    摘要: A method of controlling a single temperature type water/hydrogen isotopic exchange reaction plant comprising an electrolytic system, an exchange reaction column and a recombining system for separating degraded heavy water into product and waste both of which have a stable concentration. The control method comprises controlling an extracting quantity of waste so that a heavy water concentration of water at an intermediate portion of the reaction column is kept constant, and controlling an extracting quantity of product so that a water quantity inside the exchange reaction plant is kept constant.
