ctions II.4.a, b, d, and e. Regulatory Guide 1.44, "Control of the Use of Sensitized Stainless Steel," describes acceptance methods for preventing integranular corrosion of stainless steel components. Furnace-sensitized material should not be allowed, and methods described in this guide should be followed for cleaning and protecting austenitic stainless steels from contamination during handling, storage, testing, and fabrication, and for determining the degree of sensitization that occurs during welding. Regulatory Guide 1.31, "Control of Ferrite Content in Stainless Steel Weld Metal," describes acceptance criteria for assuring the integrity of welds in stainless steel components of these systems. 3. Other Materials All materials for use in this system must be selected for their compatibil- ity with the reactor coolant, as described in Articles NB-2160 and NB-3120 of the Code. The tempering temperature of martensitic stainless steels and the aging temperature of precipitation-hardening stainless steels should be specified to provide assurance that these materials will not 4.5.1-3 Rev 2 - July 1981 deteriorate because of stress corrosion cracking in service. Acceptable heat treatment temperature include aging at 10500 - 11001F for Type 17-4 PH and 1050OF for Type 410 stainless. 4. Cleaning and Cleaniness Control Onsite cleaning and cleanliness control should be in accordance with Regulatory Guide 1.37, "Quality Assurance Requirements for Cleaning of Fluid Systems and Associated Components of Water-Cooled Nuclear Power Plants," and ANSI N45.2.1-1973, "Cleaning of Fluid Systems and Associated Components During Construction Phase of Nuclear Power Plants." The oxygen content of the water in vented tanks is not required to be controlled. Vented tanks with deionized or demineralized water are a normal source of water for final cleaning or flushing of funished surfaces. Halogenated hydrocarbon cleaning agents should not be used. III.
