ACTIVE FILTER OF A NUCLEAR POWER STATION SUMP TANK

An active filter of a sump tank at a nuclear power station ensures safe operation of the facility in the event of an accident by providing an uninterrupted supply of a cooling liquid to the core of the nuclear reactor. During an accident, foreign matter and debris appear in the cooling liquid and clog a bottom filtering element of the active filter. The liquid flow is fed through a top filtering element of a filter housing, thus causing a turbine to rotate, which rotation causes the purified liquid to be drawn from the filter housing through filter pipes which feed said purified liquid by centrifugal force through jets to filtering elements, while forcing the foreign matter and debris away from said filtering elements and, thus, performing the self-cleaning of the filter.
