- NRS Ltd. is responsible for the safe and compliant decommissioning of Trawsfynydd Nuclear Power Station in Gwynedd, North Wales. Built in the early 1960’s, the Site ceased generating electricity in 1991 and has been undertaking decommissioning works since. <br/>The next phase of the decommissioning programme will principally feature modification of the two former civil nuclear Reactor Buildings which, in current state, offer safe and secure storage of housed plant. The project will involve the systematic deconstruction and partial demolition of each Reactor Building, delivering a reduced height configuration compliant with existing planning commitments and lessening the visual impact on the landscape. In addition, a package of civil new build and remedial works will be delivered to prolong the durability of the retained structures and reduce disproportionate asset management liability. The end product will offer compliant protection of the stored inventory, ready for successor phases of decommissioning activity on the Site.Value not stated
