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?

This paper assesses the structural dynamics of the deck structure and the resulting loading on the deck supports of a pool-type liquid-metal fast breeder reactor during a hypothetical core disruptive accident. During this hypothetical accident. the sodium above the core is considered to be propelled upward until it impacts against the deck structure. This hydrodynamic loading could produce structural damage and sodium leak paths. The deck is a three-dimensional composite structure of beams, plates, and concrete fill. It is supported at its outer periphery by the surrounding concrete foundation. The deck provides top closure of the main tank and support for the intermediate heat exchangers, primary pumps, rotating plugs, and primary and secondary tanks. A finite element model is used to study the deck dynamics during slug impact. The structural stiffening effect of the concrete fill is assessed, and results are given for deck displacement and velocity histories and deck support column reaction forces.
