Description
This report presents a procedure for estimating the current condition and residual life of safety-related cast stainless steel components in light water reactors (LWRs). The procedure accounts for loss of fracture toughness caused by thermal embrittlement and includes the following: a review of design and fabrication records, inservice inspection records, and operating history; a fracture mechanics evaluation to determine the required toughness at end-of-life using worst-loads and worst-flaw indications; current and future toughness estimates; and criteria regarding continued service, repair, or replacement of the component being evaluated. The report discusses the available Charpy V-notch impact energy, fracture toughness, tensile strength, fatigue resistance, and fatigue-crack growth data, and presents two methods for assessing the degree of thermal embrittlement: metallurgical evaluation and analytical modeling of inservice degradation. 74 refs., 21 figs., 5 tabs
