Can US revamp shipbuilding sector by turning to nuclear-powered ships?
Nuclear Power's Role in Revitalizing U.S. Shipbuilding
The introduction of advanced small modular reactors (SMRs) in maritime vessels presents a significant opportunity for the U.S. shipbuilding industry. Christopher J. Wiernicki, Chairman and CEO of ABS, emphasizes that this technology could transform the commercial shipping model and enhance national energy security. As the U.S. currently ranks 19th in global commercial shipbuilding, the adoption of SMR technology could serve as a catalyst for revitalization.
Transforming U.S. Shipbuilding with SMR Technology
Wiernicki believes that developing a marinized SMR demonstrator is crucial for the future of U.S. shipbuilding. He describes SMR technology as a “key transformational technology” that will change the economics, operation, and design of vessels. This shift is not only a global narrative but also a domestic one, linking national energy and economic security with the revitalization of U.S. shipbuilding.
The potential economic benefits of SMR technology are compelling. Wiernicki notes that when considering fuel differentials, compliance costs, and residual value, the overall expenses of operating an SMR-powered vessel could be comparable to those of traditional fossil fuel options. However, he stresses that significant work remains to support the adoption of this technology.

To harness the full potential of new nuclear technology, Wiernicki calls for investment and the creation of a “new nuclear playbook.” This playbook should differentiate commercial maritime applications from military and land-based uses. He also highlights the importance of public engagement and education in fostering acceptance of nuclear power in the maritime sector.
Regulatory frameworks will play a critical role in unlocking the potential of SMRs. Current regulations are tailored for large land-based reactors and do not adequately address the unique needs of marine applications. Wiernicki advocates for identifying regulatory gaps and developing a dedicated framework to support SMRs, along with international collaboration on licensing standards.
In light of China’s dominance in the maritime sector, U.S. lawmakers have introduced the “SHIPS for America Act” to enhance the competitiveness of the American commercial maritime industry. With only about 80 U.S.-flagged ships engaged in international commerce compared to over 5,500 Chinese vessels, the urgency for revitalization is clear.
Investing in nuclear power for shipping could position the U.S. to reclaim its status as a maritime superpower. As the industry moves toward sustainability and clean energy sources, nuclear power may play a pivotal role in shaping the future of maritime operations.
