摘要： PURPOSE:To eliminate suspended impurities efficiently by permitting primary cooling water for a BWR nuclear power generating station to pass through a specific mixed bed consisting of powder or powder cationic exchange resin and anionic exchange resin for filtration. CONSTITUTION:The moisture content of cationic exchange resin and anionic exchange resin is increased from the standard value of 45-55% of the conventional gel resin to 55-75%, and a resin bed is formed using such ion exchange resins. The primary cooling water of a BWR nuclear power generating plant is filtered to eliminate suspended impurities. Two different resin bed forming means are available: a means to increase the moisture content of either one of the cationic exchange resin or anionic exchange resin from the standard value of 45-55% of the conventional gel resin to 55-75% and a means to laminate a cationic exchange resin with a moisture content of 55-75% over a mixed bed top part of the conventional ion exchange resin.

摘要： PURPOSE:To enable sufficient removal of a clad, by forming a resin floor with the degree of crosslinking of anion and cation exchange resins reduced to 7.5-3% in terms of the content of divinyl benzene to remove suspended impurities during the processing of a primary cooling water of a BWR type nuclear power generation plant. CONSTITUTION:A mixing floor is formed from a resin with the degree of crosslinking of cation and anion exchange resins reduced 7.5-3% in terms of the content of divinyl benzene to remove suspended impurities during the processing of a primary cooling water of a BWR type nuclear power generation plant. The degree of crosslinking is so low in the anion and cation exchange resins herein used to make the diffusion rate of a clad higher in a resin particle with a relatively large pores therein. The resin is elastic, not being comparatively hard. This allows a large clad adsorbing effect due to an elastic deformation of the surface of a resin during passage through water, thereby enabling production of a highly pure water with a low density of the clad in filtering and desalting operations.

摘要： PURPOSE: To contrive to recover and reuse low-electric conductive liquid waste, while saving a necessary amount of water to be used, by reserving and using the low-electric conductive liquid waste in the step of washing ion-exchange resin for its regeneration.
CONSTITUTION: The liquid waste of sluicing water 8 is sent through piping 10 to a liquid waste tank 2 and partially drained off. Since the low-electric conductive liquid waste reserved therein has the approximately same properties as those of water to be used for backwashing/regeneration, it is divided through piping 11 into two parts, individually introduced into the lower and upper sites of a cation-exchange resin tank 3 and used for the regeneration of resin. It is introduced into an anion-exchange resin tank 4 and used therein by the same way, too. Thus, the drainage of the low-electric conductive liquid waste is reduced, in its amount.

摘要： PURPOSE:To obtain high-purity water low in the concn. of crud by treating water to be treated of a condensate purifier in a steam power generation facility by both cation exchange resin and anion exchange resin whose ion exchange capacity and surface potential are regulated to the specified value. CONSTITUTION:A mixed bed is formed which consists of both cation exchange resin and anion exchange resin which has 0.9-1meq/ml.R-Cl ion exchange capacity and/or 20-35mV surface potential. Water to be treated of a condensate purifier in a steam power generation facility is filtered and desalted by the above- mentioned mixed bed. The suspendible impurities which exist in the water to be treated are removed. By this method, the ion exchange capacity and/or surface potential of anion exchange resin are made lower than a conventional method and therefore the mutual action exerted between crud and anion exchange resin is made small. Cation exchange resin easily traps crud and thereby high-purity condensate low in the concn. of crud is obtained.
