1.0 INTRODUCTION

l The purpose of this report is to verify the structural adequacy of the pressure boundary components of the Model 100 Reactor Coolant Pumps for the South Texas Project Unit No. 1. Verification is essentially based on the

}

analyses presented in the generic stress reports of References 10.4 through 10.10.

The design requirements for the TGX pumps are prasented in Section 6.0, Any difforences between tne design requirements for TGX and those considered in the generic reports are discussed and resolved in this report. Any additional analysis generated by the TGX design requirement:, is included in Section 8.0.

The stress analysis of the nonpressure boundary components for the TGX pumps 15 found in Reference 10.13.

SUMMARY

AND CONCLUSIONS Based on a detailed review of all the design and analysis requirements for the TGX reactor coolant pumps, it is concluded that the generic stress reports (References 10.4 through 10.10) are applicable to the TGX analysis. Therefore, based on those generic reports and other analyses included in this report, it is concluded that the pressure boundary components for the TGX reactor coolant pumps satisfy all specific requirements of the E-Specs (References 10.2 and 10.3)

., andtheASMECode(Reference 10.1).

A complete stress summary for the M100 pressure boundary components for TGX is given in Section 7.0 of this report.
