Abstract: A method for protecting the components of the primary system of a boiling water reactor, especially against stress cracking corrosion, includes feeding a reducing agent into the primary coolant in order to reduce the number of substances having a oxidizing effect or in order to modify the electrochemical potential of the component surfaces covered with an oxide layer to negative values. An alcohol that can be oxidized in the conditions of a reactor is fed in as a reducing agent, preferably in a liquid form, into the primary coolant. The component surfaces are provided with a blank coating or a single intrinsic oxide coating.

Abstract: The invention relates to a method for counteracting the escape of radioactive iodine from a cooling system of a water-cooled nuclear reactor, a reducing agent being introduced into the cooling system of the reactor during a shutdown of the reactor and/or during a subsequent after-cooling operation.

Abstract: For dosing lithium in cooling water containing cationic impurities or for reducing cationic impurities, the invention guides cooling water cycle through a first side of an electrodialysis unit and guides a concentration cycle through a second side of the electrodialysis unit. Cationic impurities are filtered out of the medium of the concentration cycle with a selective ion exchanger that is disposed in the concentration cycle.
