Method for Controlling Temperature of Reactor Coolant to Reduce Amount of Boron Used in Nuclear Power Plant

摘要

PURPOSE: A method for controlling the temperature of reactor coolant is provided to reduce the amount of boron. CONSTITUTION: The temperature of coolant gradually decreases according to the degree of burnup of nuclear fuel. The temperature of the coolant is controlled by controlling the amount of second cooling water supplied to a heat exchanger(105) and the temperature of the second cooling water cooled in a condenser(113).
