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.

Estimated cross sections for neutron production from triton bombardment of gold are deduced from measurements of triton interactions with gas targets that used gold as a triton beam stop material. Differential cross sections for production of neutrons from 5.97-, 7.47-, 10.45-, 16.41- and 19.14-MeV tritons on 197Au were evaluated. Corrections for the neutron interaction in gold, in the target structure, and in the air of the flight path were obtained by means of a Monte Carlo technique. Uncorrelated scale uncertainties range from 24% to 41% whereas those of double-differential cross sections range from 0.2% to 5%. Based on these cross-section data, calculation of neutron yield at 0 deg from fully stopped tritons at 20.22 MeV agrees with an independent measurement. Least-squares fits with a gamma distribution model indicate an anisotropy in the high-energy portion of the neutron spectra. Legendre polynomial fits of differential cross sections are reported. All neutron cross-section data are made available through the Experimental Nuclear Reaction Data (EXFOR) library at international data centers.
