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.

The Helium blanketing effect on LaNi5-xAlx and ZrCo alloy is researched. Hydrogen absorption and desorption change due to gaseous helium has been investigated by the serial experiments under different conditions. Helium reduces hydrogen absorption and desorption rate, but it would not change the ultimate quantities of hydrogen absorption and desorption. The surface electron spectrum of LaNi5-xAlx was examined by a multi-functional spectrometer. The examination shows that inert gas would not affect the electron state of the alloy surface and also the decomposition and absorption course of hydrogen molecule on the alloy surface. The research shows that Helium blanketing course is divided into two stages of "bulk flow" and "diffusion flow". After reaching the blanketing pressure the microcosmic course is molecule migration controlled by diffusion.
