摘要：

Every 30 to 40 million, or so, operating hours a destructive reaction is observed in one of the approximately 4000 large compressors that move UF6 through the gaseous diffusion plants. Despite its infrequency, the reaction can be costly in terms of equipment and time. Laboratory experiments reveal that the presence of moderate pressures of UF6 actually cools heated aluminum, although thermodynamic calculations indicate the potential for a 3000-4000°C temperature rise. Within a narrow and rather low (6 or UO2F2. 1. An initiating source of heat must be provided. 2. The film protecting the aluminum must be breached. 3. Reaction products must not be allowed to build up and smother the reaction.
