accordance with ASTM C871, “Test Method for Chemical Analysis of Thermal Insulation Materials for Leachable Chloride, Fluoride, Silicate and Sodium Ions” (Ref. 6) is required to meet ASTM C795 for qualification of the insulation material. During production each lot2 of insulation material should be evaluated to demonstrate acceptability of the product under production including chemical analysis using ASTM C871. Harmonization with International Standards The International Atomic Energy Agency (IAEA) has established a series of safety guides and standards constituting a high level of safety for protecting people and the environment. IAEA Nuclear Energy Series Technical Reports provide information in the areas of nuclear power, nuclear fuel cycle, radioactive waste management and decommissioning, and on general issues that are relevant to all of the above-mentioned areas. The NRC staff identified one IAEA document pertinent to this regulatory guide, IAEA Nuclear Energy Series NP-T-3.13, “Stress Corrosion Cracking in Light Water Reactors: Good Practices and Lessons Learned” (Ref. 7), issued September 2011. The IAEA document addresses the importance of stress-corrosion cracking as one of the significant aging degradations for major components of both pressurized-water reactors and boiling-water reactors. This regulatory guide incorporates similar design and testing guidelines and is consistent with the basic principles provided in IAEA Nuclear Energy Series NP-T-3.13. Documents Discussed in Staff Regulatory Guidance This regulatory guide endorses the use of one or more codes or standards developed by external organizations and other third party guidance documents. These codes, standards and third party guidance documents may contain references to other codes, standards or third party guidance documents (“secondary references”). If a secondary reference has itself been incorporated by reference into NRC regulations as a requirement, then licensees and
