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 possibility of instabilities under certain conditions of operation has been a special concern for boiling water reactors (BWRs). A stability analysis is performed to demonstrate that the total system and its primary components are inherently stable over the allowable operating envelope. The current methodology used by BWR fuel vendors for core reactivity and channel hydrodynamic stability is based on frequency domain analysis. RETRAN is the Electric Power Research Institute time domain system transient analysis code that is widely used by domestic and foreign utilities. RETRAN allows the reactor system to be modeled in a highly accurate manner including all important phenomena (linear and nonlinear) associated with anticipated and unforeseen conditions of operation. RETRAN is demonstrated to be adequate for the analysis of total plant stability, core reactivity stability, and channel hydrodynamic stability. All key phenomena are adequately modeled by RETRAN and core reactivity analyses have been shown to agree well with measured plant data.
