The object of the invention to improve the corrosion of carbon steel in the Primaerkreislauf of water-cooled, water-moderated energy reactors during the standstill regime, is achieved by a rapid transition from the reductively effective protection of the steel surface is forced to oxidative passivation by addition of peroxides, in particular H22O2, whereby the intervening, corrosive active area is crossed quickly. The additions are in the range of 1-1,000 mg / l, with the p H value must be kept greater than 7.2. |
