Our role and responsibilities
Magnox, soon to be a NDA subsidiary, is the management and operations company responsible for safely managing 12 nuclear sites and one hydroelectric plant in the UK. Magnox are responsible for managing the sites through their lifecycles, overseeing all aspects of defuelling and decommissioning. This involves safely sending all used Magnox fuel to Sellafield for reprocessing.
Once we have completed the defuelling process we begin preparing each site to enter a passive state. During this time the focus is on decommissioning and deplanting buildings and retrieving, treating and processing any waste.
Each site is then left in a passive state, allowing radiation levels to decay naturally over time. During this time the sites will be continuously monitored and planned maintenance and inspection activities will be undertaken.
Final site clearance is the last stage in a site’s lifecycle, which involves dismantling the reactor vessels and dispatching any remaining waste to its final destination. Once this work is complete sites can be released for a new use.
In Magnox, our mission is clear. We have outlined a number of strategic goals which will mark our progress along the route towards safely delivering our sites into care and maintenance (C&M).
Our work is as diverse as it is challenging, ranging from defueling at Wylfa to the introduction of innovative techniques to accelerate decommissioning and clean-up at Bradwell.
In addition we estimate that, through a combination of technical solutions and different ways of working, £1.8 billion has been saved since 2010.
The Magnox mission
We will safely and securely deliver the sites to closure with a workforce:
- Focused on delivering value to our customers and the taxpayer
- Motivated to deliver the site closure programmes
- For whom we will seek to maximise future employment opportunities.
Our work programmes
All of the common decommissioning projects across the Magnox sites have been grouped into Strategic Programmes. Although every site is different, the core challenges are the same, so tackling work consistently helps drive value and innovation.
Nine programmes; Defuelling, Ponds, Plant and Structures, Waste Projects, Waste Operations, Reactors, Asset Management, Care and Maintenance and Site Restoration, have been established to create a one-stop decommissioning service for the sites. Working this way allows us to use innovative techniques and methods as well as providing a sequenced approach to work using the ‘lead and learn’ approach.
The principles of Strategic Programmes are:
- Single points of accountability
- Consistent solutions
- Sites managed in an optimised sequence
- Lead and learn as programme teams move around sites
- More efficient use of resources
- Consolidated supply chain solutions
- Cost-effective, value for money delivery
- Utilisation of specialist skill-sets
