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.

Computerized tomography (CT) has been demonstrated to be a good technique for measuring point density (void fraction) in two-phase flow systems. Recently, improvements have been suggested regarding the choice of filter functions in CT methods. These methods are essentially based on the discrete implementation of the radon inversion formulas that are widely used in the medical imaging area. Such methods do not require any a priori information regarding the distribution of the density (or the void fraction). A very simple method involving the tomographic chord-segment inversion has been developed and tested for two-phase flows having radially symmetric density distributions. This method is much simpler and consumes less CPU time than more general methods of tomographic reconstruction. For test functions, the reconstructed density distributions are almost exact. For air/water bubbly flow data, the reconstructed values have a maximum deviation of ±0.03 g/cm3. The range of investigation of the air/water flow data was 0.6 to 0.9 g/cm3, i.e., a void fraction range of 40 to 10%. These results are comparable to the results obtained by the more general methods based on the radon inversion formulas.
