Another first for Capenhurst
Capenhurst is the first UK nuclear site to use rope access instead of scaffolding to access areas that cannot be reached by scaffolding or scissor lifts.
Last week, hanging 25 meters above drums of depleted uranium and uranium hexafluoride, contractors APC begun to install a new smoke detection system in the site's former diffusion plant, which is now used as a uranic storage area.
Ian Mason, Head of Uranic Storage at Capenhurst, said: “Both restrictions on physical access for mechanical means, as well as dose rates implications for scaffolders, made it impossible for these methods to be used to access the roof of the building, which meant we had to be innovative in terms of finding a fast and cost-effective method of installing this new system.
“Through the tender process, we challenged our main contractor, Techserve, to find the most suitable rope access team to do the work. Consequently, we have five expert rock climbers and mountaineers, who have an excellent pedigree in commercial work, to provide a unique solution to a complex problem - in fact they're so fast and nimble that it’s proving to be quicker than conventional methods.”
The detection system will be fitted to the entire building and annexes over a period of four weeks. This forms part of preparations for the potential reuse of substantial areas of storage space following the launch of the site's new vision to maximise its assets and grow its business.
Phil Malem, Sellafield Ltd's Head of Site at Capenhurst, said: “Finding new ways of working, such as using rope access instead of scaffolding, is essential for the successful future of this site.
“Not only is rope access incredibly safe, as we approach the end of decommissioning, this project is helping prepare the ground - or the roof - for us to find new ways of using the land assets and operational experience that we have gained from being the first site to complete our clean-up programme.
“Much of our site is a blank canvas of flexible space, coupled with hugely knowledgeable employees and we're currently exploring options of how to change our Lifetime Plan away from remaining a safe storage site to contributing more positively to the NDA's hazard reduction strategy.”
