Sellafield is a large and complex nuclear chemical facility located in West Cumbria. The site has played a pivotal role within the nuclear industry since the 1940s. Site operations include fuel reprocessing, fuel fabrication and storage of nuclear materials and radioactive wastes.
Calder Hall, located on the site, was the world's first commercial nuclear power station. Generation started in 1956 and ceased in 2003.
Windscale, also located on the site, comprises three reactors. Two of the reactors were shut down in 1957 and the third one was closed in 1981. Substantial damage by fire to one of the reactors in 1957 has created significant additional decommissioning challenges.
Overview
| Age | Operated since 1947 |
|---|---|
| Site Stakeholder Group | West Cumbria Site Stakeholder Group (WCSSG) |
| Site Licensee | Sellafield Limited |
| Parent Body Organisation | Nuclear Management Partners (NMP) Ltd |
| Status | Defuelling and Partial Decommissioning |
| Cost - Lifetime (total discounted nuclear liability) |
£32,066m |
* The costs of discharging the nuclear liability will be incurred over a significant period of time. To take account of the time value of money, the costs are "discounted" back to a present value. Effectively this is the amount that would need to be invested today, at a set rate of interest (the discount rate) in order to pay for the liability in the future as it falls due.

Site Restoration
| Target | Status | Commentary |
|---|---|---|
Continue programme of asset improvements to manage ageing infrastructure of plant and buildings |
On target |
On track |
Ongoing decommissioning and demolition of redundant facilities, specifically: Progress critical path activities to deliver the replacement Separation Area Ventilation stack, which will enable the demolition of the First Generation Reprocessing plant venticlation stack |
On target |
On track |
Progress critical path activities to the start of retrievals for legacy wastes, specifically: First Generation Magnox Storage Pond - completion of new skip handler tooling and completion of integration works testing |
Behind target |
NDA set a stretch target for 2011/12, completion to this date will not be met but completion is still in line with base date in 2012/13. |
Progress critical path activities to the start of retrievals for legacy wastes, specifically: Magnox Swarf Storage Silos - complete the construction of Retrievals Machine 2 and start factory acceptance testing |
Behind target |
Will be delivered within the year but this will be later than the date originally expected by the NDA.
|
Progress critical path activities to the start of retrievals for legacy wastes, specifically: * Magnox Swarf Storage Silos - progress the design for the waste encapsulation and waste product transfer capability |

On track |
Progress critical path activities to the start of retrievals for legacy wastes, specifically: Pile Fuel Cladding Silo - commence stage 2 construction of the 'Superstructure' and control room |
Behind target |
NDA set a stretch target for 2011/12, completion to this date will not be met but completion is still in line with base date in 2012/13.
|
Progress critical path activities to the start of retrievals for legacy wastes, specifically: Pile Fuel Storage Pond - progress active commissioning of the local sludge treatment plant storage tanks |
The project has completed Inactive commissioning and is on programme to demobilise by the end of the FY. However reduced sludge arisings from retrievals to date mean that an early commitment of the facility to active operations is not required. Alternative strategies are being considered.
