e tube.)* 4. The fracture toughness of the ferritic materials is acceptable because it conforms with 10 CFR 50.55a, Appendix G to the ASME Code, and Appendix G to 10 CFR Part 50. 5. The welding of the ferritic materials of the steam generator is acceptable because it is performed in accordance with 10 CFR 50.55a, paragraph D-1210 of Appendix D to Section III of the ASME Code, and RG 1.34, 1.43, 1.50, and 1.71. (The fabrication and processing of austenitic stainless steel is acceptable because these activities are performed in accordance with 10 CFR 50.55a and RG 1.28, 1.31, 1.34, 1.36, 1.44, and 1.71. In addition, the guidance in NUREG-0313 will be followed, and the yield strength of austenitic stainless steel will be limited to 620 MPa (90,000 psi).)* *Indicates material within parentheses “as applicable.” 5.4.2.1-18 Draft Revision 4 – April 2016 6. The requirements of Appendix B to 10 CFR Part 50 have been met with respect to onsite cleaning because the onsite cleaning and cleanliness controls during fabrication will conform to the recommendations of RG 1.28. The controls placed on the secondary coolant chemistry are in agreement with the staff’s technical position, and the additives to be used will limit the susceptibility of the steam generators to corrosion given the operating environment so that the inservice inspection program can manage any degradation that may occur. In addition, the secondary water chemistry program is (will be)* consistent with the latest revision of the Standard Technical Specifications. (The primary coolant water chemistry program is acceptable for the materials unique to the steam generator.)* 6. The provisions for accessing the secondary side of the steam generator are acceptable because tools may be inserted to inspect and remove (1) corrosion products and contaminants that may lead to corrosion and (2) foreign objects (including loose parts) that may affect tube integrity. 7. Reasonable assurance of the satisfactory
