Nuclear Facility Safety Analysis. Safety analysis reports document the analysis and the potential consequences of accidents and abnormal occurrences at nuclear facilities. For those facilities which process, store, and handle plutonium and other fissile materials, nuclear criticality safety analysis is a required element of the facility safety analysis report. The process includes the identification of hazards in the facility(including nuclear criticality safety hazards), the identification and development of potential scenarios involving nuclear criticality concerns, the development of failure modes and the potential effects of the accident, and the consequences of the accident. 1, record 5, English, - nuclear%20facility%20safety%20analysis

Criticality risk varies with the degree of enrichment in235U, the mass of enriched uranium, the presence of a moderator (such as water), and the geometry of the solid uranium mass. Sufficient masses of enriched uranium to create a criticality risk may be present in deposits internal to process equipment, or may accrue from waterborne transport of soluble uranium (either in the process equipment or during improper aqueous decontamination operations). 1, record 7, English, - criticality%20risk

Chemical holding or storage vessel. Especially designed or prepared holding or storage vessels for use in a plant for the reprocessing of irradiated fuel. The holding or storage vessels must be resistant to the corrosive effect of nitric acid. The holding or storage vessels are normally fabricated of materials such as low carbon stainless steels, titanium or zirconium, or other high-quality materials. Holding or storage vessels may be designed for remote operation and maintenance and may have the following features for control of nuclear criticality :(a) walls or internal structures with a boron equivalent of at least 2%;(b) a maximum diameter of 175 mm(7 in.) for cylindrical vessels; or(c) a maximum width of 75 mm(3 in.) for either a slab or annular vessel. 1, record 16, English, - chemical%20storage%20vessel
