Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

Be-copper alloy duplex structures are planed to be used as the structural material of the first wall for ITER. CuCr1Zr0.1 copper alloy is one of the prospective components of such structures. To ensure safety and to solve ecological problems concerning fusion reactor operation it is necessary to have estimations of tritium inventory in the copper alloy CuCr1Zr0.1 and in Be-copper alloy duplex structures.
In this work the results of the following experiments on determination of hydrogen permeation parameters are presented:
• Investigation of hydrogen permeation for beryllium-copper duplex structure. Experiments were carried out in the temperature range from 873 K to 1023 K, at input hydrogen pressures between 102 Pa and 103 Pa.
• Investigation of hydrogen permeation for copper alloy CuCr1Zr0.1 in the temperature range from 723 K to 973 K, at input pressures of hydrogen between 102 and 103 Pa and for samples with different thickness.
