2. What is a NuScale Power Module?
A NuScale Power Module (NPM) includes the reactor vessel, steam generators, pressurizer and containment in an integral package that eliminates reactor coolant pumps and large bore piping (no LB-LOCA)
Each NPM is 50 MWe and factory built for easy transport and installation
Each NPM has its own skid-mounted steam turbine-generator and condenser
Each NPM is installed below-grade in a seismically robust, steel-lined, concrete pool
NPMs can be incrementally added to match load growth - up to 12 NPMs for 600 MWe gross (~570 net) total output 2

4. Coolant Flow Driven By Physics
Convection – energy from the nuclear reaction heats the primary reactor coolant causing it to rise by convection and natural buoyancy through the riser, much like a chimney effect
Conduction – heat is transferred through the walls of the tubes in the steam generator, heating the water (secondary coolant) inside them to turn it to steam. Primary water cools.
Gravity – colder (denser) primary coolant “falls” to bottom of reactor pressure vessel, cycle continues 4

8. NuScale Announces Major Safety Breakthrough Wall Street Journal April 16, 2013
NuScale design has achieved the “Triple Crown” for nuclear plant safety. The plant can safely shut-down and self-cool, indefinitely, with:
No Operator Action
No AC or DC Power
No Additional Water
Safety valves align in their safest configuration on loss of all plant power.
Details of the Alternate System Fail-safe concept were presented to the NRC in December 2012. 8

19. Construction Cost Summary
Overall EPC Overnight Plant Costs
($1,000,000)
5078 $/kWe net
$ 5,078 per kWe net
Note: Delivered costs shown are in 2014 $’s.

20. NuScale Levelized Cost of Electricity Estimates (LCOE)
NuScale LCOE results of $98-$108/MWhr (2015 $’s)
Key Assumptions:
Financing is 55% debt and 45% equity
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

21. Levelized Cost in 2015 US Dollars
LCOE Breakdown
Levelized Cost in 2015 US Dollars
FOAK with Regulated Utility Financing (IOU)
55% debt at 5.5%, 45% equity at 10%
FOAK with Municipal Financing
100% debt at 3.5%, no equity
$ 108 USD
$ 74 USD
Note: Capital costs reflect the Fluor SE estimate completed in 2014.
