2 Nuclear Decommissioning Authority Background to the NDA Our sites, challenges & achievements Supply Chain Chaplecross Cooling Towers

3 Nuclear Decommissioning Authority Established under the Energy Act 2004 Came into existence in 2005 Purpose is to decommission and clean-up legacy nuclear sites Non-departmental public body responsible to Dept. of Business, Energy and Industrial Strategy (BEIS) Owns the sites on behalf of Government Employs ~250 people (18,000 in the Estate) Budget 3.3bn / year ($4.3bn) Total 120+ year liability: > 117bn (undiscounted) ($160 bn) bn range 161bn (discounted) ($210 bn)

Feb 2017: NDA Nuclear Archive opens in Scotland March 2017: 10 year old NDA / NNL /DOE Statement of Intent extended for 5 years Apr 2017: UK National Radioactive Waste Inventory published

5 Roles & Responsibilities NDA Subsidiary PBO: UK Nuclear Waste Management (UKNWM) AECOM, Studsvik UK, AREVA PBO: Cavendish Fluor Partnership PBO: Cavendish Dounreay Partnership Cavendish, CH2M, AECOM

6 Strategy Themes and Topics Site Decommissioning and Remediation o Driving strategic theme - all other strategies support its delivery o o Need for understanding of end state near term affordability vs long term cost trade off Introduction of interim states to describe the journey Spent Fuels o THORP and Magnox reprocessing plants will complete reprocessing by 2020 o Consolidate Exotic fuel from Dounreay at Sellafield Nuclear Materials o Consolidate Pu stocks at Sellafield and uranics at Capenhurst o Support Government on the development of Pu disposition options Integrated Waste Management o Ensure wastes are managed in a manner that protects people and the environment, now and in the future, and provides value for money o Covers solid VLLW, LLW, ILW, HLW, SF, Pu, U disposition, & liquid & gaseous discharges, plus non raw o GDF & safe interim storage Supported by Critical Enablers o HSSEQ, R&D, Supply Chain Development o International Relations

7 Sellafield

8 Sellafield Progress Legacy Ponds & Silos Pile Fuel Cladding Silo: installation of steel doors to allow access to retrieve the waste: James Fisher Nuclear, Shepley Engineers, Bechtel, Cavendish, BMT Magnox Swarf Storage Silo: a breakthrough in the management of ILW storage is set to accelerate progress and save hundreds of millions of pounds First Generation Magnox Storage Pond: First sludge retrievals completed from the pond Nuvia, Amec, Hertel & Cavendish Pile Fuel Storage Pond: bulk stocks of fuel removed = hazard cut by 70% ; first sludge removed December 2016

9 Dounreay

10 NaK destruction Dounreay achievements Demolition work 2 LLW vaults completed DFR Pond drained and decontaminated ready for demolition. NaK destruction completed (68t) Local authority planning permission granted for the Shaft and Silo Project New equipment installed to remove breeder fuel from DFR reactor vessel Final cell in DMTR demolished Shaft & Silo New Low Level Waste Facility Dounreay Shaft & Silo PFR clean-up

11 Magnox

12 Bradwell Will be first Magnox site to reach C&M phase completion of all near-term decommissioning Key Milestones Weather-proof aluminium cladding encasing reactor buildings complete June 2016 All underground waste vaults emptied first for Magnox FED either dissolved or treated & size reduced for disposal at LLWR Ponds Decontamination walls floor & ceiling decontaminated over 4 year period

13 Magnox achievements C&M Chaplecross Asbestos strip All Magnox former generating sites are in transition through the following phases: Defuelling removal of fuel from reactor and transported to Sellafield for reprocessing Care and Maintenance (C&M) preparations removal of hazards such as sludges/ resins/ asbestos C&M reactor buildings & ILW store are left in a safe state until Final Site Clearance Final Site Clearance Provision of a GDF will enable final decommissioning of the sites to take place SGHWR Reactor Dismantling James Fisher Nuclear, Kaefer Use of divers at Dungeness A & Sizewell Underwater Construction Corp.

14 The NDA Estate - LLWR Low Level Waste Repository near Drigg has operated as a LLW disposal facility since 1959 Compacted wastes come from Sellafield by rail Other waste arrives via road from facilities such as hospitals and research establishments LLW is disposed of in engineered concrete vaults Vault 9 opened in 2010 Key emphasis on recycling and reusing material to reduce the volumes being disposed of at LLWR VLLW to special licenced landfill Ongoing Site preparation for construction of Final Cap for Trenches 1 to 7 and Vault 8 Ongoing Decommissioning of Plutonium Contaminated Material facilities Low Level Waste Repository near Drigg has operated since 1959 LLW is disposed of in engineered concrete vaults Key emphasis on recycling and reusing material to reduce the volumes being disposed of at LLWR VLLW to specially licenced landfill Application of Waste Management Hierarchy: % of LLW disposed of / 5% diverted % of LLW disposed of / 90% diverted 100 year lifetime (including Nuclear New Build)

15 Geological Disposal Development

16 NDA R&D Notable Successes Scallop dredger Vitrification Innovus dredging scallops to radioactive sludge NDA & Innovate UK LaserSnake2 DRP Vitrification for Diverse Waste Types Createc Unmanned Aerial Systems Forth Engineering, University of Manchester & Sellafield- Latro Robotic Spider Underwater Construction Ltd divers working cutting skips in fuel storage ponds Collaborating with USDOE Robotics theme for WM2018 UAS LaserSnake2 Dungeness divers Latro the Spider

17 Supply Chain 2016/ bn ( 2.0 bn) Tier 2 supply chain spend > 50% of total NDA spend Collaborative procurements: 159m ( 189m) in 2010 > 400m ( 476m) in 2015 Small Medium Enterprise (SME) spend: 13% in 2013 > 21% in 2015 Target of 29% this year, 31% by 2020 Four main strategic principles : open, transparent, timely and consistent communications at all levels; optimised supply chain processes; optimised supply chain relationships; exploring synergies with other nuclear clients and industries. Our Site Licence Companies maintain procurement

18 INS Where specific NDA Intellectual Property is of interest, NDA s subsidiary, International Nuclear Services, is authorised by NDA to provide direct access to NDA technology and experience Engagement with UK Engineering firms will allow practical deployment of NDA experience globally

19 INS INS manages access to NDA s intellectual property All aspects of the NDA estate experience is commercially available INS is already applying this experience to civil projects in Asia and Europe Areas of particular interest may include: Reprocessing technology Decommissioning & Waste Management Package maintenance facilities Transportation systems
