Abstract

PURPOSE: To prevent stress, corrosion and crack of the reactor, by adding Li7OH to the primary cooling water, with lithium (Li7) type ion exchange resin applied to a desalter of reactor clean system, to keep the primary cooling water in alkaline state of pH8 to 10.
CONSTITUTION: For a pH tempering compound of primary cooling water in the boiling light-water reactor, for instance, LiOH, NaOH, KOH, etc. will be used. The cooling water is always exposed to a strong radiation. As a material, with addition agent not secondaryly activated, not seized by a desalting device in the core clean system to purify a slight amount of impurities with the core made partially bypassing, and relatively easy to be procurable, the most suitable is Li7OH. Li7, with a secondary activity not charged, by using lithium type (Li7) ion exchange resin to the core clean system desalting device, because of no consumption of Li7OH in the cooling water, will be suitable for pH tempering alkaline compound.
