Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The effect of cyclotron-implanted helium on the fatigue behavior of the molybdenum-base alloy TZM was investigated at 900°C. The results show that the helium-implanted TZM alloy fatigue specimens exhibit almost double the fatigue life of the unimplanted fatigue specimens. Optical and transmission electron microscope examination of specimen sections adjacent to the fracture revealed no evidence of significant differences between the helium-implanted and unimplanted specimens. However, transmission electron microscope examination of helium-implanted fatigue specimen sections annealed at 1310°C (0.55 Tm), following testing, revealed the presence of cavities within the grain matrix as well as cavities associated with dislocations. By comparison, the unimplanted specimens exhibited a structure characteristic of a well-annealed material. Based on the results of this study and on other available experimental evidence, it was concluded that the enhanced fatigue life of helium-implanted TZM alloy at 900°C resulted from the presence of substitutional helium-defect clusters, possibly associated with dislocations and/or precipitates. However, additional experiments will be necessary to firmly establish the details of the strengthening mechanism indicated by the present results.
