METHOD TO CLEAN DOWNFLOW PIPES OF DRUM SEPARATORS OF NUCLEAR CHANNEL-TYPE REACTOR

摘要

FIELD: power engineering.SUBSTANCE: in the method of cleaning of downflow pipes of drum separators of a nuclear channel-type reactor by means of flushing with water, downflow pipes are flushed in each drum separator in turns by pure chemically desalinated water supplied with a flow rate of 200?250 m/hr for 12?14 minutes. Besides, the total time of flushing is divided into two stages. The first flushing is to be carried out with a flow rate of 240?250 m/hr for 7?8 minutes, and the second one - with a flow rate of 200?210 m/hr for 5?6 minutes.EFFECT: reduced duration of cleaning, reduced volume of used water for cleaning of downflow pipes of all drum separators.2 cl, 3 dwg
