U.S. Nuclear Regulatory Commission Approves Key Safety Aspect to NuScale Power’s Advanced Reactor Design

NuScale successfully demonstrates approach that allows its SMR to
be safe without need for electrical power

WASHINGTON–(BUSINESS WIRE)–The U.S. Nuclear Regulatory Commission (NRC) has concluded that
application of NuScale Power’s novel safety design approach eliminates
the need for class 1E power for its small modular reactor (SMR). Class
1E is the regulatory standard set for the design of safety-related
nuclear power plant electrical systems. In its newly released Safety
Evaluation Report, the NRC approves NuScale Power’s “Safety
Classification of Passive Nuclear Power Plant Electrical Systems”
Licensing Topical Report, where the company established the bases of how
a design can be safe without reliance on any safety-related electrical
power. Currently, all nuclear plants in the U.S. are required to have
class 1E power supplies to ensure safety. The NRC has limited its
approval to only NuScale Power’s design. NRC’s conclusion is a key step
in the review process of NuScale’s Power Module Design Certification
Application (DCA).

“We appreciate the NRC staff’s focused and thorough analysis of the
safety and reliability our SMR design offers and for issuing their
findings so early in our DCA review,” says NuScale Power Chief Operating
Officer and Chief Nuclear Officer Dale Atkinson. “Our approach to safety
is a first in the nuclear industry and exemplifies the inherent safety
of NuScale’s SMR. This validation brings us another step closer to
achieving our mission of delivering scalable advanced nuclear technology
to produce the electricity, process heat, and clean water needed to
improve the quality of life for people around the world.”

The NRC’s review of NuScale’s DCA began March 2017 and the NRC’s final
report approving the design is expected to be complete by September
2020. Once approved, certified NuScale SMRs will be available to
domestic customers to be licensed for construction and
operation. NuScale Power is the only company to have submitted an SMR
DCA. Regulatory approval will support its first U.S. deployment by the
mid 2020’s, further establishing NuScale as the leader in SMR technology.

About NuScale Power, LLC

NuScale Power, LLC is developing a new kind of nuclear plant; a safer,
smaller, scalable version of pressurized water reactor technology – a
technology initially developed and tested at Oregon State University.
Fluor Corporation (NYSE: FLR), a global engineering, procurement, and
construction company with a 60-year history in commercial nuclear power,
is the majority investor in NuScale. NuScale's design offers the
benefits of carbon-free nuclear power and reduces the financial
commitments associated with giga-watt size nuclear facilities. NuScale's
technology is also ideally suited to supply energy for district heating,
desalination, and process heat applications.

At the heart of our technology is the fully factory fabricated NuScale
Power Module™, an integral reactor vessel surrounded by a high pressure
steel containment, which when coupled to its factory fabricated power
generation equipment can produce 50 megawatts of electricity. A NuScale
power plant can house up to 12 of these modules for a total facility
output of 600 megawatts (gross). The scalability afforded by the modular
design allows customers to incrementally increase facility output to
match demand. The NuScale Power Module™ is premised on well-established
nuclear technology principles with a focus on integration of components,
simplification or elimination of systems, and use of passive safety
features resulting in highly reliable operation underpinned by an
extremely strong safety case and unparalleled asset protection, making
it suitable to be sited at locations closer to where electricity or
process heat are needed.

NuScale is headquartered in Portland, Oregon and has offices in
Corvallis, OR; Rockville, MD; Charlotte, NC; Richland, WA; Arlington,
VA; and London, UK. For more information visit: www.nuscalepower.com
