Method for unclogging an electromagnetic filter and an installation for carrying out said method

Image Number 3 for United States Patent #4249994.

An electromagnetic filter of the type provided with a magnetizable packing and placed in the water circuit of a nuclear reactor is cleaned by a method which first consists in isolating the filter from the circuit, then subjecting it to a series of washing and draining-off cycles. The washing operation consists in withdrawing a fraction of water from the circuit and introducing it substantially at the temperature and pressure of withdrawal and under such conditions as to impart turbulent flow to the water within the packing. The draining-off operation consists in discharging the wash water contained in the filter.
