SELLAFIELD bosses say they've hit milestones in two, billion-pound, 'mega' projects at the nuclear site.

Last week a huge concrete slab was laid to form the ground floor of the Product and Residue Store Re-treatment Plant.
A total of 8,374m3 of concrete was used.
And it's been reinforced with 1,230 tonnes of steel.
The building will provide storage for nuclear material and it was completed exactly a year after it was started.
Also workers at the SIXEP Continuity Project site carried out the first concrete  pour during its construction.
The plant is being built alongside Sellafield’s Site Ion Exchange Effluent Plant, or SIXEP .
The site cleans-up liquid effluents before they are discharged into the sea.
Both developments are classed as billion-pound mega projects.
When finished the facilities will be "integral parts of its mission to create a clean and safe environment for future generations".
Martin Chown, chief executive, Sellafield Ltd said: "I had the chance to meet with some of the construction team and see first-hand their commitment to delivering our infrastructure with passion and pride, always with safety at the forefront."
