Abstract

PURPOSE: Changes in liquid temperature are detected as changes in electric resistance by a heat sensing element, and the errors owing to the temperature variation of electric conductivity are compensated, whereby the concentration of boron in primary cooling water of a pressurized water reactor as a boric acidmannitol complex is measured at high accuracy.
