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.

Time-of-flight ultrasonic measurements were conducted on a thick hexagonal block of 304 stainless steel irradiated to ∼33 dpa in EBR-II, and the results of ultrasonic-implied void swelling and carbide-induced densification were compared with those obtained by immersion density measurements and TEM observation. The three types of measurement were found to agree rather well with each other. This study confirmed that ultrasonic velocity measurement is a powerful non-destructive technique to measure the through-thickness-average volumetric changes induced by neutrons in thick structural materials.
