'ANSI N45.2.5-1974, "Supplementary Quality Assurance Re quirements for Installation, Inspection, and Testing of Struc tural Concrete and Structural Steel During the Construction Phase of Nuclear Power Plants." Copies may be obtained from ý1'the Ame'ican Society of Mechanical Engineers, 345 East 47th Street, New York, New York 10017. C. REGULATORY POSITION The requirements and guidelines that are included in ANSI N45.2.5-1974 for installation, inspection, and testing of structural concrete and structural steel during the construction phase of nuclear power plants are generally acceptable to the NRC staff and provide an adequate basis for complying with the pertinent quality assurance requirements of Appendix B to 10 CFR Part 50, subject to the following: 1. Subdivision 1.5 of ANSI N45.2.5-19.74 states: "Other documents that are required to be included as a part of this standard are identified at the point of reference and listed in Section 8 and the Appendix of this Standard." The specific applicability or acceptabil ity of documents listed in Section 8 has been covered separately in other regulatory guides. Other standards and codes listed in ANSI N45.2.5-1974 provide useful guidance for the installation, inspection, and testing of structural concrete and structural steel. Prior to use of these other referenced codes and standards, however, the suitability of the standard or code should be reviewed for the particular application under consideration. 2. Subdivision 2.1 of ANSI N45.2.5-1974 includes general provisions for planning the installation, inspec tion, and testing of structural concrete and structural steel. In this regard the provisions of Subdivision 2.1 of ANSI N45.2.5-1974 should be used in conjunction with Regulatory Guide 1.55, "Concrete Placement in Cate gory I Structures." 3. Subdivision 4.5 of ANSI N45.2.5-1974 provides, in part, that inspection of concrete placement shall be performed to verify the adequacy of concrete
