ions to boundary conditions, cracking of sections, if any, and the dynamic behavior of masonry walls. (c) Damping values to be used for dynamic analysis shall be those for reinforced concrete given in Regulatory Guide 1.61. 3.8.4-27 DRAFT Rev. 2 - April 1996 (d) In general, for operating plants, the seismic analysis and Category I structural requirements of FSAR shall apply. For other plants, corresponding SRP requirements shall apply. The seismic analysis shall account for the variations 116 and uncertainties in mass, materials, and other pertinent parameters used. (e) The analysis should consider both in-plane and out-of-plane loads. (f) Interstory drift effects should be considered. (g) In new construction, no unreinforced masonry wall is permitted; also, all grout in concrete masonry walls shall be comparedconsolidated by vibration. 117 (h) For masonry shear walls, the minimum reinforcement requirements of ACI-531 shall apply. (i) Special construction (e.g., multiwythe, composite) or other items not covered by the code shall be reviewed on a case-by-case basis for their acceptance. (j) Licensees or Applicants shall submit QA/QC information, if available, for staff 118 review. In the event QA/QC information is not available, a field survey and a test program reviewed and approved by the staff shall be implemented to ascertain the conformance of masonry construction to design drawings and specifications (e.g., rebar and grouting). (k) For masonry walls requiring protection from spalling and scabbing due to accident pipe reaction (Y ),jet impingement (Y ), and missile impact (Y ), the r j m requirements of SRP Section 3.5.3 shall apply. Any deviation from SRP Section 3.5.3 shall be reviewed and approved on a case-by-case basis. 5. Revision of Criteria The criteria will be revised, as appropriate, based on: (a) Design review meetings with the selected licensees and their A/Es.119 (b)(a) Experience gained during review. 120 (c)(b) Additional information developed
