NRC approves V.C. Summer’s second license renewal
Dominion Energy’s V.C. Summer nuclear power plant, in Jenkinsville, S.C., has been authorized to operate for 80 years, until August 2062, following the renewal of its operating license by the Nuclear Regulatory Commission for a second time.

The design of steam generator components operating in the creep range often involves sophisticated methods of analysis requiring a variety of test data. Creep, relaxation, stress rupture, and fatigue data are required, and in many cases it is necessary to extrapolate the data to the long-term service conditions. The 9% Cr—1% Mo steel in the normalized and tempered condition has a relatively high proof strength and good creep rupture strength and ductility properties; furthermore, its fatigue strength is little affected by creep. The % Cr—1% Mo steel is not so strong, and its creep-fatigue properties have not yet been sufficiently well defined to provide reliable design guidance in this area. Alloy 800 has a good rupture strength, and although design guidance for creep fatigue is available, recent results suggest that the values may need to be reviewed.
