[en] A stress analysis has been performed on proposed modifications to the Emergency Core Coolant System right and left side. For the right side thermal expansion and seismic loads were considered. Results of a previous report using dead weight, design LOCE, and LOCA loads were treated as valid and not repeated here. For the left side LOCE loading only was considered. The results of a previous analysis using dead weight, thermal, and LOCE loads were treated as valid and again not repeated here. Review of the analysis indicated that both proposed modifications pass the requirements of the ASME Boiler and Pressure Vessel Code Section III for Class 1 and 2 piping
