#2 A close to ideal non-proliferation agreement could be reached with nuclear-coveting 3rd world countries: pebble bed reactors. Simply put, pebble beds are ceramic balls with radioactive material mixed in. They lie on a floor with indentations in it, like hundreds of eggs in cartons. They need miminal technical support and give off a fixed amount of heat. Advantages are that they are smaller power plants, cannot become supercritical or meltdown, and are built over a deep pit, so that when the balls are exhausted, they drop straight down for permanent disposal--no reprocessing needed. Though they produce enough energy for commercial use, they do not produce enough to enrich plutonium, and no other weapons grade isotopes are produced in their use. This solves one big problem: if a country says it wants nuclear power for peaceful uses, then pebble bed reactors are the way to go. If it wants weapons, then it wants more conventional reactors. The technology for pebble beds is easier than conventional reactors, and China is planning to produces hundreds of them. So there really is no excuse, or effective pretense that the larger, more powerful reactors are needed. In fact, if the Chinese are successful with their reactors, pebble beds would be much more economical for the US to use in the future, now that most of our nuclear plants are far beyond their projected useful lifespans. Practically speaking, a typical US State could have one or two, and the more populous States could have half a dozen each. |

#1 "Saudi Arabia will not watch as its neighbors develop nuclear weapons" Fine and dandy. Be sure to turn your heads when we blast the snot out of Iran. |
