Dounreay milestone reached with concrete 'mega pour'

Work on Dounreay’s newest radioactive waste store grew at the end of December 2020 with the completion of a ‘mega’ concrete pour.

The first floor slab in the new radioactive waste store is now complete. The construction project re-started on 22 June 2020, following the easing of lock down restrictions. Since then, 1,500 t of concrete has been poured and the building walls are above the first floor level.

Dounreay Project Manager Dave Busby said that casting the CMB floor slab was a significant construction milestone as it will allow the team to install the 170 tonne CMB shield door early this year.

Dounreay is Scotland’s largest nuclear decommissioning project and is widely recognised as one of Europe’s most complex nuclear closure programmes.
