parts A, B and C of Section II of the Code. Regulatory Guide 1.85, "Code Case Acceptability ASME Section III Materials," describes acceptable Code cases that may be used in conjunction with the above specifications. Fracture toughness of the materials shall be as stated in SRP Section 10.3.6, subsection 11.1. a. Austenitic Stainless Steels To meet the requirements of GOC 4 relative to compatibility of components with environmental conditions; GDC 14 with respect to fabrication and testing of the reactor coolant pressure boundary so as to have an extremely low probability of abnormal leakage, of rapidly propagating failure, and of gross rupture; and the quality assurance requirements of Appendix B of 10 CFR Part 50 the following guidelines should be used: 1. Cold worked austenitic stainless steels must have a maximum 0.2% offset yield strength of 90,000 psi to reduce the probability of stress corrosion cracking in ESF systems. 6.1.1-4 Rev. 2 - July 1981 Laboratory stress corrosion test and service experience provide the basis for this criteria. 2. Regulatory Guide 1.44, "Control of the Use of Sensitized Stainless Steel," describes acceptable criteria for prevent- ing intergranular corrosion of stainless steel components of the ESF. Furnace-sensitized material should not be allowed in the ESF, and methods described in this guide should be followed for testing the materials prior to fabrication, and for ensuring that no deleterious sensiti- zation occurs during welding. 3. Branch Technical Position MTEB 5-7, "Material Selection and Processing Guidelines for BWR Coolant Pressure Boundary Piping," describes acceptable criteria for the use of austenitic stainless steel piping in boiling water reactors. (See SRP Section 5.2.3.) 4. Regulatory Guide 1.31, "Control of Ferrite Content in Stain- less Steel Weld Metal," describes acceptable criteria for assuring the integrity of welds in austenitic stainless steel ESF components. The control of delta ferrite content of weld
