Mini Nuclear Power Plants Could Power 20,000 Homes (Update)
The small energy modules were originally designed by Otis "Pete" Peterson and other scientists at Los Alamos National Laboratory in New Mexico. Now, the technology is being commercially developed by Hyperion Power Generation, which recently announced that it has taken its first orders and plans to start mass production within five years.
"Our goal is to generate electricity for 10 cents a watt anywhere in the world," said John Deal, CEO of Hyperion. "[The nuclear plants] will cost approximately $25 million each. For a community with 10,000 households, that is a very affordable $2,500 per home."
Because of their small size, the mini power plants can be assembled relatively quickly and transported by truck, rail or ship to remote locations, even places that currently do not have electricity. The power plants provide an alternative to current nuclear plants, which are large, expensive, and take about 10 years to build. Also, large-scale power plants don´t fit the needs of small populations or areas without available land. Hyperion´s modules can be connected together to provide energy for larger populations, as well.
In addition, the Hyperion modules have no moving parts to wear down, and never need to be opened on site. Even if opened, the small amount of enclosed fuel would immediately cool, alleviating safety concerns. "It is impossible for the module to go supercritical, ´melt down,´ or create any type of emergency situation," the company states on its Web site. Because the Hyperion plants would be buried underground and guarded by a security detail, the company explains that they´ll be out of sight and safe from illegitimate uses. Further, the material inside wouldn´t be appropriate for proliferation purposes.
"You would need nation-state resources in order to enrich our uranium," Deal said. "Temperature-wise it´s too hot to handle. It would be like stealing a barbecue with your bare hands."
The reactors need to be refueled about every seven to ten years. After five years of generating power, Hyperion says that the module produces a total waste of about the size of a softball, which could be a candidate for fuel recycling.
Hyperion now has more than 100 orders for its modules, mostly from the oil and electricity industries. The first order came from a Czech infrastructure company called TES, which specializes in water plants and power plants. TES ordered six modules and optioned another 12, with the first planned to be located in Romania.
Hyperion plans to build three manufacturing plants, with the goal of producing 4,000 mini nuclear modules between 2013 and 2023. Next year, the company will submit an application to build the modules to the Nuclear Regulatory Commission.
While acknowledging that the commercial development of mini nuclear plants is a lofty goal, Hyperion believes that the potential benefits of the technology make the effort well worthwhile. Along with bringing electricity to remote locations, the Hyperion modules could also be used to provide clean water for the 25% of the world´s population that currently does not have access to clean water. The modules can provide power to pump, clean, and process water, which in turn can help decrease disease, poverty, and social unrest.
Update (November 12, 2008): The Nuclear Regulatory Commission (NRC) contacted PhysOrg.com to state that the NRC has no plans to review the Hyperion design in the near future, although the NRC and Hyperion have had preliminary talks. Because the Hyperion design is unique, the NRC expects that it will take significant time to ensure safety requirements. In a response to a letter from October 2008, the NRC stated:
“Hyperion Power Generation is in the early stages of development of this design, and very little testing information is available for this design concept. Hyperion Power Generation has indicated that it will submit technical reports to support a pre-application review in late FY 2009. The NRC cannot engage in any meaningful, formal technical interaction with the potential applicant until we receive those reports. Because of the very limited amount of test data and lack of operating experience available for a uranium hydride reactor, the NRC staff anticipates that a licensing review would involve significant technical, safety, and licensing policy issues.”
