This paper presents a case study of the hydrogen water chemistry (HWC) program implemented at Duane Arnold Energy Center (DAEC). In 1985 various reactor recirculation system piping weld repairs and safe end replacements were performed at the DAEC. These weld repairs and safe-end replacements were required as a result of inter-granular stress corrosion cracking (IGSCC). In 1986, the utility decided to implement a hydrogen water chemistry program as a means of suppressing IGSCC. The paper includes a discussion of the system design basis, a brief system description, and a discussion of plant system interactions. A description of methodology developed to verify and monitor the effectiveness of the HWC system is also included.
