erent accessibility conditions or when other essential variables listed in the Code, Section IX, are changed. (c) The qualification and requalification tests required by 2.c(1)(a) and (b) above may be waived provided that the joint is to be 100% radiographed or ultraspnicaly examined after completion of the weldment. Examination procedures and acceptance standards should meet the requirements of the ASME Code Section III. Records of the examination reports and radiographs should be retained and made part of the Quality Assurance documentation of the completed weld. (2) Regulatory Guide 1.37, "Quality Assurance Requirements for Cleaning of Fluid Systems and Associated Components of Water- Cooled Nuclear Power Plants," and ANSI Standard N 45.2.1-1973, "Cleaning of Fluid Systems and Associated Components During Construction Phase of Nuclear Power Plants," describe acceptable procedures for cleaning and handling Class 2 and 3 components of the steam and feedwater systems. Vented tanks with deionized or demineralized water are an acceptable source of water for final cleaning or flushing of finished surfaces. The oxygen content of the water in these vented tanks need not be controlled. (3) Acceptance criteria for nondestructive examination of tubular products are given in the ASME Code, Section III, Paragraphs NB/NC/ND 2550 through 2570. III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. To ascertain that the acceptance criteria given in subsection II of this SRP section are met, the reviewer examines the areas listed in subsection I for the required information, in accordance with the following procedures: 10.3.6-4 Rev. 2 - July 1981 1. Fracture Toughness of Class 2 and 3 Components The reviewer determines which components of the steam and feedwater systems will be made of carbon or low alloy steels, and determines that their fracture toughness properties are in
