Reboot: Nuclear needs a success . . . anywhere
The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.
Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?
As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?

In continuation of 20 yr of experience with high-temperature gas-cooled reactor graphite fuel element fabrication (molded fuel spheres and monolithic block fuel elements), NUKEM introduced a new graphite-based material with an inorganic binder produced by molding. A mixture of nickel and sulfur is used as the inorganic binder for natural graphite powder. The fabrication is facilitated by the low temperature of 500°C in generating a chemically and thermally stable nickel sulfide. The newly developed material is suitable as a matrix for the fixation of high-active waste and as a corrosion-resistant layer of the steel supporting tube for final disposal of spent fuel elements. The material of natural graphite/nickel sulfide is distinguished by high density, high corrosion resistance, a low leaching rate, good thermal conductivity, an appropriate coefficient of thermal expansion, and high thermal stability due to the high melting point of nickel sulfide ( 790°C). Currently, a pilot plant for fabrication of containers for spent fuel elements is being erected. Additionally, development work is in progress to obtain basic design data for a high-level waste fixation facility.
