Our team

Rory O’Sullivan is the Chief Executive Officer at Moltex. He joined the company as Chief Operating Officer in the UK in 2015, before moving to Canada in 2018 to expand its operations into North America. Under his leadership, the company has not only made innovative technological advances, but also secured government funding and essential support from industry as well as community and Indigenous groups. By attracting the right talent and partnerships, he has re-tooled Moltex to move from concept design to engineering design of its flagship reactor, with the goal of commercial operations in New Brunswick, and expanded rollout soon after. Rory began his career as a project manager at the Bouygues group, garnering awards for construction projects in London and for building housing capacity in Haiti. With a vision for delivering clean, low-cost energy to the world, he co-founded Energy Process Developments Ltd to pursue advanced nuclear power generation and led a government-funded feasibility study on the development of a prototype molten salt reactor. Rory sat on the International Atomic Energy Agency’s advisory committee on molten salt reactors and was a Forbes 30 Under 30 Standout. He obtained 1st-class honours in Mechanical and Manufacturing Engineering from Trinity College Dublin and a degree in Mechanical Design Engineering from the Institut National des Sciences Appliquées de Lyon in France.
