teels. Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of ihe Office of Nubesr Reactor Regulation staf responsible for the review of ppUco to construt and operae nuar power plant. Te documents are made available to the public as part of the Commssons poly to Inform the nuear Industry nd the ge public of regulatory procedures and policies. Standard review pans ar not substtes for rguator guds or the Commissions regulations and compliance with th m k not required. The sandard revew plan sions r kyed to th Standard Format nd Content of Saoety Analysis Reports tor Nuclear Power Plants Not *1 sctons of the Standard Format hae a cesowplan. Pubshed standard review plains wi be revised periodically,. e app t. to ccommoda comments end to reflect new lnform toin and experience. Comme and suggestions for improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission. Office of Nuclear Reactor Regulation. Washington. D.C. MM The use of sensitized stainless steels should be controlled to prevent stress-corrosion cracking of the material during operation of the plant. Welding procedures should be controlled to reduce the probability of sensitization and microfissure formation. Cold-worked stainless steels should not have high yield stress, to reduce the probability of stress-corrosion cracking during operation of the plant. 3. Other Materials Special requirements for the other materials include tempering and aging temperatures for martensitic and precipitation-hardening stainless steels to prevent their deterioration by stress corrosion during operation of the plant. The compatibility of these materials with the reactor coolant is reviewed to assure that they will continue to perform satisfactorily throughout the life of the component. Metallic and non-metallic materials used in the control rod drive mechanism and not included in Appendix I to Section III of the ASME B&PV Code are identified. 4.
