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 radon adsorption ability of four samples of coconut shell-based activated carbons has been investigated by measuring the dynamic adsorption coefficient (DAC) of each activated carbon in a radon room. The findings obtained have shown that DACs are dramatically different even when the surface areas are near. Nitrogen adsorption and X-ray photoelectron spectroscopy analysis are used to study the microstructure of the four samples. The results have shown that micropores with diameters between 0.5 and 0.8 nm play the most important role in radon adsorption on activated carbons. Oxygen on the pore surface influences radon adsorption because of the polarity molecular adsorption on oxygen groups.
