Established in 1986 as NIRA Limited on the Isle of Man, the organisation’s original mission was to provide machinery breakdown reinsurance for EMANI members in the nuclear sector.
As the industry evolved, so did NIRA broadening its expertise and strengthening cooperation with international insurers and energy operators.
In 2008, the association was restructured as a mutual reinsurance organisation in Luxembourg, marking a defining step forward.
This transition brought NIRA under EU jurisdiction, reinforcing its governance framework and enabling broader engagement with the global energy and nuclear insurance markets.
Over the years, NIRA has developed into a trusted and specialised leader in the field of reinsurance for energy and nuclear risks.
Its growth has been driven by a combination of technical expertise, disciplined underwriting, and member collaboration.
Today, NIRA continues to support its international members and partners with tailored solutions, sustainable capacity, and a commitment to excellence ensuring resilience in one of the world’s most critical industries.
