DESALTER FOR PRIMARY COOLING SYSTEM AND PURIFICATION METHOD FOR PRIMARY COOLING WATER IN NUCLEAR POWER PLANT WITH PRESSURIZED WATER REACTOR

摘要

PPROBLEM TO BE SOLVED: To obtain a desalter where neither fracture nor cracking appears in an anion exchange resin even if primary cooling water containing boric acid is brought into contact with the resin. PSOLUTION: The desalter for a primary cooling system 8, which purifies primary cooling water in a nuclear power plant with a pressurized water reactor, is composed by including a purification means filled with a porous anion exchange resin whose pore volume is 0.05 to 0.50 mL/g of dry resin (Cl type) and also whose average pore radius is 2 to 50 nm (Cl type). The method for purifying the primary cooling water is composed by bringing the primary cooling water in the nuclear power plant with the pressurized water reactor into contact with the porous anion exchange resin whose pore volume is 0.05 to 0.50 mL/g of dry resin (Cl type) and also whose average pore radius is 2 to 50 nm (Cl type).
