CIRCULATING CIRCUIT COOLANT CLEANING SYSTEM Russian patent published in 1994 - IPC

FIELD: nuclear power engineering. SUBSTANCE: coolant cleaning system for circulating circuit 1 has vertical sediment column with inclined bottom 8, its flow area being 10 to 15 times larger than of circuit 1 accommodating filter element 5. Cleaning system also incorporates trapping mechanism 6 with pipe connections 7 to accumulate impurities. In the course of coolant cleaning part of impurities settle down in sediment column and part of them are extracted from flow by filter element 5. EFFECT: improved design. 2 cl, 1 dwg
