Proliferation process streams

In tlie PUREX process, the spent fuel and blanket materials are dissolved in nitric acid to form nitrates of plutonium and uranium. These are separated chemically from the other fission products, including the highly radioactive actinides, and then the two nitrates are separated into tv/o streams of partially purified plutonium and uranium. Additional processing will yield whatever purity of the two elements is desired. The process yields purified plutonium, purified uranium, and high-level wastes. See also Radioactive Wastes in the entry1 on Nuclear Power Technology. Because of the yield of purified plutonium, the PUREX process is most undesirable from a nuclear weapons proliferation standpoint,... 

The fluid bed processor was used as an efficient way to dry a product due to suspension of particles in the hot air stream. However, over the last 35 years, the development in the pharmaceutical industry and the proliferation of the batch fluid bed processing technology in other industries as food, polymer, detergent, etc., has provided the opportunity to use the batch fluid bed processor for granulation, coating of particles, and pelletization. The advances in the fluid bed can be attributed to several factors. The needs of formulators, the requirements of the regulators, and technological innovations from the manufacturers of these equipments are...
