Nuclear-vessel design involves consideration of changes in metal properties resulting from fast-neutron irradiation effects. This paper outlines precautions and design steps which can cope with these effects and insure safe operation of PWR closed-cycle-type reactor vessels for their planned life expectancy. Illustrations show workable stress levels as a function of temperature for the reactor-vessel material in nonirradiated and irradiated condition. A plot of equivalent pressure temperature relationships is shown as a guide for the plant operator during plant start-up and shutdown periods.
