E.M. #4932 Page i ABSTRACT This report evaluates the pressure boundary components of the Model 100 pump in respect to the ASME Code Section III criteria.

The conditions considered are:

r

1. Startup - Heatup 2

2. Steady State Operating

3. Shutdown - Cooldown These, along with the specified design conditions and hydrostatic testing, are included in the evaluation.

This report will become part of a series of reports for the Model 100 pump. Forthcoming reports will pertain to the following:

nozzles, support feet, heat exchangers, and auxiliary nozzles.
