Lloyd’s Register (LR) is working with Deployable Energy, a Houston, TX based nuclear technology company, to advance the safe use of micro-nuclear reactor technology to power ships.
LR Advisory has been guiding the development of Deployable Energy’s Unity Nuclear Battery, a compact, factory-built micro-reactor designed to deliver safe, zero-emission power, for a wide range of applications. By replacing traditional marine fuels, the technology has the potential to reduce emissions, increase vessel efficiency and extend time at sea without refuelling.
A recent technical workshop led by LR brought together experts from across its classification, safety assurance and advisory teams to assess the steps needed to align Unity with international safety standards and regulatory expectations. The discussions focused on the critical safety case and licensing requirements that will underpin regulatory approval for nuclear propulsion on vessels.
Early collaboration with LR ensures that safety, integration and regulatory challenges are addressed from the outset.
