Peter Montague: Is Nuclear Power Green?

The Unquenchable Fire Is Nuclear Power Green?
Counter Punch By PETER MONTAGUE 4 Nov 08 We are told that nuclear power is about to achieve a “green renaissance,”……………………scientists have developed two sets of criteria that we can use to judge the “greenness” of competing technologies. The first is called “The 12 principles of green engineering” and the second is “The 12 principles of green chemistry.”………………….Anyone can readily see that nuclear power violates green engineering principles #1 (prefer the inherently nonhazardous) and #2 (prevent instead of manage waste). Nuclear power produces radioactive wastes and “spent fuel,” which are are exceptionally hazardous and long-lived. Just mining the fuel — uranium — has littered the western U.S. (and other parts of the world) with mountainous piles of radioactive sand (“uranium tailings“), which no one knows how to stabilize or detoxify, and which continually blow around and enter water supplies and food chains……………………………Nuclear power also violates green engineering principles #9 (design for easy disassembly) and #11 (design for commercial re-use) because, after a nuclear power plant has lived out its useful life, many of its component parts remain extremely radioactive for centuries or aeons. Large parts of an old nuclear plant have to be carefully disassembled (by people behind radiation shields operating robotic arms and hands), then shipped to a suitable location, and “mothballed” in some way — usually by burial in the ground. An alternative approach is to weld the plant shut to contain its radioactivity, and walk away, hoping nothing bad happens during the next 100,000 years or so. In any case it’s clear that nuclear power violates principles #9 and #11 of green engineering…………..When we compare nuclear power against the principles of green  chemistry, we can readily see that it violates #1 (prevent waste), #3 (avoid using or creating toxic substances), and #10 (avoid creating persistent substances) because of the great toxicity and longevity of radioactive wastes. It also violates #7 (use renewable, not depleting, raw materials) because the basic fuel, uranium, is not renewable. Plans for extending the life of global uranium supplies all entail the use of “breeder reactors,” which create plutonium. But plutonium itself violates green chemistry principles 1, 3, 4 and 10. The scientist who discovered plutonium (Glenn Seaborg) once described it as “fiendishly toxic.” Plutonium is also the preferred material for making a rogue atomic bomb, which is why the New York Times has called the world’s existing supplies of plutonium “one of the most intractable problems of the post-cold-war era.”[1]
Lastly, nuclear power plants produce what is called “spent fuel” — a misnomer if there ever was one. “Spent” makes it sound tired and benign. There is nothing benign about “spent fuel.” It is tremendously radioactive — so much so that it must be stored in a large pool of water to keep it cool. If someone accidently (or malevolently) drained the “spent fuel pool” that exists on-site at nearly every nuclear reactor, the “spent fuel” would spontaneously burst into flame and burn out of control for days, releasing clouds of highly-radioactive cesium-137 all the while. Green chemistry principle #12 says our technologies should be chosen to minimize the potential for accidents such as releases and fires. By this standard, nuclear power does not measure up.
