NuScale Power competing for DOE $266M small modular reactor funding opportunity
13 March 2013
NuScale Power, LLC, (earlier post) will compete for the Department of Energy’s (DOE) new Funding Opportunity Announcement (DE-FOA-0000800) which outlines a plan to provide investments to private industry to support the design, licensing and manufacturing of Small Modular Reactors (SMRs). (Earlier post.)
NuScale takes a modular approach for building its power plants. Each NuScale Power Module is a self-contained and operates independently of the other modules in a multi-module configuration. However, all modules are managed from a single control room. Using light water reactor (LWR) technology, the NuScale Power Module is cooled by natural circulation, is entirely self-contained and is installed underwater and underground to maximize safety.
The basic NuScale Power Module has a thermal capacity of 160 MWt and electrical capacity of more than 45 MWe. An 80' x 15' cylindrical containment vessel module contains the reactor and steam generator—a 650-ton unit as shipped from the fabrication shop. Cost is projected to be less than $5,000/kW. The module uses standard LWR fuel in a 17 x 17 configuration, each assembly 2 meters (~ 6 ft) in length, on a 24-month refueling cycle with fuel enriched less than 4.95%.
Our design offers the DOE a plant with innovative new safety features and true scalability from 45MW to 540MW—making it adaptable to fit multiple potential applications. This FOA emphasizes the importance of an SMR technology’s ability to withstand severe natural phenomena, such as a Fukushima-type event. Our plant is designed to safely shut down and self-cool indefinitely in such an event, without AC or DC power or additional water requirements.—John Hopkins, NuScale’s chairman and CEO
The NuScale design was initially developed in 2000 under a DOE-funded research program and demonstrated in a one-third scale electrically heated test facility in Corvallis, OR, starting in 2003.
NuScale was the first US-based SMR vendor to begin discussions with the US Nuclear Regulatory Commission and has been engaged in pre-application efforts since 2008.
NuScale Power has the backing and technical assistance of Fluor Corporation, a multi-billion-dollar global engineering firm with more than 60 years in the nuclear new-build market. Fluor has designed, built or provided construction support for 20 nuclear units in the US, and provides a full range of procurement and other services to nuclear plant operators worldwide.
