French nuclear group Areva, which incurred massive losses last year, announced yesterday it would cut up to 6,000 jobs worldwide as it seeks to slash 1 billion euros from its costs by 2017. The number of job cuts will be between 5,000 and 6,000 worldwide, said the group's human resources director. Between 3,000 and 4,000 of the job losses will be in France. Areva had earlier said it plans to reduce its labor costs by around 15 percent in France and 18 percent internationally. The group currently employs around 45,000 people, including some 30,000 in France.
