Recent developments in BWR water chemistry control

Description

Studies in the U.S. have shown that if the oxidizing power and the impurity content of the BWR coolant are controlled below specified values, Intergranular Stress Corrosion Cracking (IGSCC) of susceptible material can be stopped. These conditions can be obtained by the addition of small amounts of hydrogen to the reactor feedwater while maintaining reactor water conductivity below 0.3 μS/cm. U.S. experience with this technology is reviewed. The role of water chemistry variables on the buildup of Co-60 on reactor piping is also discussed. The role of trace impurities have been investigated experimentally. An optimum water chemistry which reduces IGSCC and Co-60 buildup is described. (author)
