A PRELIMINARY ANALYSIS OF THE THERMAL STATES AND THERMAL STRESSES IN THE S3G/S4G PRIMARY COOLANT SYSTEM PRESSURIZER DURING COLD-START-UP
Technical Report
·
OSTI ID:4322692
A preliminary analysis of the thermal states and thermal stresses induced in the S3G/S4G primary coolant system pressurizer during cold-startup has been made. It is indicated that the results are strongly influenced by the procedure followed during startup, and consequently the present study was made for two different cases. Results for these cases are presented, and their significance is also pointed out. One of the more important assumptions made is the quantity of heat which is applied at a constant rate during the heating period and this factor is taken as being 264 kw for the present analysis. Further, it has been found that with this heating rate and the assumed pressurizer configuration several critical stress regions occur in both cases studied, and suggestions for obliviating these conditions are also included.
