METHOD OF MEASURING THE LITHIUM CONCENTRATION OF THE COOLING WATER OF A NUCLEAR REACTOR

摘要

In a process for measuring lithium concentration in nuclear reactor primary cooling water, containing boric acid for reactor core reactivity control and lithium hydroxide for pH control, by measuring the electrical conductivity of a sample taken from the primary circuit, the boron concentration is also determined and is used together with the conductivity measurement to calculate the lithium concentration.
