Any flow blockage in subassemblies can lead to overheating of fuel pins in them. Sodium flow mainly through fresh subassemblies (SAs) is measured in PFBR. Hydraulic characteristics of core flow measurement is carried out. Experimental studies indicate 58.5% of coolant flow through sensor measuring region. A different measuring geometry for flow measurement in blanket and storage SAs.
