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 next generation of liquid-metal fast breeder reactors will likely be passively safe designs in that the reactors will be able to survive a loss-of-flow transient without relying on active safety devices. Thermal distortion of the core assemblies is envisioned as one of the most important contributors to the passive negative reactivity feedback required to control the reactor. Development of these reactors requires that the shape of the distorted fuel assemblies be accurately predicted. It is common practice to use beam elements in the modeling of thermally distorted fuel assemblies. However, by using higher order finite element analysis, it is found that the accuracy of such beam element models are unsatisfactory and should only be used with caution. The investigation shows that this lack of accuracy can be largely overcome by a modification of the beam elements such that the moments created by the frictional contact forces are taken under consideration. In addition, investigation of the effect of the fuel pin bundle indicates that the thermal distortion of fuel assemblies can be made significantly more accurate by including the commonly neglected fuel pins.
