environment of a nuclear power plant, only if the containment function of the plant is assumed to fail during the accident. To protect the containment function of a pressurized water reactor with double containment during a coremelt accident against the dominant late failure modes, a relief condenser vent system, if useful or necessary, in combination with an outside spray cooling between the primary steel containment and the secondary concrete containment, is proposed. The outside spray cooling system supports the removal of the decay heat by condensing evaporated sump water at the primary containment shell. Pressure buildup caused by the generated noncondensable gases is effectively limited by the relief condenser vent system located within the primary containment. Thereby, a relatively small flow of the steam-gas mixture in the containment is first guided through a condenser where most of the steam is condensed. The remaining noncondensable gases are then released via a conventional outside filter train in a controlled manner. Safety problems due to hydrogen combustion, which may arise due to the operation of the proposed system, can be prevented by design and operation of the system. By venting, the containment atmosphere is finally inerted.
