The story
INS began as the Spent Fuel Services division of British Nuclear Fuels (BNFL). As part of the restructuring of BNFL, 49% of the business was transferred to the NDA in 2006. It was renamed International Nuclear Services in 2007 and in April 2008, as BNFL was wound up, the NDA acquired the remaining 51% of INS.
