Method of operating nuclear power plant, nuclear power plant, and method of controlling water chemistry of nuclear power plant

摘要: In a nuclear power plant, by injecting an amount of hydrogen small enough not to increase radiation dose rate the main steam system, ECP metallic component materials composing reactor can be decreased suppress potential occurrence IGSCC, and control easily performed, operating cost suppressed increase. Occurrence intergranular stress corrosion cracking in contact with cooling water is zirconium hydroxide into decrease electrochemical materials.
