On the basis of summarizing up the installation and operation situation of condensate polishing system in domestic nuclear power plants

and combining with the situation of installing condensate polishing system in thermal power plants with parameters above subcritical values

the necessity of installing condensate polishing system in pressurized water reactor nuclear power plants has been pointed out.Owing to the quality of intaking water and effluent water for condensate polishing system in domestic pressurized water reactor nuclear power plants having no corresponding specification and standards

the practical data of condensate polishing system in USA have been given.Directing against the operation situation of condensate polishing system in nuclear power plants

it is recommented that the condensate polishing system with 50% rate condensate quatity has to be installed for inland nuclear powerplants

and condensate polishing system with 100% rated condensate quantity has to be installed in nuclearpower plants situated in coastal regions.
