The huge package of work over the next five years will be spread across 10 sites in the UK and be handled by Magnox South and Magnox North, put in control of the decommissioning projects.

The framework is being broken up into three distinct packages. The first will cover demolition of radioactive structures and removal of plant, the second covers demolition of inert structures and the third specialist removal of asbestos.

Magnox said it may extend the framework by an extra three years taking the expected demolition packages spend to £286m and asbestos removal to cost £78m.
