REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of component integrity issues related to steam generator tubes Secondary - None I. AREAS OF REVIEW The purpose of this review is to ensure that (1) the materials used to fabricate the steam generator are selected, processed, tested, and inspected to appropriate specifications, (2) the fracture toughness of the ferritic materials is adequate, (3) the design of the steam generator limits the susceptibility of the materials to degradation and corrosion, (4) the materials used in the steam generator are compatible with the environment to which they will be exposed, (5) the design of the secondary side of the steam generator permits the chemical or mechanical removal of chemical impurities, and (6) any degradation to which the materials are susceptible (including fracture) is avoided, can be managed through the inservice inspection program, or can be controlled through limits placed on operating parameters. Performing periodic steam generator inspections will ensure that the integrity of the steam generator is maintained at a level comparable to that in the original design requirements. The specific areas of review are as follows: 1. The selection, processing, testing, and inspection (during fabrication/processing) of the materials used to fabricate the steam generator. 5.4.2.1-2 Revision 3 - March 2007 2. The design provisions for limiting the susceptibility of the steam generator to degradation or corrosion. 3. The fabrication and processing of ferritic materials, including the fracture toughness of the ferritic materials used in the steam generator. 4. The fabrication and processing of austenitic stainless steel materials (if austenitic stainless steel is used for pressure boundary applications). 5. The compatibility of steam generator materials with the primary (reactor) and secondary coolant and cleanliness control. 6. The provisions for accessing the secondary side of the steam generator for
