NuScale Power History
 NuScale first of current US SMRs to begin
design of commercial NPP.
 NuScale technology in development and
design since 2000 (DOE) MASLWR program,
with INL, lessons from AP600/1000 ¼-scale
testing facility built and operational
NuScale Engineering Offices Corvallis, Oregon
 Electrically-heated 1/3-scale Integral test
facility first operational in 2003
 Began NRC design certification (DC) preapplication project in April 2008
 Acquired by Fluor in October 2011
One-third scale Test Facility
 ~330 FTE’s currently on project, ~$200MM
spent project life-to-date
 67 positions currently open, adding 100+
 115 patents pending/granted, 17 countries

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 45 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 540
MWe total output

Coolant Flow Driven By Physics
Convection – energy from the
nuclear reaction heats the primary
reactor coolant causing it 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 Breakthrough in Safety
Wall Street Journal April 16, 2013

10
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.
