# Is the Port of Corpus Christi Becoming the US Hub for Maritime Nuclear?

The Port of Corpus Christi — the USA's largest port for petroleum exports — has signed two separate agreements to explore nuclear maritime technologies: one memorandum of cooperation with the US Department of Transportation's Maritime Administration (MARAD), and one memorandum of collaboration with UK-based maritime nuclear specialist Core Power. The dual signings, reported August 20, make Corpus Christi the second US seaport to formalise ties with MARAD on nuclear propulsion, following the Port of Long Beach in California, which signed a comparable agreement last month. Core Power's study scope explicitly covers both floating nuclear power plants (FNPPs) and port readiness for nuclear-powered commercial vessels — two distinct deployment pathways that share overlapping regulatory and infrastructure requirements.

This is not a construction commitment. Neither agreement selects a reactor technology or vendor, initiates licensing, commits capital, or authorises deployment. What it does do is establish a structured fact-finding framework at a port that handles significant energy commodity flows, giving the maritime nuclear sector its first real-world Gulf Coast reference environment.

## MARAD's SMR Maritime Initiative: Where Corpus Christi Fits

MARAD launched its SMR maritime initiative in May, issuing a Request for Information aimed at developing an SMR model that the agency says could revitalise US shipbuilding, reduce shipping costs, and advance what the administration frames as energy and maritime dominance objectives. The initiative is explicitly linked to President Trump's executive orders on energy and maritime policy.

The memorandum between MARAD and the Port of Corpus Christi covers a broad scope: potential integration of [SMR](https://smrintel.com/glossary/baseload) technologies into port energy systems, resilient port microgrids, shoreside power architecture, infrastructure capable of supporting emerging vessel propulsion concepts, and workforce development. Maritime Administrator Stephen Carmel highlighted the Gulf Coast supply chain resilience angle specifically, citing extreme weather and grid disruption scenarios as drivers for firm, reliable port power.

The Long Beach agreement last month was the first such partnership. Corpus Christi is the second. The pace — two major US ports signing within roughly a month — suggests MARAD is moving to build a coalition of port stakeholders before the technical and regulatory frameworks are fully defined, a common federal strategy to generate industry buy-in early in a programme's lifecycle.

## Core Power's Site-Specific Study: Two Pathways, One Port

The more technically detailed of the two agreements is the Corpus Christi memorandum with Core Power. The UK-based company, which focuses on maritime nuclear energy, will conduct what it describes as a site-specific maritime nuclear readiness study. Core Power's rendering referenced in the source depicts a 300 MWe FNPP — the specific rating cited in the source material — though the study itself does not commit to that design.

The study will assess two distinct but related pathways:

**Floating Nuclear Power Plants (FNPPs):** The assessment will cover site-specific technical, environmental, regulatory, operational, and commercial requirements. Work will examine marine and site conditions, water use and discharge, grid connection, potential customer and offtake requirements, candidate locations and mooring, safety and security, permitting, operations, maintenance, and long-term service support.

**Nuclear-Powered Commercial Ship Calls:** Separately, the study will examine what Corpus Christi would need to safely and routinely receive nuclear-powered commercial vessels. That scope includes a reference vessel and power-system envelope, transit and berthing procedures, port-stay safety and security, cargo interfaces, emergency preparedness, liability frameworks, classification society requirements, and the roles of both US and international maritime and nuclear authorities.

Core Power CEO Mikal Bøe was quoted directly: "For floating nuclear power plants, we need to understand sites, grids, customers, operating models and long-term service arrangements. For nuclear-powered commercial ships, we need safe and predictable pathways for transit, berthing and routine port operations."

The framing is deliberately incremental. Core Power characterised the work as "a preliminary, fact-finding exercise" — language that manages regulatory and political risk while still generating the site data the company needs to advance [first-of-a-kind (FOAK)](https://smrintel.com/glossary/foak) deployment planning.

## What This Means for the Broader Maritime Nuclear Sector

The Corpus Christi dual-agreement structure is notable for several reasons beyond the press release.

