Transcript

  • 1. Bespoke Engineering Solutions Andrea Basso Head of Engineering for Nuclear Engineering Services (NES) 1 Presentation title - edit in the Master slide
  • 2. Why bespoke engineering solutions? Wastes – 1 April 2010 and estimated for future arising volume and masses in UK NDA – The 2010 UK Radioactive Waste Inventory: Main Report 2
  • 3. Nuclear Waste in the UK Majority of the Nuclear wastes in the UK are stored at Sellafield in four main storage facilities. These facilities contain waste such as: irradiated and non-irradiated steel, activated stainless steel, reactive metals, organic / cellulosic material, graphite, cans and drums etc. 3
  • 4. Why we need Bespoke Solutions •We need unique bespoke solutions to retrieve, size reduce and encapsulate waste • Two mechanical rotating, extending arms with and end effector which is able to pick-up a rope and crab in-cell from a crane or other device and manage the deployment of the crab to cover the full silo surface. • The arms are extendable to 4 metre length and designed and manufactured with tolerances at full extension +/- 50mm and +/- 0.1 degree on rotation. • To drive the arms a chain driven system was developed. • SSD could be fully software integrated with the crane or other rope and crab deployment. •NES Solution - Second Stage Deployment (SSD) system
  • 5. NES Solution - Waste levelling Silo Rake • The rake ensures waste is levelled for flat retrieval to avoid loading the civil structure of the silo with forces derived from the collapsing of unlevelled waste. • Silo rake fits inside a standard 3m3 skid for input and export into and from the silo. • Deployed attached by rope. • Fully extended up to 6m length. • Chain driven system, not hydraulic cylinders. • Collapses vertically in failure mode allowing the rake to exit from the silo • Raking does not apply forces to the civil structure
  • 6. NES Solution - Waste levelling Silo Rake • The rake ensures waste is levelled for flat retrieval to avoid loading the civil structure of the silo with forces derived from the collapsing of unlevelled waste. • Silo rake fits inside a standard 3m3 skid for input and export into and from the silo. • Deployed attached by rope. • Fully extended up to 6m length. • Chain driven system, not hydraulic cylinders. • Collapses vertically in failure mode allowing the rake to exit from the silo • Raking does not apply forces to the civil structure
