In order to recycle uranium and plutonium in power plants, spent fuel has to be treated to chemically separate these elements from other highly radioactive byproducts. As it chops and dissolves used fuel rods, a reprocessing plant releases about 15 thousand times more radioactivity into the environment than nuclear power reactors and generates several dangerous waste streams. If placed in a crowded area, a few grams of waste would deliver lethal radiation doses in a matter of seconds. They also pose enduring threats to the human environment for tens of thousands of years.

Although the U.S. continued to reprocess spent fuel from military reactors, the “once through” fuel cycle was adopted by President Carter in 1977 for commercial nuclear power. Three years earlier, India had exploded a nuclear weapon using plutonium separated from power reactor spent fuel at a reprocessing facility. President Ford responded in 1976 by suspending reprocessing in the United States. President Carter converted the suspension into a ban, while issuing a strong international policy statement against establishing plutonium as fuel in global commerce. President Carter’s decision reversed some 20 years of active promotion by DOE’s predecessor, the U.S. Atomic Energy Commission (AEC), of the “closed” nuclear fuel cycle. The AEC had spent billions of dollars in an attempt to commercialize reprocessing technology to recycle uranium and provide plutonium fuel for use in “fast” nuclear power reactors.

Recycling advocates are seeking to overturn this long-standing policy and point to a new generation of “fast” reactors to breakdown plutonium so it can’t be used in weapons. Since the 1940’s, it was understood that “fast” reactors generate more subatomic particles, known as neutrons, than conventional power plants and it is neutrons which split uranium atoms to produce energy in conventional reactors. The U.S. actively promoted plutonium-fueled fast reactors for decades because of the potential abundance of neutrons, declaring that they held the promise of producing electricity and making up to 30 percent more plutonium than they consumed.
With design changes, fast reactors are, ironically, being touted in the U.S. as a means to get rid of plutonium. However, the experience with “fast reactors” over the past 50 years is laced with failure. At least 15 “fast” reactors have been closed due to costs and accidents in the U.S., France, Germany, England, and Japan. There have been two fast reactor fuel meltdowns in the United States including a mishap near Detroit in the 1960’s. Russia operates the remaining fast reactor, but it has experienced 15 serious fires in 23 years.

Okay its appears it wasn't worth the risk....tried, failed and all we have is more radioactive pollution. People seem to forget Carter was a nuclear engineer.
