New films focus on waste shaft

Two new films have been released about an underground shaft used for the disposal of intermediate level waste at Dounreay more than 30 years ago.

Decommissioning the 65-metre deep, vertical shaft is one of the biggest engineering and environmental tasks in the site closure programme.

Hydraulic isolation of the Dounreay shaft is a seven-minute film about the successful first phase of its decommissioning.

This involved installing a grout barrier in the rock around the shaft to reduce the amount of groundwater that can get into the shaft when work begins to empty it.

History of the Dounreay shaft is a three-minute film that charts the construction of the shaft and the disposal of waste from the late 1950s until an explosion in 1977.

Both films can be viewed in the video library of dounreay.com and on YouTube
