South Carolina public utility Santee Cooper and its partner South Carolina Electric & Gas (SCE&G) called a halt to the Summer-2 and -3 AP1000 construction project in July 2017, citing costly delays and the bankruptcy of Westinghouse. The well-chronicled legal fallout included indictments and settlements, and ultimately left Santee Cooper with the ownership of nonnuclear assets at the construction site in Jenkinsville, S.C.

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?

CFPP LLC, the limited liability company established by Utah Associated Municipal Power Systems (UAMPS) in 2020 to bring its Carbon Free Power Project to fruition, has applied to the Nuclear Regulatory Commission for a limited work authorization (LWA) to permit certain early project construction activities prior to the issuance of a combined license (COL). In a July 31 news release, CFPP said that should its application be approved, early-scope construction on the small modular reactor project would likely begin in mid-2025.

Oklo's 1.5-MWe fast spectrum design known as Aurora is the first advanced non–light-water reactor to be accepted for a licensing review by the Nuclear Regulatory Commission. Both the reactor’s design and the anticipated licensing process mark a major departure from large light-water reactor design and licensing.
