Application Summary AI generated

This standard specifies nuclear criticality safety criteria for steel-pipe intersections containing aqueous solutions of fissile materials. It is applied in nuclear fuel cycle facilities, such as reprocessing plants or waste treatment operations, where fissile solutions flow through intersecting pipe geometries. The criteria ensure that the intersection configuration prevents accidental criticality by controlling parameters like pipe diameter, spacing, and solution concentration.
