The government has kicked off a multi-billion pound programme of handing over nuclear sites to the private sector with offers to bid for the Drigg low-level waste repository. The Nuclear Decommissioning Authority has asked companies to fill in a pre-qualification questionnaire which will determine whether they are eligible to make a formal offer to manage the facility in Cumbria. British engineer Amec and US project manager Washington are among those likely to bid. The NDA is expected to choose a private sector operator for what used to be a top-secret location by October next year.
