Small Modular Reactor (SMR) Nuclear Technology

Fluor is a majority investor in NuScale Power, a small modular reactor (SMR) technology company, who submitted the first-ever SMR design certification application to the U.S. Nuclear Regulatory Commission in December 2016.

SMRs are defined by the International Atomic Energy Agency as those with an electrical output of less than 300 megawatt electrical (MWe).

The modular reactors would be manufactured at a fabrication plant and delivered to a site for installation. Factory production can increase quality, reduce cost and shorten construction schedules. Capital costs are lower for smaller SMR plants, opening the possibility of nuclear power to a wider group of potential owners. The smaller scale modular design provides more flexibility for installing at sites in remote locations, or for replacing retiring fossil plants. Due to these benefits, SMRs are drawing a great deal of attention from governments, utilities (large and small), communities and the nuclear industry.

Safe - NuScale's passive safety systems, using natural circulation for emergency feedwater cooling, eliminates the need for external emergency power. The system is submerged in a below-ground water pool in an earthquake resistant building, making it seismically robust.

The U.S. Nuclear Regulatory Commission concluded application of NuScale Power’s safety design approach eliminates the need for class 1E power for its small modular reactor. - January 2018

Modular - Production of modular component at U.S. and international facilities helps lower costs and reduce lead times and flexible for changing demand volumes.

Scalable - Power generating capacity can be increased as needed by installing additional NuScale modules.

Reliable - Designed for baseload production with capacity factors in excess of 90 percent.

Off-the-shelf Technologies - Minimizes the need for additional research and development. Simplified design, moving the primary coolant (water) to natural circulation, eliminates the need for primary coolant pumps and external power.

Small electric grid application - The small size allows for applications that cannot accommodate large-scale plants.
