ELECTRIC DEIONIZATION APPARATUS AND SECONDARY SYSTEM LINE WATER TREATING APPARATUS OF PRESSURIZED WATER TYPE NUCLEAR POWER PLANT USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To dissolve the problem especially in secondary system line water treatment of a pressurized water type nuclear power plant by using a special electric deionization apparatus. PSOLUTION: In the electric deionization apparatus, an ion exchange resin charged in a desalination chamber consists of an anion exchange resin and all diaphragms partitioning the desalination chamber and an electrode chamber consist of an anion exchange diaphragm. In a secondary system line water treating apparatus of the pressurized water type nuclear power plant, the electric deionization apparatus is provided at a line for returning blow-down water from a steam generator to a condenser.
