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.

A new hard X-ray (HXR) camera system has been planned to be developed for HL-2A tokamak (R0 = 1.65 m, a = 0.4 m, Bt = 2.8 T, and Ip = 0.5 MA), which is dedicated to the tomography of fast electron bremsstrahlung emission in the energy range 10 to 200 keV. The camera system includes two independent HXR cameras, which are both located in the same poloidal plane. Each camera is made up of 30 detection chords and views the whole poloidal cross section of the plasma. The spatial and temporal resolutions of the camera are 2 to 3 cm and 1 to 2 ms, respectively. HXR detection is performed using cadmium telluride (CdTe) semiconductors. Both simulation and experimental results suggest that an Al foil with a 0.3-mm thickness is the best candidate for filtering the low-energy X-ray photons. Powerful inversion techniques are employed to obtain the local HXR profiles as functions of time and photon energy. The HXR camera system planned for HL-2A tokamak is presented in detail.
