Method for treatment of primary coolant medium of a pressurized water nuclear reactor

Patent number: 5307391

Abstract: A method for treating the primary coolant of a pressure water reactor by controlling its efficiency through the H.sub.3 BO.sub.3 content in the coolant is described. Hydrazine hydrate is continuously added to the coolant cycle of a nuclear reactor which is charged for energy generation in such amounts that its content is 5.multidot.10.sup.-6 to 5.multidot.10.sup.-2 g/kg coolant. Excess hydrogen is removed from the coolant leaving a content of no more than 100 n.ml/kg.
