METHOD FOR METERING OVERLAP OF TELESCOPIC JOINT IN UPPER LOOP WITH GRAPHITE COLUMN FLANGE OF PRESSURE-TUBE REACTOR

fast reactors. SUBSTANCE: telescopic joint is exposed to alternating magnetic field, response signal is picked up and used to determine changes in magnetic reluctance of adjacent sections in telescopic joint; amount of overlap is found by space between these changes; frequency of alternating magneti...

Zusammenfassung:fast reactors. SUBSTANCE: telescopic joint is exposed to alternating magnetic field, response signal is picked up and used to determine changes in magnetic reluctance of adjacent sections in telescopic joint; amount of overlap is found by space between these changes; frequency of alternating magnetic field acting on telescopic joint is 50-500 Hz. EFFECT: provision for direct overlap check without extracting and replacing process channel. 2 cl, 2 dwg
