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 high-energy 14.7 MeV protons generated from the D-3He fusion reaction can be used to produce medical radioisotopes. Steady-state D-3He operation is possible using Inertial Electrostatic Confinement (IEC); however, the location of the reactions must be known to use them effectively for isotope production. In the University of Wisconsin IEC Device, it has been found that as much as 2/3 of the total D-3He reaction rate can be due to embedded fusion reactions, reactions occurring within the cathode due to ion implantation. Therefore, the cathode surface sees a large, high-energy proton flux. Using a solid molybdenum cathode, and taking advantage of the embedded reactions, about 1 nCi of the medical isotope 94mTc was created via 94Mo(p,n)94mTc in a proof of principle experiment. This represents the first time the IEC concept has been used to produce a radioisotope using D-3He fusion.
