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.

All cross sections of neutron-induced reactions, angular distributions, energy spectra, and double-differential cross sections are consistently calculated and analyzed for n + 27Al reactions at incident neutron energies below 200 MeV based on the nuclear theoretical models. The optical model; the unified Hauser-Feshbach theory and exciton model, which includes the improved Iwamoto-Harada model; and the distorted wave Born approximation theory are used. Theoretical calculated results are compared with the experimental data and the evaluated results in ENDF/B-VII and JENDL-3. The optical model potential parameters are obtained according to the experimental data of total and nonelastic scattering cross sections and elastic scattering angular distributions.
