Nuclear waste is stored on site at reprocessing facilities. Kr is released during the reprocessing of fuel rods from nuclear reactors. Nuclear reprocessing can make this waste reusable. Uranyl nitrate is important for nuclear reprocessing. China plans to develop fast breeder reactors and reprocessing. This is undertaken at a nuclear reprocessing plant. China plans to develop fast breeder reactors (see CEFR) and reprocessing. This fuel is produced in the so-called "open" (i.e., no nuclear reprocessing) nuclear fuel cycle. Reprocessing endoscopes involves over 100 individuals steps. A TWR also accomplishes most of its reprocessing within the reactor core. The high level disinfection of endoscopes occurs during a multi-step process called reprocessing. Iodine-129 is one of the major radioactive elements released from reprocessing plants. Sellafield Ltd. This included the reprocessing and waste storage facilities. Compared to classical PUREX reprocessing, pyroprocessing can be more compact and produce less secondary waste. The waste can be easily retrieved for reprocessing.
