SOLUTION: A certain quantity of cation-exchange resin having sulfonic acid group is sampled from the condensate demineralizer of the nuclear power plant, and is dipped in hot water for a predetermined time, and then average molecular weight of polystyrene sulfonic acid eluting in the hot water is measured by gel permeation chromatography. When the average molecular weight of polystyrene sulfonic acid is a threshold or more, the cation-exchange resin is exchanged.

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.

摘要： PURPOSE:To remove clad in resin efficiently by separating mixed resin polluted during condensate treatment into cation-exchange resin and anion-exchange resin an immersing the cation-exchange resin in an acidic aqueous solution for at least 5 hours. CONSTITUTION:Granular mixed resin of cation-exchange resin and anion- exchange resin polluted during condensate treatment in a steam power plant is separated into the cation-exchange resin and anion-exchange resin. Then, the separated cation-exchange resin is immersed in an acidic aqueous solution for at least 5 hours for regeneration. Aqueous sulfuric acid, hydrochloric acid, and nitric acid solutions are preferable for the acidic aqueous solution for cation-exchange resin treatment. Considering ability to remove clad adsorbed in the surface of the resin and operational problems, duration of the immersion treatment of the cation-exchange resin in the acidic aqueous solution is preferably 10-15 hours.

摘要： PURPOSE:To strengthen condensation treatment capacity of a power plant by forming a mixed bed by means of resin of divinyl benzene containing ratio in the given range in which resin crosslinking degree is set lower than the standard value of existing gel type resin in the filter desalting process by means of the mixed bed composed of cation-anion exchange resin. CONSTITUTION:When condensation of a thermoelectric power plant is treated, a mixed bed is formed by means of resin of in the range of 7.5%-3% divinyl benzene containing ratio lower than the standard value (8%) of crosslinking degree of cation exchange resin and/or anion exchange resin for the existing gel type resin in the filter desalting process by means of the mixed bed composed of grain or powder-like cation exchange resin and anion exchange side. Because of the reasons such as crosslinking degree of anion-cation exchange resin is lower compared with the existing mixed bed filter desalting process, pores in resin phases are large and the diffusion speed into the resin grains of clad is fast and also resin not rigid comparatively and clad adsorption effect generated by elastic deformation of resin surface at the time of applying water, water of low clad concentration and high purity can be prepared at the time of filter desalting operation.

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 reduce a residual quantity of strong basic anion exchange resin by transferring the most part of ion exchange resin of small gravity on the top layer through an opening section of a resin transfer tube while introducing sluicing water and pressurized water, and then effecting a backwashing. CONSTITUTION:A mixed resin layer transferred from a desalting column is backwashed, and after the same is separated into two layers, strong acidic cation exchange resin (SAR1) with large gravity is separated into a sublayer and a strong basic anion exchange resin (SBR2) into a top layer, sluicing water Q1 is introduced from an intermediate sluicing tube 11 and pressurized water 8 is introduced from the upper section of the column to transfer the most part of SBR into an anion regenerating column. Next, backwashing water 3 is introduced from a water collection device 10 at the lower section of the column, and at the same time or after several minutes after backwashing, sluicing water Q2 is introduced from the intermediate sluicing tube 11 with the flow velocity larger than Q1. Further, SBR2' is transferred from an open section 4' of a resin transfer tube 4.

摘要： PURPOSE:To enhance the quality of treated water by reducing a chlorine type anion resin formed by reducing an anion resin remaining at the time of distribution and transfer as low as possible, by properly arranging a transfer sluicing pipe and a pair of resin transfer pipes in a separation tower. CONSTITUTION:In separating and transferring the strong basic anion exchange resin (hereinbelow referred to as SBR) 2' low in specific gravity remaining on a strong acidic cation exchange resin (hereinbelow referred to as SAR) layer 1 high in specific gravity, the transfer sluicing pipe 7 traversing the center of a tower provided below a boundary line and resin transfer pipes 8 having opening parts 8', 8'' in positional relation so as to cross said pipe 7 crosswise are provided. The resin layer SAR 1 having high specific gravity is brought to a flowable state by backwashing water and water is further blown off upwardly from the pipe 7 provided in the intermediate part of said resin layer. By this method, the resin SBR 2 having low specific gravity is gathered to the opening parts 8', 8'' of the transfer pipes 8 to be transferred.
