Abstract
The effect of the purification filter for the first-loop water coolant in marine nuclear power systems on maintaining the regulated indicators (pH, ammonia concentration, chlorides, iron, and the total specific activity of radionuclides) at a prescribed level is examined. It is shown that constant operation of the purification system does not guarantee reliable accident-free operation of the nuclear power system. The operating regulations for the system should be changed as follows: purification is used on the removed cooled nuclear power system with small deviations of the content of chloride ions or in the process of stopping the nuclear power system if it is necessary to remove the loop the radionuclies contained in the surface deposits.
