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.

In nuclear power plants, instrument failures must be detected and compensated for before a significant decrease in plant performance occurs. The improved generalized likelihood ratio method to detect and identify a failure and a control algorithm in the event of an instrument failure is developed. The failure detection algorithm and the control algorithm are combined and applied to a pressurized water reactor pressurizer. Computer simulation tests show that on-line prompt failure detection and compensation through control action can be performed very successfully even when there is an instrument failure.
