Plutonium is a heavy, radioactive, man-made, metallic element used in the production of nuclear energy.

NEI Nuclear Notes. Barack Obama on Nuclear Energy. What’s This? Powered by Blogrunner … The advantage of sodium is that it leaves the neutron spectrum skewed to fast neutrons and thus breeds more plutonium. But, it needs highly enriched fuel and produces products that have serious proliferation problems. Placing such a reactor where there are only about 800 civilians around seems like an invitation to steal the fuel. Alaska’s governor should learn a little more about …

North Korea Trying to Enrich Uranium, South Says North Korea appears to be enriching uranium, potentially giving the state that tested a plutonium-based nuclear device in May another path for making atomic weapons, South Korea’s defense …

Consideration of a nuclear reactor usually summons up colossal size as at, say, Pennsylvania’s Three Mile Island. But just as yesteryear’s atomic bomb has been reduced to a pellet with a 5-millimeter diameter, reactors in a nuclear ….. It is smaller than ordinary reactors, but its coolant is liquid sodium and uses a fuel mix of plutonium dioxide and uranium dioxide. Uranium “breeds” additional plutonium to produce energy. However, river water was at hand and the …

It’s many times more efficient and easier to just build a nuclear reactor in your country under the guise of generating electricity. Some countries will successfully argue, “If the U.S. is going to add hundreds of new reactors then why … Getting out the plutonium is a well understood process. Simple. Iran will have no problem making a bomb, it’s just a question of time. Oh, one point I would like to make. It only took the U.S. about 7 years after the first atomic bomb …

Using Thorium reactors do not breed plutonium, and can, in fact, be designed to “burn” plutonium into non-weapons grade material and, thus, decrease weapons proliferation. Additionally, Thorium nuclear reactors can help eliminate spent …

North Korea said earlier in June it would “weaponise” its plutonium stocks and start enriching uranium for a light-water nuclear reactor. “It is clear that they are moving forward,” Mr Lee said on Tuesday. …

It is a fast nuclear reactor known as the Integral Fast Reactor (IFR) that was developed by a team of hundreds of scientists working for more than 20 years at our top government national laboratory for nuclear energy (Argonne National Laboratory, at its branches in Illinois and Idaho). ….. Compare this one-time $3 billion investment to the $10 billion that will be spent on the AREVA Mixed Oxide (MOX) plant, which is being built to dispose of only 33 tons of plutonium. …
