Filter medium for strainers used in nuclear reactor emergency core cooling systems

摘要: A filter medium for strainers used in the emergency sump of a nuclear power plant ECCS. The is employed with double wall, concentric tube type strainer modules. preferably constructed woven or knitted stainless steel wire material and shaped cylinder so that it can be inserted between two walls, such manner water passes through must pass filtered by before pumped to reactor core. bottom module held place an x-shaped retainer. creates varied approach velocity fluid results non-uniform fibrous debris accumulation on strainer, insuring acceptable hydraulic head loss.
