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.

Mass attenuation coefficient, effective atomic number, and electron density of 12 organic acids, acetic acid (C2H4O2), acrylic acid (C3H4O2), benzoic acid (C7H6O2), butyric acid (C4H8O2), citric acid (C6H8O7), formic acid (CH2O2), lactic acid (C3H6O3), malic acid (C4H6O5), oxalic acid (C2H2O4), salicylic acid (C7H6O3), tartaric acid (C4H6O6), and valeric acid (C5H10O2), were computed in the wide energy range of incident photon energies from 1 keV to 100 GeV. The variation of these parameters has been studied as a function of incident photon energy. Further, a comparative study of two different methods used to compute effective atomic number is completed.
