Modernizing I&C for operations and maintenance, one phase at a time
The two reactors at Dominion Energy’s Surry plant are among the oldest in the U.S. nuclear fleet. Yet when the plant celebrated its 50th anniversary in 2023, staff could raise a toast to the future. Surry was one of the first plants to file a subsequent license renewal (SLR) application, and in May 2021, it became official: the plant was licensed to operate for a full 80 years, extending its reactors’ lifespans into 2052 and 2053.

Unirradiated Vanstar-7 alloy was tested in fatigue at room temperature, 550°, and 650°C, respectively, in high vacuum below 10−5 Pa. The test data were analyzed and compared with those of V-15Cr-5Ti and 20% cold-worked type 316 stainless steel tested under the same condition. Results show that the fatigue resistance of Vanstar-7 is in general somewhat lower than that of V-15Cr-5Ti. The low fatigue performance for Vanstar-7 at the elevated temperatures in the high cycle range may be attributable to thermal creep damages because Vanstar-7 is less creep resistant than V-15Cr-5Ti. However, Vanstar-7 exhibits superior fatigue resistance compared with the stainless steel in the low strain range below 0.5% strain.
