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 paper presents research results of permeability of hydrogen isotopes through CrNi35WTiAl alloy containing radiogenic helium, and results of hydrogen and radiogenic helium impact on mechanical properties of this alloy. The impact of hydrogen and radiogenic helium on mechanical properties of CrNi35WTiAl alloy was determined by tensile tests of cylindrical samples in inert and hydrogen atmospheres. For this research samples with various concentrations of 3He (90, 230 and 560 appm) were prepared. The buildup of 3He has been fulfilled using the “tritium trick” technique. Maximal influencing of hydrogen and radiogenic helium on mechanical properties of CrNi35WTiAl was observed at 873 K on samples with 560 appm of 3He. Testing of permeability of hydrogen isotopes was made in temperature range from 723 to 973 K.
