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.

This paper presents a W mockup with an interlayer of diamond/Cu (DC) composite material. As a joining interlayer, DC composite material has high thermal conductivity and accommodative coefficient of thermal expansion. By adjusting the thickness of the DC layer and comparing different forms of armor, the optimal design is the brush armor mockup with a 1-mm-thickness DC layer. The thermal-structural behavior of this mockup was analyzed under the steady-state and transient heat flux by using ANSYS Workbench. The calculated temperature and stress indicate that the mockup can tolerate 10 MW/m2 steady-state heat flux at most. Then a transient heat flux (300 MW/m2 for 5 ms) is loaded on the top surface upon steady-state heat flux of 8 MW/m2. The surface temperature instantly rises to 2300°C, but a cracking trend is not shown at the loaded surface.
