Tokio Marine GX (TMGX) has introduced NC Fusion, an insurance facility for nuclear fusion technology, in partnership with Northcourt, launched in October 2025. The UK government has allocated over £2.5 billion to fusion over five years, prompting insurers to provide coverage that diverges from traditional nuclear frameworks.
Unlike nuclear fission, fusion's risk profile is distinct, involving tritium with a short waste lifespan and no meltdown risk. Regulatory classifications in both the UK and US now categorize fusion under health and safety legislation, impacting how insurers model risks.
Insurers must engage with clients early in development to assess risks, supply chains, and coverage needs, ensuring that products align with each company's stage in the fusion technology lifecycle. This proactive approach may serve as a model for the insurance of other rapidly evolving technologies.
