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 neutron reaction data of 181Ta for the incident energy up to 200 MeV are urgently required for the study of nuclear reactor systems of fission or fusion. To meet this requirement, all cross sections, angular distributions, energy spectra, and double-differential cross sections for n + 180m,181Ta reactions are consistently calculated and analyzed at incident neutron energies up to 200 MeV. The theoretical results are compared with the experimental data and the evaluated results in ENDF/B-VIII, JENDL-4, and JEFF-3.
