Nuclear Power in a Small Package: LANL Has Stake
In Mini-Reactor
Dec 15 - McClatchy-Tribune Regional News - Raam Wong Albuquerque Journal,
N.M.
It sounds like something out of a sci-fi movie: A nuclear reactor smaller
than an SUV that could produce electricity for 20,000 homes.
It would have no weaponsgrade material, produce very little waste and would
need refueling once every five to 10 years.
You could bury it in the backyard -- not that you would want to.
This scenario is real.
A company partly owned by Los Alamos National Security, the consortium that
runs the national lab, and using technology from the lab hopes to get
regulatory approval and start manufacturing the minireactors within a few
years.
The company, Hyperion Power Generation, already has a couple hundred orders
pending and is proposing to mass-produce thousands of the reactors that
would provide clean, reliable energy to industries and communities in remote
areas.
The units could power military installations and islands, for example, or
perhaps pump and clean water in developing countries.
About 5 feet wide, the Hyperion Power Module would leave the factory sealed
and be carried by truck, train or ship to its destination, where it would be
buried underground.
The reactor would power a steam turbine that could produce enough
electricity for 20,000 American homes at a cost of 6 to 8 cents per kilowatt
hour.
Public Service Company of New Mexico sells electricity for just more than 8
cents per kilowatt hour -- a figure that takes into account transmission,
distribution and other expenses, as well as the power generation.
Hyperion CEO John Grizz Deal said in a telephone interview from Denver that
more investors want to write checks for orders than the company knows what
to do with.
Hyperion is considering Lea County in southeastern New Mexico and Idaho
Falls, Idaho, as possible homes for its manufacturing facilities. More
plants would be built abroad.
The plan is to manufacture 4,000 units that sell for $25 million a pop.
The reactor was invented by then-LANL scientist Otis "Pete" Peterson. The
lab licensed the technology to Hyperion for commercialization. Deal said Los
Alamos National Security -- the lab's for-profit corporate manager -- owns
part of the company.
Hyperion has said the reactor will need about three more years of work
before it can be deployed.
The company plans to apply for design certification and a manufacturing
license from the U.S. Nuclear Regulatory Commission. It will be up to a
reactor's owner to obtain an NRC site permit and operating licence, Deal
said.
Controlling fuel
The key to the reactor's slim figure is the nonweaponsgrade uranium that
makes it run.
Uranium hydride -- uranium plus hydrogen -- both fuels the reactor and
controls its nuclear activity. If it gets too hot, the uranium sheds
hydrogen, slowing down the nuclear fission.
The idea of developing compact reactors has been bandied around for decades.
In 1964, the U.S. Atomic Energy Commission developed a pamphlet titled
"Power Reactors in Small Packages." The thought was that portable reactors
could be used in polar exploration, disaster recovery efforts or at radar
stations.
"Although we all know that the history of such power plants was very short,
these ideas are now being regenerated, revitalized by advancing technology
and a continuing need," Nuclear Regulatory Commission member Peter Lyons
said during a conference in September.
Los Alamos National Laboratory first used uranium hydride in efforts to
design a safer nuclear weapon, Deal said.
But getting the N RC's immediate support may be a challenge.
Lyons, the NRC member, told the High Temperature Reactor 2008 conference
that applications to build small reactors were "at the bottom of the NRC's
priority list."
The commission wants to ensure such reactors are commercially viable before
beginning licensing procedures, the trade publication Nuclear New Build
Monitor reported last month.
Deal isn't worried about a lack of attention.
"The rest of the nuclear energy industry just thinks we're adorable," said
Deal, who in 1992 founded a successful software company called LizardTech
using technology developed at LANL.
Part of the solution
The Hyperion reactors would need to be dug up after five to 10 years of use
and sent back to the factory for refueling. The company says the reactors
will produce waste about the size of a softball.
Deal said a mechanical failure is unlikely because the reactors don't use
fuel rods or other moving parts, while a unit would emit less radiation than
the public is exposed to on a daily basis.
Still, even if Hyperion is a smashing success, Deal acknowledges the
reactors will be only part of the solution.
"If we sold 4,000 of our units it would be a fraction of the electric demand
around the world."
Deal views emissions-free nuclear reactors as one of the best ways of
addressing global warming, whereas other alternative energies like solar and
wind have no good way of storing the energy.
"I'm a left-wing environmentalist nutball, and I've embraced nuclear
energy," Deal said. "We think this is important."
