Simplicity Enhances Safety
Natural Convection for Cooling Passively safe, driven by gravity, natural
circulation of water over the fuel No pumps, no need for emergency generators
Seismically Robust System submerged in a below-ground pool of
water in an earthquake resistant building Reactor pool attenuates ground motion and
dissipates energy Simple and Small
Reactor core is 1/20th the size of large reactor cores
Integrated reactor design, no large-break loss-of-coolant accidents
Defense-in-Depth Multiple additional barriers to protect against the
release of radiation to the environment
Steel containment has >10 times pressure rating than typical PWR
Water volume to thermal power ratio is four times larger than typical PWR
Reactor core has onlyfive percent of the fuelof a large reactor
160 MWt NuScale Power Module
All safety equipment needed to protect the core is shown on this picture

Containment Design
Containment volume sized so that core does not uncover following a LOCA (prevents fuel heat-up)
Large water pool keeps containment shell cool and promotes efficient post-LOCA steam condensation
Insulating vacuum significantly reduces heat transfer during normal operation requires no insulation on reactor vessel improves LOCA steam condensation rates by eliminating air prevents combustible hydrogen mixture in the unlikely event of
a severe accident (i.e., little or no oxygen) reduces corrosion and humidity problems inside containment
High Pressure Containment – Enhanced Safety

NuScale Plant Market Competitiveness, Economics & Financeability
SMR Market Potential• UK NNL* calculated the potential SMR market to be approximately 65‐85GW by
2035, 55‐75 GW excluding Russia
• This is equivalent to 1100 – 1500 NuScale Power Modules (NPMs)• At 25% market share, and 10 year deployment timeframe, 28–38 NPM / year• At 36 NPM / year, approximately 1000 workers dedicated to machining, assembling
and testing NPMs
*UK National Nuclear Laboratory “SMR Feasibility Study”, December 2014

SMRs & the Clean Power Plan (CPP)
TM28
EPA issued its proposed Clean Power Plan to regulate CO2 emissions from existing power plants under section 111(d) of the Clean Air Act
The CPP issued varying, state-specific targets; rule is not prescriptive about how to meet the targets The CPP is tough on coal plants, the largest and highest rate emitters, and many will have to close CPP 2022-2029 “glide path” matches well with NuScale first deployment in 2023 Base load power will have to come from nuclear power, CCGT or renewables + storage
Renewables + storage is currently too expensive to be used for base load demand Utilities will resist becoming overly dependent on natural gas as a fuel source
32% reduction in GHG from affected EGUs is ~100 GW of coal which could be replaced by a combination of renewables, energy efficiency and nuclear. 100 GW represents 2000 NuScale Power Modules or 175 570 MWe plants UK NNL forecast for US is 15 GW of SMR deployment by 2035
Construction Cost SummaryOverall EPC Overnight Plant Costs
($1,000,000)
Note: Delivered costs shown are in 2014 $’s.
$ 5,078 per kWe net
~10,000 man hour effort over 6 months.
Detailed equipment lists to individual valves and instruments.
Takeoffs developed for all piping, duct, wire, excavation, civil/structural materials, and architectural items.
Total equipment and commodity input over 14k line items.
All equipment tagged with building, system, unit, and safety classification.
Updated construction plan with estimate input.
84% of equipment pricing based on budgetary quotes.
Plant Cost Estimate Development
Plant Cost Estimate Assumptions Generic southeastern USA site. Labor hours based on Fluor standard unit
rates with productivity adjustments. Labor rates based on existing Fluor
project. Indirect costs based on staffing plan,
construction schedule, and temporary facility plan. Bottoms up indirect cost estimate.
Schedule based on 51 months mobilization to mechanical completion. 28.5 month critical path - first safety concrete to mechanical completion.
Class 4 estimate per AACE with an expected accuracy range of +35%/-10%.
Owners cost, estimated at $300 mm, not included in EPC estimate. Estimates for transmission, admin building, licensing, etc. carried in LCOE costs.
NuScale LCOE results of $98‐$108/MWhr (2015 $’s)Key Assumptions:
– Financing is 55% debt (@5.5%) and 45% equity (@10.0%).
– Modeled as a 40 year project life, but the plant is designed for 60 years
– Excludes owner’s costs such as:– HR and management infrastructure, central office– COLA, permits, NRC and ITAAC inspections, and
legal fees– Switchyard– Owner's project development costs– Owner's engineering services (post‐COLA)– Owner contingency
– Including an estimate of owners costs would add ~ $6/MWhr
