The UK has a significant opportunity to be positioned at the forefront of the global transition from a carbon intensive shipping industry, which is prone to geopolitical risk, to one driven by innovation and emerging technologies such as nuclear energy.

Six businesses have come together to launch the UK Maritime Nuclear Consortium, with the aim of developing a viable pathway for nuclear powered vessels. They are looking to assess regulation, safety, security and the insurability of nuclear merchant vessels, all of which will be essential to make nuclear shipping commercially feasible.

Brief History

Nuclear powered commercial vessels have been tried before. The NS Savannah which launched in 1959 was the world’s first nuclear powered merchant vessel. It proved that nuclear propulsion was possible, but it ultimately failed to take off commercially due to high costs, complexities with crews and limited cargo capacity. There have been very few nuclear-powered merchant vessels to date.

Legal Issues

Nuclear vessels present an array of legal issues:

Ownership

The first, who owns the reactor. Early indications suggest that ownership will mirror the aviation sector, and the nuclear reactor will be leased to the vessel owner. This raises fundamental issues:

• Who will be liable in the event of a nuclear incident
• Who controls operational decisions affecting reactor safety
• How do flag states regulate split ownership

Insurance

Insurance represents another significant challenge. P&I clubs typically exclude nuclear risks due to the potential for catastrophic damage which would go beyond the insurer’s capacity to offer coverage. The NS Savannah had indemnities provided by the US Government so it could operate and there are questions today whether the private sector alone can provide adequate insurance against nuclear risk or if government intervention is required.

Regulatory gaps and public confidence

Current regulatory frameworks are not yet well equipped to deal with nuclear powered commercial vessels. Additionally, public concerns about nuclear safety continue to influence policymakers.

Practical Considerations

There are also numerous practical considerations that have legal significance. Plans need to be made to show how to salvage reactors should a vessel sink. There is a security risk posed by potential terrorists getting hold of reactors. There are also concerns whether all ports will allow access for nuclear powered vessels.

Why Legal Expertise Matters

What is evident is that the pace of innovation in the maritime sector is accelerating. Nuclear propulsion may be transformative, but only with the right legal and regulatory frameworks in place. Engaging lawyers early is vital to ensure compliance with new regulatory regimes, often spanning borders. Lawyers can play a key role in allowing stakeholders to effectively address complex insurance and liability challenges.
