Tokio Marine GX backs new insurance for nuclear fusion risks

The initiative aims to ensure insurance frameworks and capacity are in place.

Tokio Marine GX (TMGX) and specialist MGA Northcourt, part of the Optio Group, have launched NC Fusion, the first insurance facility in the Lloyd’s market dedicated to nuclear fusion technology. 

The initiative aims to ensure insurance frameworks and capacity are in place to support the development and eventual commercial rollout of fusion energy.

The new facility fills a gap in the insurance market. Traditional nuclear insurance products were designed for fission technology, which involves very different risks and includes radiation exclusions. 

Fusion, by contrast, produces no long-lived radioactive waste, cannot melt down, and presents a distinct risk profile that requires tailored insurance coverage.

NC Fusion will provide coverage across all stages of fusion development — from research and testing to commercial energy generation. Its structure allows insurance capacity and coverage to grow in step with technological maturity.
