| Popis: | Intergranular stress corrosion cracking (IGSCC) has been responsible for more than 1,000 cases of cracking in austenitic stainless steel piping systems in boiling water reactors (BWRs). This paper presents the status of efforts in the United States to prevent IGSCC in BWRs during power operation by modifying the chemistry of the reactor water. The technical basis for this alternative water chemistry, called hydrogen water chemistry (HWC), is described and the results are presented of an ongoing in-plant program, at Commonwealth Edison's Dresden-2 plant, to verify the HWC concept and systematically assess the consequences of using it in an operating BWR. In addition, progress toward implementation of HWC at other U.S. plants is summarized. |
