The US Army, Fox Business reports, plans to build nuclear “microreactors” at five of its bases — Fort Bragg, Fort Campbell, Fort Hood, Fort Benning, and Fort Drum — over the next two years, with at least 15 more to follow later.
Why? To, the report says, “strengthen the military’s energy security and reduce its reliance on potentially vulnerable power grids.”
The idea certainly makes sense for a military base, but it makes sense for everyone, everywhere else, too.
The biggest security and reliability worry with electricity isn’t that an enemy missile or bomb will take out a power plant. It’s that an attack or accident somewhere along the 650,000 miles of high-voltage transmission lines and 6.3 million miles of distribution lines criss-crossing the US will stop that power from getting delivered.
A drunk driver hits a pole. A defective or damaged transformer explodes. A computer suddenly stops juggling chainsaws to correctly operate some part the increasingly complex and interconnected “grid” system. And the lights go out, somewhere. Maybe just on your block, maybe in a million households.
Most of the proposed to solutions to these problems seem to be about making the “grid” more “robust,” more interconnected, more complex, and more centralized. That’s a move in the wrong direction.
The “grid” is a sprawling Rube Goldberg machine that evolved over the course of the 20th century based on the now false notion that large numbers of consumers must get their electricity from large, central power plants.
The problem with that is that when something breaks in one place, people in other places suffer. In 2003, a “cascading grid failure,” caused by sagging power lines short-circuiting on tree branches in Ohio, blacked out eight US states and the Canadian province of Ontario.
Technology advances, and it doesn’t have to be “grid” technology. These days, many consumers who lost power in 2003 could, reasonably affordably, get their electricity from their own rooftop solar panels or backyard wind turbines. And for those who don’t, smaller community-level systems make more sense than a central computer pushing watts down many miles of vulnerable line, through multiple switching steps from far-flung plants.
The 20-megawatt nuclear reactors the army’s buying could each, in civilian context, power as many as 20,000 homes — about twice as many as found in the median US county. Combined with wind and solar — at both household and utility scale — there’s no reason why populations can’t become far more self-reliant and secure so a power problem in Akron doesn’t black out Ann Arbor.
If that sounds obvious, it is. So obvious that even the US Army has figured it out (as an old Marine, I naturally believe they’re not terribly bright). The rest of us should get with the decentralization/localization program.
