E.M. #5003 Page i ABSTRACT This report evaluates the ability of the Model 100 pump casing and nozzles to resist the external pipe design loads as specified in the general equipment specification. This is done by comparing the calculated stresses which these loads impose on both the casing and e

nozzles, with the ASME Code,Section III allowable criteria.

E.M. #5003, Rev. 1 Page 2 II. SumARY AND CONCLUSIONS The Model 100 Pump casing and casing nozzles meet the external design loading requirements as specified in Section III of the ASME Code -

Reference 4, including Appendix F to the Code - Reference 5.

The results and comparisons with the allowable criteria are sunnarized in the following Tables I and II for the suction nozzle loading, and Tables III and IV for the discharge nozzle loading.