**Gulf Coast geography matters.** Unlike Long Beach, which is a container port serving trans-Pacific trade, Corpus Christi is the USA's primary petroleum export gateway. A port that already handles large energy commodity flows — and the regulatory, security, and logistics infrastructure that entails — presents a different risk profile for nuclear integration than a pure container terminal. The existing energy-industry workforce and regulatory familiarity with hazardous materials are genuine starting assets for a maritime nuclear programme.

**The FNPP pathway faces a long regulatory runway.** No FNPP has been licensed and operated commercially by a Western regulatory framework. Russia's *Akademik Lomonosov* provides the only operational precedent, and it was built and regulated entirely within Rosatom's domestic framework. For Core Power's study to translate into deployment, it will need to navigate NRC jurisdiction for the nuclear installation, US Coast Guard authority for maritime operations, and potentially IMO frameworks for international ship calls — a multi-agency regulatory challenge that has not been resolved anywhere in the Western world.

**The workforce development angle is underappreciated.** Both agreements reference workforce training. Corpus Christi's proximity to Texas A&M University's maritime programmes and the existing Gulf Coast energy industry talent base could make it a credible location for developing the nuclear-qualified mariners and port technicians any commercial maritime nuclear programme will eventually require.

**Two ports do not make a market.** Long Beach and Corpus Christi represent different cargo profiles, geographies, and energy needs. The sector needs to watch whether MARAD converts these MOUs into funded demonstration programmes with defined technical milestones — or whether the agreements remain political signalling without capital commitments. The RFI issued in May has not yet produced publicly announced results.

## Key Takeaways

- The Port of Corpus Christi — the USA's largest petroleum export port — has signed memoranda with both MARAD and Core Power to explore maritime nuclear technologies.
- It is the second US seaport to formalise a MARAD partnership on nuclear propulsion, after the Port of Long Beach signed last month.
- Core Power's site-specific study covers two pathways: floating nuclear power plants (FNPPs, with a 300 MWe reference design noted in source imagery) and port readiness for nuclear-powered commercial ship calls.
- Neither agreement commits to a specific reactor technology, vendor, capital investment, or licensing action.
- MARAD launched its SMR maritime initiative in May with a Request for Information; no publicly announced results from that RFI have been reported.
- Regulatory complexity — spanning NRC, US Coast Guard, and potentially IMO — remains the critical long-term constraint on any FNPP or nuclear ship deployment in US waters.

## Frequently Asked Questions

**What did the Port of Corpus Christi sign regarding nuclear energy?**
The port signed two separate agreements: a memorandum of cooperation with MARAD to explore SMR integration, port microgrids, and nuclear-capable vessel infrastructure; and a memorandum of collaboration with Core Power to conduct a site-specific study of floating nuclear power plants and nuclear-powered ship port calls.

**What is MARAD's role in maritime SMR development?**
MARAD — the US Department of Transportation's Maritime Administration — launched an SMR maritime initiative in May, issuing a Request for Information to gather industry input on developing SMR-powered commercial shipping. It has since signed port partnership agreements with Long Beach and Corpus Christi as early engagement steps.

**What is Core Power's 300 MWe FNPP?**
Core Power is a UK-based maritime nuclear energy specialist. Its reference FNPP design, depicted in renderings associated with the Corpus Christi announcement, is rated at 300 MWe. The Corpus Christi study does not commit to this or any other specific design — it is a fact-finding exercise to assess site requirements.

**Does this mean nuclear reactors will be built at Corpus Christi?**
No. Both agreements are explicitly preliminary. They do not select a reactor technology, initiate NRC licensing or permitting, commit investment, approve construction, or authorise deployment of an FNPP or nuclear ship calls. The work is scoped as evidence gathering.

**What regulatory bodies would oversee maritime nuclear deployment in the US?**
A US maritime nuclear deployment would likely require coordination between the Nuclear Regulatory Commission (for the reactor system), the US Coast Guard (for maritime safety), and potentially the International Maritime Organization for internationally trading nuclear-powered vessels. No unified Western regulatory pathway for commercial FNPPs currently exists.
