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.

Seamless hot extruded tubes serve as structural materials of high-temperature gas-cooled reactors and coal conversion systems with exposure temperatures up to 1000°C. The tube dimensions (∼130- × 15-mm diam) were produced according to the proposed requirements for methane reformer heat exchangers of nuclear process gas production systems. The most sensitive extrusion parameter is the temperature of the expanded billet at the press, where it should reach 1140 to 1180°C depending on the materials investigated: Incoloy-800H, Incoloy-802, Hastelloy-X, Inconel-617, and Nimonic-86. To qualify the extrusion products, the mechanical properties obtained from tensile tests at room temperature and temperatures up to 1000°C are compared for tube products. Strengthening effects at 800°C are explained by carbide precipitation during the test, especially of alloys 800H and 802.
