METHOD FOR NUCLEAR REACTOR LOOP DEACTIVATION Russian patent published in 1997 - IPC

Abstract RU 2077748 C1

FIELD: nuclear energy technology. SUBSTANCE: radiation situation amelioration is achieved while reconditioning or repairing works by corrosion radiation product removal exception from technological channel to nuclear reactor loop. After fuel extraction tube-made protecting shield is placed and fixed in technological channel of nuclear reactor. Shield length is made not less then central part of technological channel length within active zone of nuclear reactor and shield diameter is corresponding to minimal diameter of technological channel. Finally reactor loop is treated by deactivating solution using. EFFECT: more enhanced technology of reactor loop deactivation. 2 dwg
