Condemned manner and device of radioactive contamination steam generator

摘要

(57) Abstract It is locked in the tube floor (6) and the many heat exchanger tube which is buckled in U forma the steam generator which was contaminated with the radioactivity which it possesses (4) in order it abolishes to treat (2), the heat exchanger tube (4) the tube floor (6) is disconnected at in the basis of this invention, the steam generator (2) the dome (12) is separated, the bend (42) can be caught the heat exchanger tube (4) in turn with friction join. The heat exchanger tube which it can be caught (4) deforms that preliminary and pulls the rolling roll device (26) through in order to decrease the buckling radius and makes a foolish mistake, the press device (26) is introduced in order to compress flatly.
