History of the NuScale Power Design

Starting in 2000, the U.S. Department of Energy (USDOE) funded research for the development of a small nuclear power plant that might be used in multiple applications. Idaho National Environment & Engineering Laboratory (INEEL) led the project with support from Oregon State University (OSU). At the same time, OSU was gaining international recognition for its work in the development of passive safety systems that use natural circulation to provide cooling for nuclear plants. OSU built and operated a scale model or replica of a 1000 mw and a 600 mw nuclear steam supply system to help the developer obtain US Nuclear Regulatory Commission Design Certification for those technologies.

When the DOE research project concluded in 2003, OSU scientists continued to pursue the design of a small nuclear plant that used natural circulation. Ultimately, the team at OSU built a one-third scale electrically-heated version of their plant as a test facility for this design. OSU granted NuScale Power exclusive rights to the nuclear power plant design, as well as the continued use of the test facility, through a technology transfer agreement completed in 2007.

NuScale notified the NRC in February 2008 of its intent to pursue Design Certification for its technology. The company is in the pre-application review phase with the NRC. It is on track to file its formal request for Design Certification in early 2010.

Many of the leading consultants in the nuclear industry have joined with NuScale to commercialize its technology. NuScale is designing both single-unit systems that will generate 40 Mw of electricity as well as multi-module facilities.

Kiewit Constructors, an engineering and construction company with wide experience in power generation facilities, joined NuScale as a strategic partner in early 2008. Kiewit is developing the plans for modular manufacturing and construction of NuScale power plants.
