NRC approves Holtec’s Oyster Creek license termination plan as company eyes Gulf South reactor deployments with Entergy and Hyundai

In the span of a single week, Holtec made two announcements that capture the dual nature of the nuclear industry right now. The Nuclear Regulatory Commission approved the company’s license termination plan for Oyster Creek nuclear power plant—a milestone in the site’s decommissioning—while Holtec separately announced a partnership with Entergy and Hyundai Engineering and Construction to explore new reactor deployments across the Gulf South region.

NRC approves the Oyster Creek license termination plan

The NRC’s approval of Holtec’s license termination plan for Oyster Creek is a significant regulatory checkpoint. It doesn’t get much public attention, but it carries real weight in the decommissioning world.

A license termination plan, or LTP, is the formal document laying out exactly how a decommissioning company will prove a site is clean enough for unrestricted release. Getting it approved means the NRC has accepted the roadmap. The work isn’t done—but the plan to finish it has cleared a major hurdle.

The company formed a partnership with Entergy and Hyundai Engineering and Construction to evaluate potential sites for new reactor deployments across the Gulf South.

Oyster Creek sits in Lacey Township, New Jersey, and holds a notable place in US nuclear history as one of the oldest commercial nuclear power plants in the country, having first come online in 1969. The plant stopped generating power in 2018. Holtec took over ownership shortly after to manage its decommissioning.

Why the LTP approval matters for the timeline

Holtec didn’t acquire Oyster Creek by accident. The company has built a business model around accelerating decommissioning—taking plants that utilities might have left in long-term SAFSTOR status for decades and pushing them toward active decontamination and demolition, known as DECON, much faster.

Traditional SAFSTOR could leave a site dormant for up to 60 years, waiting for radioactivity to decay before cleanup begins. Holtec’s approach compresses that timeline significantly, which matters for cost management and for communities that want to know what happens to the land.

With the LTP approved, the next steps involve completing the actual site cleanup in accordance with that plan, then demonstrating to the NRC that the site meets release criteria. Once those standards are confirmed, the NRC can formally terminate the license—at which point the land is no longer regulated as a nuclear facility and can potentially be repurposed. For a coastal New Jersey community, that’s not a small thing.

Holtec, Entergy, and Hyundai E&C to assess Gulf South reactor sites

While the Oyster Creek news was moving through regulatory circles, Holtec announced something pointing in the opposite direction: new nuclear, not old.

The company formed a partnership with Entergy and Hyundai Engineering and Construction to evaluate potential sites for new reactor deployments across the Gulf South. Each partner brings something distinct. Holtec is the reactor developer, working on its SMR-300 small modular reactor design. Entergy is a major regional utility with a transmission network spanning Louisiana, Mississippi, Arkansas, and Texas. Hyundai E&C is the construction partner, with experience in large-scale energy infrastructure.

The evaluation is expected to cover site suitability, grid integration needs, and the regulatory pathway required to bring new reactors online. Entergy’s existing grid runs through states with significant industrial load and growing energy demand—both factors that make the economics of new nuclear worth examining seriously. The Gulf South, in that context, is a logical geographic focus.

This isn’t a construction announcement. It’s a feasibility and evaluation partnership, meaning the partners are still in the early stages of figuring out whether specific sites make sense. A utility the size of Entergy putting its name on this kind of evaluation, though, reflects a broader shift in how regional power companies are thinking about their long-term generation mix.

Holtec’s dual role in a changing nuclear landscape

What makes Holtec’s position unusual is that it’s operating on both ends of the nuclear life cycle simultaneously. On one side, it’s managing the cleanup of legacy plants that have reached the end of their operational lives. On the other, it’s developing new reactor technology aimed at the next generation of nuclear deployment.

Holtec’s SMR-300 is currently moving through the NRC’s regulatory review process. Small modular reactors have attracted significant federal policy support in recent years, with the US government backing advanced nuclear development through funding programs and streamlined licensing efforts. That policy tailwind gives developers like Holtec more runway to pursue partnerships and site evaluations.

Entergy already operates nuclear plants in the Gulf South, so the region isn’t unfamiliar territory. What’s changed is the scale of ambition. SMRs are designed to be more flexible and potentially cheaper to build than large conventional reactors, which makes them candidates for deployment in areas where a full-scale plant wouldn’t be economically viable—a meaningful distinction for a region with widely distributed industrial load.

The two Holtec International announcements this week—one closing a chapter on a 1960s-era plant, the other opening a conversation about future reactors—reflect where the US nuclear industry sits right now. Decommissioning the old and planning the new are happening in parallel, sometimes within the same company. The NRC’s approval of the Oyster Creek LTP moves one legacy site closer to a clean closure, while the Gulf South partnership with Entergy and Hyundai E&C signals that Holtec is already focused on what comes next.
