NuScale Power
Small Modular Reactors
The Future of Nuclear Energy
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
What is a NuScale Power Module?
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

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

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.

Construction Cost Summary
Overall EPC Overnight Plant Costs($1,000,000)
Note: Delivered costs shown are in 2014 $’s.
$ 5,078 per kWe net
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
NuScale Levelized Cost of Electricity Estimates (LCOE)
LCOE Breakdown
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
Levelized Cost in 2015 US Dollars
Note: Capital costs reflect the Fluor SE estimate completed in 2014.
