Almost always deployed to maximum (40GW) Big increase in 2040s is partly due to increased demand (for heating and transport), and partly because the additional renewables need backup

UK Constraints In The Deployment Of Nuclear Capability & Capacity To Expand Programme Programme Delivery Experience Sites Optimum Contribution In The Mix Are there suitable and sufficient sites for nuclear deployment or will this become an additional constraint? Nuclear capacity in the 2050 energy system
Competition For Sites? Potential For Competition For Sites Between Nuclear and New Thermal Plants With CCS CO 2 disposal sites in Irish and North Seas CO 2 storage and transport infrastructure expected to be located on the coast nearer the disposal sites New thermal plant requires CCS connection and access to suitable and sufficient cooling water Installed Capacity 16 GW Site Capacity 40 GW? 75 GW? Note: the policy of the Scottish Government is not to support the deployment of new nuclear but to focus on renewables instead Potential coastal locations to access CCS transport and disposal infrastructure
Can Small Nuclear Build A Niche Within The UK Energy System? For SMRs to be deployed in UK: technology development to be completed range of approvals and consents to be secured sufficient public acceptance of technology deployment at expected locations against either knowledge or ignorance of alternatives deployment economically attractive to o reactor vendors o utilities and investors o consumers & taxpayers Small Nuclear Large Nuclear FID Final Investment Decision Realistic objective for SMRs to be economically attractive to all stakeholders
Niche For Small Nuclear In The UK? Single Revenue Stream Multiple Revenue Streams Containment structure 1. Baseload Electricity Containment structure 1. Baseload Electricity 2. Variable Electricity To Aid Grid Balancing Control rods Steam Generator Generator Control rods Steam Generator Generator Turbine Turbine Reactor vessel Condenser Waste Heat Rejected To The Environment Reactor vessel Condenser 3. Heat Recovery To Energise District Heating Systems

ETI Projects Delivered Power Plant Siting Study Explore UK capacity for new nuclear based on siting constraints Consider competition for development sites between nuclear and thermal with CCS Undertake a range of related sensitivity studies Identify potential capacity for small nuclear based on existing constraints and using sites unsuitable for large nuclear Project schedule June 2014 to Aug 2015 Delivered by Atkins for ETI following competitive open procurement process System Requirements For Alternative Nuclear Technologies Develop a high level functional requirement specification for a black box power plant for baseload electricity heat to energise district heating systems, and further flexible electricity to aid grid balancing Develop high level business case with development costs, unit costs and unit revenues necessary for deployment to be attractive to utilities and investors Project schedule August 2014 to Aug 2015 Delivered by Mott MacDonald for ETI following competitive open procurement process Outputs to be used in ETI scenario analysis to determine attractiveness of such a black box power plant to the UK low carbon energy system
So What Have We Learned? Power Plant Siting Study System Requirements For Alternative Nuclear Technologies ETI ESME Scenario and Sensitivity Studies For Nuclear
Siting Data Applied In ESME Capacity constraints applied in ESME
Future Heat Networks Almost 50 GB urban conurbations with sufficient heat load to support SMR energised heat networks Would theoretically require 22 GWe CHP SMR capacity
Distribution Of SMR Site Capacity SMR site capacity from the Power Plant Siting Study - Further potential locations likely to be found; the limit has not been explored SMR Capacity (GWe) By Cooling Water Source SMR Capacity (GWe) By Regional Location To Meet Demand SMR Capacity (GWe) By Distance From Potential District Heating Network
Assumptions: Prices
Cost Reduction Model - Factory & Learner Target CAPEX for a first fleet of SMRs providing baseload electricity is challenging
Target CAPEX: CHP SMR Target CAPEX more achievable for a first fleet of SMRs as CHP Plants
Updated ESME Baseline Capacity with 35 GWe Large Gen III+ and without SMRs
Updated ESME Baseline Capacity with 35 GWe Large Gen III+ with SMRs available SMR deployment capacity influenced by: Speed to first UK SMR operations Capital cost ( /kwe) 2050 Nuclear Capacity 1 GWe legacy (SZB) 35 GWe Gen III+ 16 GWe CHP SMRs
Requirement For SMR Flexible Power Delivery Reduction in SMR summer overnight power generation in this model run Flexibility is likely to be important to be able to modulate power to help balance the grid The flexibility here is diurnal, within a seasonal pattern Remember also the impact from intermittent renewables and associated peak generation
ESME Analysis Results For Nuclear In UK Large reactors optimal here Baseload Flexible Extra-flex Electricity only SMR power plant Baseload power (continuous full power operation between outages) Operated with daily shaped power profile when required to help balance the grid (Slightly) reduced baseload power with extra storage & surge capacity Combined Heat & Power (CHP) plant As above but with heat As above but with heat As above but with heat SMRs optimal here
