STP-GSI-191-EMCB-RAI-1 Item 3.k of Reference 1 requested licensees to summarize the structural qualification results and design margins for various components of the sump strainer structural assembly. In Reference 2, STPNOC, the licensee, provided a qualitative response regarding the structural analysis without any supporting quantitative data. Additional information is needed regarding actual and allowable stresses and design margins for the various components of the sump strainer structural assembly to clarify the inherent level of conservatism employed in the design. This information was not STPNOC submittals (References 3 and 4).
Please summarize the structural qualification results, including the actual and allowable stresses, and design margins for the various components of the sump strainer structural assembly.
