What Does it Take to Bring a New Design to Market?

Vision—improvements vis-à-vis existing designs (safety, fuels,

efficiency, costs, speed of deployment)

Time—concept, modeling, prototype, testing, materials (NuScale will

be ~24 years)

Money– For NuScale ~$1B+, currently ~$12MM+/month,

Market—Unless someone is willing to buy it there is no point

Government Support—this is a heavy lift for private sector

Licensing—certainty of dedicated resources, requirements,

schedule

Supply chain—lots of new stuff needs to be made and constructed

People—600+ currently on project at NuScale

WARNING: New fuels, non-LWR’s, new materials will take longer—

design, testing, demonstration, licensing

Blazing the Trail to Commercialization

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 (gross) 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)

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

SMR Technology Leader – Collaborative Research

• From 2012 to 2015, NuScale Power

staff has engaged in nearly 60

research collaborations with

external organizations

• NuScale is collaborating in more

than $24 million of externally

funded research, primarily from

DOE-sponsored university and

laboratory grants

18 completed, 37 active or

pending, and 4 inactive

collaborations

Engagements with 13 different

companies, 5 US national

laboratories, and 15

universities

• Internationally, NuScale has

partnered with two universities (UK

and Italy), one national laboratory

(UK), and one commercial company

(Finland)

Making it Real

Commercialization Plan and Status

The Genesis of Program WIN

June 2010: Idaho Governor Butch Otter became Chair of

Western Governors Association (WGA) and sponsored Western

nuclear energy policy

June 2011: “The Future of Nuclear Energy:

Shaping a Western Policy” published:

discusses SMR’s explicitly

Feb 2012: Otter creates Idaho Leadership in

Nuclear Energy (LINE) Commission

June 2012: Utah Governor Gary Herbert

becomes WGA Chair and sponsors development

of a 10-year energy plan-patterned after Utah 10-year plan

June 2013: WGA 10-yr plan unveiled with stated goal to “Find

ways to accelerate the introduction of SMRs into the

marketplace.”

Lowering the Barriers for Market Entry

High capital costs set the bar high for building new nuclear

power plants, especially in unregulated markets.

These barriers can be lowered by giving proper value to the

environmental benefits of nuclear power.

Examples:

To really combat anthropogenic climate change, a carbon price, or

some other disincentive that includes natural gas is essential.

Renewable portfolio standards should be redefined as clean energy

portfolio standards and include new nuclear generation.

Subsidies for clean energy should be equal across the board for all

clean energies on a per kW basis.

Unregulated market structures will need to be reformed for new builds

of nuclear power units to be viable.
