It’s in our heritage

The history of International Nuclear Services is closely interconnected with the development of civil nuclear power in the UK – a story that stretches back to the 1940s.

INS began life over 40 years ago as the Spent Fuel Services and Transport Division of British Nuclear Fuels (BNFL) who at the time were responsible for providing services that covered almost every part of the nuclear fuel cycle, including reprocessing and spent fuel management.

In 2008 INS became a wholly owned subsidiary of the Nuclear Decommissioning Authority (NDA), an executive non-departmental public body responsible for ensuring the safe and efficient clean-up of the UK’s nuclear legacy.

INS contributes to delivering the NDA’s strategy by providing specialist nuclear transport, design and licensing services, and by managing NDA’s inherited fuel cycle contracts with UK and overseas customers.

A big part of our work in support of NDA’s strategy involves the transportation of spent fuels and the return of waste to countries of origin. We operate Pacific Nuclear Transport Limited (PNTL), the world’s most experienced nuclear shipping company who have a fleet of three INF3 nuclear transport carriers.

As well as continuing to contribute to the delivery of NDA’s strategy we use the skills and experience we have accumulated over 40 years to help a range of customers unlock their own nuclear challenges.

People choose International Nuclear Services because our world-leading experience inspires trust. Without it we wouldn’t be able to keep delivering safely and securely for our customers, time after time.
