Content:
ewer compares the limits on allowable stresses and strains in the concrete, reinforcement, structural steel, etc., with the corresponding 3.8.4-17 Draft Revision 4 – December 2012 allowable stresses specified in Subsection II.5 of this SRP section. If the applicant proposes to exceed some of these limits for some of the load combinations and at some localized points on the structure, the reviewer evaluates the justification provided to show that structural integrity will not be affected. If the reviewer determines such justification to be inadequate, the proposed deviations are identified and transmitted to the applicant with a request for adequate justification and bases. 6. Materials, Quality Control, and Special Construction Techniques. The reviewer compares the materials, quality control procedures, and any special construction techniques with those referenced in Subsection II.6 of this SRP section. If a new material not used in previous licensed cases is used, the reviewer asks the applicant to provide sufficient test and user data to establish the acceptability of such a material. Similarly, the reviewer evaluates any new quality control procedures or construction techniques to ensure that there will be no degradation of structural quality that might affect structural integrity. 7. Testing and Inservice Surveillance Requirements. For Seismic Category I structures outside containment, the reviewer verifies that monitoring and maintenance requirements for structures are in accordance with 10 CFR 50.65 and RGs 1.127 and 1.160. Any special design provisions (e.g., providing sufficient physical access, providing alternative means for identification of conditions in inaccessible areas that can lead to degradation, remote visual monitoring of high-radiation areas) to accommodate inservice inspection of other Category I structures are reviewed on a case-by-case basis. The reviewer evaluates any other testing and inservice surveillance programs on a case- by-case
