IT services provider Computer Sciences Corp has won a renewal of its IT outsourcing deal with British Nuclear Group worth $135m.

The El Segundo, California-based company first signed an outsourcing deal with the nuclear site management company in 2000 when it acquired its IT division IT Services Ltd in an $87m five-year deal.

The new contract is also for five years and covers helpdesk, applications support, networks, managed security and desktop services for 12,000 users.
