These days, the ship of civil nuclear technology we are all aboard is sailing through a turbulent passage. The winds and currents are favorable, but there are swells ahead: steep energy-demand projections, buoyant equity valuations, splashy announcements, a generational realignment of nuclear policies and institutional norms.
Part of the reason we chose “Building the Nuclear Century” as the theme for this year’s Winter Conference was to put some ballast in the hull of the nuclear conversation.
Advanced nuclear fission and fusion energy development are accelerating, both here and around the world. And yet, at least in the U.S., we are still years away from connecting commercial Gen IV systems to our grid.
In a world growing increasingly impatient, how do we stay on task and deliver? There are three ingredients to success.

In the present study, the effect of Hf and Ti substitution of Zr in the ZrCo alloy, used for hydrogen isotope storage, has been investigated in order to ascertain the improvement of the anti-disproportionation property of ZrCo hydrides. The ultimate goal of the investigation is to develop a safe and economically viable solution for the long-term storage of deuterium and tritium. The intermetallic compounds Zrl-xTixCo and Zrl-xHfxCo (x = 0.1, 0.2) were prepared and their suitability for hydrogen isotope storage, protium (H) and deuterium (D), was investigated. The alloys were synthesized by arc melting under a controlled argon atmosphere and characterized by scanning electron microscope and X-ray diffraction analysis. The hydrogen isotope storage behavior of these alloys was probed by loading and unloading protium and deuterium. We present the pressure, composition, and temperature measurements for desorption, together with the thermodynamic parameters (enthalpy and entropy) of these alloys. The experimental results show that Ti and Hf substitution in the ZrCo alloys is suitable for fast delivery of hydrogen isotopes, even after their long-term storage.
