This report is a summary of the Boiling Water Reactor Owners Group Intergranular Stress Corrosion Cracking (BWROG IGSCC) Research Program. This Program consisted of two phases; a Phase 1 was performed during the period 1980 through 1983, while the duration of Phase 2 was from 1984 through 1988. The objective of Phase 1 was to develop the technology to extend BWR piping service lifetime and to minimize outage time required for inspection and repair due to IGSCC of stainless steel piping. Phase 1 tasks included: Plant Problem Resolution, Remedy Development and Remedy Application. During Phase 1, the EPRI Nondestruction Evaluation Center (EPRI NDE Center) was established in Charlotte, North Carolina. Co-located in the Center was the BWROG Pipe Remedy Application and Training Facility. The objective of Phase 2 was to continue the efforts initiated in Phase 1 and to meet the new management issues which resulted from the demands imposed on the BWR Owners by the Nuclear Regulatory Commission and new problems identified in Phase 1. The research in Phase 2 consisted of six tasks; (1) BWR Recirculation Piping Systems Replacement and Repair, (2) Detection and Sizing of IGSCC in BWR Piping, (3) Testing of Interim Repairs and Remedies for Cracked Piping, (4) BWR Water Chemistry, (5) Qualification of BWR Decontamination and Passivation Techniques, and (6) Technology Transfer. The results of Phases 1 and 2 and the EPRI contributions are presented in this report. A bibliography is included containing about 320 papers published as part of this 2-phase research program. Sections have been indexed separately for inclusion on the data base.
