2.12 We reported in 2012 that Sellafield Limited had made poor progress on its portfolio of 14 major projects. Many projects fall within the legacy ponds and silos programmes, providing bespoke equipment, buildings and systems to remove, treat, package, move and store waste. Some relate to the operation of the site and reprocessing spent nuclear fuels. We reported delays and cost overruns on projects in planning and design, where schedules and costs may be particularly uncertain because of the uncertainties of the volume and nature of the waste and the technical solutions needed to manage the decommissioning. We also reported poor progress on projects in the construction phase. The Authority has provided updated cost and schedule data for the projects that we reviewed (Appendix One). Two of the original projects in planning and design have since been cancelled or incorporated into other projects. Three of the major projects in construction have been completed, with little further cost escalation or delay since 2013, and two projects have moved from planning and design into construction. One further major project has entered the planning and design phase. Therefore, of the original fourteen projects, nine remain active, with three in planning and design and six in construction.
